Abstract:
In recent decades, Brazilian hydroelectric reservoirs have been stocked with hundreds of millions of juvenile migratory fish, but almost no research on stocking has been conducted. In order to study stocking it is essential to tag the fish to be stocked. In this investigation we determined handling-induced mortality, tag retention rate, and absolute growth rate of hatchery-reared juvenile curimbatá (Prochilodus lineatus) tagged with coded wire tags (CWT), a tag widely used on stocked fish. We injected CWT into the dorsal musculature just below the first dorsal fin ray. Despite the need for frequent tag injector maintenance, this tagging location proved to be suitable for tagging juvenile curimbatá. We found no short-term mortality of juvenile curimbatá handled for CWT tagging, high retention rate for CWT (≥ 98.2%) even after 174 d of tagging, and no influence on absolute growth rate by CWT. We conclude that CWT is effective at tagging juvenile curimbatá, and we expect that it will also be effective for many other Brazilian fish species used for stocking.

Abstract:
The objective of this study was to obtain information about the possible mechanisms related to poor reproductive performance in tropical rheophilic fish. To that effect, cages (Cs) and earthen ponds (EPs) were used as experimental systems to provide unsuitable and suitable conditions, respectively, for curimbatá (Prochilodus lineatus) breeders. Fish were maintained under experimental conditions for 18 months, and during this period females were randomly sampled every two months for biometric analysis (n=30), blood (n=5/sampling) and ovary (n=5/sampling). After this period EPs females (EPFs) and Cs females (CFs) were submitted to the induced breeding experiments. The results showed that rearing curimbatá for such long time in a cage at this stocking density, reduces its growth, plasma E2 levels and vitellogenesis. During vitellogenesis, the mean plasma estradiollevels of CFs were three times lower than those of EPFs (P<0.01). CFs presented poorer results than EPFs for all the examined parameters of reproductive performance. Taken together these data showed that the reduced estradiol levels during vitellogenesis (and the consequently less intense transition from the previtellogenic to vitellogenic phase) and reduced amounts of yolk are mechanisms associated with the formation of low quality oocytes and shortened and delayed breeding season in this species. Moreover, our data showed that the onset of vitellogenesis (six months before the spawning season) must be considered as a key period related to the formation of oocytes of good quality, and adequate management should be provided throughout the year.

Abstract:
Toxicity tests using early life stages of fish are of great importance in assessing risks to growth, reproduction and survival in polluted environments and are important tools for good environmental monitoring. However, a small number of standard bioassays of this type have been developed in Brazil. Curimbatá (Prochilodus lineatus) is an abundant South American characid fish of great commercial interest. It was chosen for testing different concentrations of 40% dimethoate, an organophosphate insecticide and acetylcholinesterase enzyme (AChE) inhibitor used widely in Brazil. The 48-h LC50 for eggs is higher than 16.0 µg.L-1, whereas for recently hatched larvae it was found to be significantly lower (11.81 µg.L-1, ranging between 10.23 µg.L-1 - 13.65 µg.L-1) and also significantl y lower than that for eggs by a Student t-test for independent samples (p = 0.03). The 96-h LC50 for 3-day old larvae was 10.44 µg.L-1 (8.03 µg.L-1 - 13.57 µg.L-1), similar to that of recently-hatched larvae (p = 0.76). Larval mobility was also found to be reduced by this insecticide.

Abstract:
Todos os animais vivem em íntima associação com micro-organismos que desempenham importantes funções em seu desenvolvimento normal. Nos vertebrados, a mais populosa e complexa comunidade de micro-organismos reside no trato intestinal. O intuito do estudo foi quantificar, classificar e verificar morfologicamente a população microbiana intestinal de duas importantes espécies de peixes de água doce, o curimbatá (Prochilodus lineatus) e o cascudo cinza (Pterygoplichthys anisitsi). As amostras foram coletadas por meio de raspagens da mucosa intestinal, diluídas seriadamente até 10-4, semeadas em placas contendo ágar soja tripticaseína (TSA) e ágar chocolate (AC) para contagem de bactérias totais e identificação morfológica por Gram, em aerobiose e em anaerobiose facultativa, respectivamente. As contagens de bactérias totais mostraram resultados que variaram entre 10³ e 10(4)ufc.mL-1. Os tipos morfológicos encontrados foram cocos, leveduras e bastonetes Gram negativos e positivos. Estudos adicionais sobre os padrões de colonização microbiana e a morfologia dos micro-organismos aderidos à mucosa intestinal foram possíveis com o uso da microscopia eletrônica de varredura (MEV), sendo encontradas formas variadas de micro-organismos, tais como leveduras, formas cocoides e bacilares flageladas e não flageladas. A microbiota intestinal do curimbatá e a do cascudo cinza provaram ser bastante diversas e populosas, com o predomínio de micro-organismos Gram negativos.

Eighteen fishes with averages of 46.7 + 1.1 cm length and 1,674.8 + 75.6 g weight were collected with net, bimonthly from December 1995 thru December 1996 in the hydroelectric power station of Volta Grande Reservoir (Cemig), Minas Gerais, Brazil. From analysed fishes, 15 were infected with acanthocephalans in the intestine (prevalence 83.3%). The greatest mean intensity occurred in August 1996 with 66.5 (16 to 208) parasites. Histopathological analysis showed complete desquamation of the intestinal epithelium with severe hyperplasia and hypertrofia of the goblet cells. Severe inflammatory reaction at the submucosa, displacement of their sheaf, associated with oedema and mononuclear and eosinophilic infiltration were observed.

Abstract:
A single farmed fish species assimilates about 20% of the nutrients in the supplied diet. This study evaluated if the culture of complementary ecological-function species can recover nutrients dispersed into water and transform them into high-valued biomass. A completely randomized experiment was designed with three treatments and four replications of each production system: monoculture of lambari (Astyanax lacustris); integrated aquaculture of lambari and Amazon river prawn (Macrobrachium amazonicum); and integrated aquaculture of lambari, Amazon river prawn, and curimbatá (Prochilodus lineatus). Fingerlings of lambari (0.8 ± 0.8 g) were stocked in twelve earthen-ponds (0.015 ha) at the density of 50 fish m−2. Eight ponds were stocked with juveniles of Amazon river prawn (1.1 ± 0.2 g) at the density of 25 prawn m−2. Four of these eight ponds were stocked with curimbatá fingerlings (0.2 ± 0.1 g) at a density of 13 fish m−2. Only lambari was fed twice a day with an extruded commercial diet. The experiment lasted 60 days when lambari attained commercial size. The inclusion of prawn increased the total species yield from 1.8 to 2.4 t ha−1 cycle−1 and reduced the feed conversion ratio (FCR) from 2.5 to 1.8. The inclusion of prawn and curimbatá increased the total yield to 3.2 t ha−1 cycle−1 and reduced the FCR to 1.4. Therefore, the integrated culture of lambari, prawn, and curimbatá improves the use of space, water, feed, and benthic species to recover the large quantity of nutrients accumulated in the bottom of lambari pond production, converting them into high-nutritional and monetary-valued biomass.

Abstract:
Three species of freshwater Brazilian fishes (pacu,Piaractus mesopotamicus; piavussu,Leporinus macrocephalus, and curimbatá,Prochilodus lineatus) were exposed to an acute dose of 5 ppm methyl parathion organophosphate pesticide. Three to five individuals per species were exposed, one at a time, to 40 liters tap water spiked with Folidol 600. Pesticide concentrations and cholinesterase (ChE) activities were evaluated in serum, liver, brain, heart, and muscle. The bioconcentration of methyl parathion was similar for all studied fishes. Brain tissue showed the highest pesticide concentration, reaching 80 ppm after exposure for 30 min to methyl parathion. Three to 5 hours of 5 ppm methyl parathion exposure provoked the death of allP. lineatusat 92% brain AChE inhibition, whereas fish from the other two species survived for up to 78 hours with less than 80% brain AChE inhibition. Our results indicate that acute toxic effects of methyl parathion to fish are correlated with brain AChE sensitivity to methyl paraoxon.

Abstract:
Different pH levels of water in the incubation and larviculture of 'curimbatá' (Prochilodus lineatus) were tested to evaluate the effect of this variable on the survival and development of eggs and larvae. During incubation, pH of 5.0, 6.0, 7.0, 8.0, and 8.5 was tested. To observe the effects of pH on larvae with different hatchery histories, the following experimental design was utilised (pH incubation - pH larviculture): L 6-6; L 6-7; L 7-6; L 7-7; L 7-8; L 8-7; L 8-8; L 8.5-7, and L 8.5-8.5. At pH 5.0 and four hours after incubation, an almost total mortality of incubated eggs was seen. Eggs incubated at pH 6.0 to 8.5 had similar fertilization and survival rates at the end of incubation, although eggs and larvae incubated at pH 6.0 had a smaller diameter and total length than larvae incubated at neutral and alkaline pH. During larviculture, it was observed the highest post-larvae survival rates with incubation at pH values of 7.0 (93 ± 7%) and the largest post-larvae lengths from the L 8.5-7 treatment (9.29 ± 0.8 mm). It can be concluded that hatchery and larviculture pH directly affects the initial developmental stages of P. lineatus.

As rações foram formuladas para serem isoprotéicas (26,00%), isocálcicas (0,90%) e isofosfóricas (0,70%), com níveis crescentes de substituição da proteína do FS pela do FC (0,00; 20,00; 40,00; 60,00; 80,00 e 100,00%), o que correspondeu a 0,00; 8,03; 16,10; 24,10; 32,15 e 43,12% de inclusão do FC nas rações e fornecidas por um período de 30 dias. Os parâmetros físico-químicos da água foram medidos a cada sete dias. Observou-se redução linear do ganho de peso e da taxa de eficiência protéica e aumento linear da taxa de conversão alimentar, com aumento da inclusão do FC nas rações. A taxa de sobrevivência e o custo de ração/kg ganho não foram afetados com o uso do FC nas rações. Os valores da temperatura da água, do pH e da condutividade elétrica permaneceram dentro dos níveis adequados. Concluiu-se que o aumento dos níveis de inclusão da proteína do farelo de canola nas rações para alevinos de curimbatá acarretou redução no desempenho dos mesmos.

Abstract:
AIM: We aimed to evaluate the influence of the correction of the water alkalinity in the fish ponds on the density of zooplankton under a period they were stocked with larvae of Prochilodus lineatus, a neotropical fish called "Curimbatá". METHODS: We used a factorial design completely randomized. In one plot (2 ponds) there was no correction of the alkalinity of the water (20 mg CaCO3.L-1) and in two others, this variable was adjusted weekly to values around 30 and 60 mg CaCO3.L-1 ¹, with two replicates each. Zooplankton was sampled weekly and the experiment lasted 63 days. RESULTS: Significant differences in the density of the zooplankton over time (F = 6.78, p < 0.05) were found and there was a sharp decrease in zooplankton density from first to second week, and successive small increases in density from the fourth week until the end of the experiment. When considering the entire study period, alkalinity correction 60 mg CaCO3.L-1 resulted in higher density of zooplankton. Great changes in zooplankton composition occurred. Rotifera were dominant at the beginning of the experiment and Cladocera and Copepoda in the later weeks possibly due to an interplay of dilution by rain and fish predation in the initial part of the experiment and due to both alkalinity correction and predation by both fish and predatory copepods from the fourth week until the end. CONCLUSION: The experiment corroborated the hypothesis that correction of water alkalinity in ponds does favor zooplankton development but also highlighted biotic and abiotic interaction of factors operating simultaneously.

The kidney tissue collected after 24 hours of exposure showed an enlargement of intercapsular space with glomerular atrophy, hypertrophy of the kidney tube cells, with small granules on its cytoplasm and little nuclear alteration. Blood overflowing from capillaries with pyknotic nuclei and vacuoles in the cytoplasm it was also noticed. After 48 hours, the kidney tissue showed glomerular expansion, impossibility to visualize the intercapsular space as well as cytoplasm limit of many cells. The parietal capsular epithelium and the basal membrane presented loss of cell content, the tubular cells appeared swollen vacuolated and with thin and thick cytoplasmatic granulations. Some of the cell nuclei kept relatively regular form with a condensed chromatin on its central region, while others showed themselves relatively small and pyknotics advancing to a cariolisis and necrosis focus.

The present work described helminth parasites of curimbatá, Prochilodus lineatus Valenciennes, 1836 from Volta Grande Reservoir, MG, Brazil. Eighteen fishes with average 46.7 ± 1.1 cm length and 1,674.8 ± 75.6 g weight were collected. Of the analysed fishes, 15 were parasitized with acanthocephalans in the intestine, showing a prevalence of 83.3%. The helminth was identified as Neoechinorhynchus curemai Noronha, 1973 (Acanthocephala: Neoechinorhynchidae). It differs from other species in dimension of characters and morphology. From the original description of N. curemai, it differs from the biggest dimension of testis, elongated cement gland, nucleated lemnisci, eggs size, larger proboscis hooks length in the middle and in the third circle in males and larger hooks in the anterior circle in females. A smaller percentage occupied by the reproductive system in female trunk was reported. The observation of paratypes of N. curemai of Noronha (1973) showed a great similarity with those of the present work. This fact complements the helminth description from elsewhere.

Abstract:
Este estudo teve como objetivo verificar a ocorrência de diplostomídeos e cimotoídeos em peixes da barragem do rio Serra Branca, do município de Pai Pedro, Norte de Minas Gerais, Brasil. Foram adquiridos de pescadores locais, 15 peixes de quatro gêneros diferentes, sendo eles, Prochilodus, Astyanax, Acestrorhynchus e Leporinus. A musculatura, a região bucal, órgãos, cavidades e globo ocular de cada peixe foram examinados macroscopicamente. Os parasitos encontrados foram coletados e identificados. Foi observado um percentual total de 53,33% (8/15) de positividade, com 46,66% (7/15) do total positivas para metacercárias de diplostomídeos de dois morfotipos: Austrodiplostomum sp. e Sphincterodiplostomum sp., restritas ao globo ocular e 6,66% (1/15) positiva unicamente para espécime da família Cymothoidae, sendo identificado como pertencente ao gênero Braga sp., configurando-se como primeiro registro em Prochilodus lineatus (Curimbatá). A diversidade de metacercárias em peixes da barragem do rio Serra Branca, no Norte de Minas Gerais, mostra, que além da participação dos peixes nativos como hospedeiros intermediários no ciclo biológico destes parasitos, sua participação na rede alimentar local, já que os hospedeiros definitivos dos diplostomídeos são aves piscívoras. Quanto ao isópode, é mais um parasito registrado com capacidade de causar danos físicos a um peixe de importância comercial. Diante disso, serão necessárias pesquisas futuras para determinar as consequências desse parasitismo na ictiofauna dos reservatórios brasileiros. Estes estudos poderão fornecer informações para um melhor aproveitamento dessa atividade zootécnica.

Abstract:
In this paper, we counted the ascending curimbatás at the fish ladder at the Cachoeira de Emas from October, 1992 to September, 1993 in one whole day (24 h period) per month at different observation points in the dam for 5 min every hour. Most of the fish (80%) were counted not in the fish ladder itself, but in two adjacent spillways at its left, perhaps due to the comparatively increased flow as they are narrower than the ladder. The bulk of the migration occurred in September/October. We inspected the degree of injury of the fish in order to examine the hypothesis that larger fish are less injured, however no conclusion was reached. The degree of injury varied between different points and in different months of the year.

Abstract:
This paper presents results of a fishway evaluation performed at the Engenheiro Sérgio Motta Hydroelectric Power Plant (known as Porto Primavera) - CESP, Paraná River, Brazil. The evaluation was designed to quantify entry and passage proportions of 4 long-distance migratory fish species: Brycon orbignyanus (piracanjuba), Piaractus mesopotamicus (pacu), Prochilodus lineatus (curimba), and Rhinelepis aspera (cascudo-preto). Proportions finding and entering the fishway differed between species, ranged from 7.4 % (Prochilodus lineatus) to 55.4% (Piaractus mesopotamicus). Also, proportion passing was different between species, ranged from 31% (R. aspera) to 100% (Prochilodus lineatus). Fish that were marked and released within the fishway had greater failure rates than those that entered volitionally. Total time to pass ranged from 1.48 hours (Prochilodus lineatus) to 178.9 hours (R. aspera). Failure rates were greatest in the lower end of the fishway. Although some individuals of all species passed successfully, significant challenges remain to restoring connectivity of the upper Paraná River.

Abstract:
<p class="Pa7">Cryopreservation of Curimba semen (Prochilodus lineatus) is ecological and commercial importance. The objective of this study was to evaluate the effect of different concentrations (2, 5, 8 and 11%) of dimethyl sulfoxide (DMSO) diluted in Betsville Thawing Solution (BTS) on the quality of post-thaw semen Curimba. We analyzed the rate and period motility, sperm viability, membrane integrity and DNA, mitochondrial functionality, and fertilization and hatching rate. The plasma membrane and DNA integrity of a DMSO concentration of 11% obtained better results than the concentration of 5% (p &lt;0.05). However, treatment of 5% DMSO resulted in a longer latency and a higher fertilization rate and hatching, in other sperm quality equal to that of fresh semen. The results of this study indicate that 5% DMSO is ideal for cryopreservation of semen Curimba.</p>

Abstract:
The present study aimed to investigate the effect of different soluble biodiesel fraction (SBF) concentrations from burnt soy oil on the embryonic development of curimba (Prochilodus lineatus). The embryos were obtained from semi-natural spawning, collected and transferred to an experimental nursery, in duplicate, under constant aeration, containing different SBF concentrations: treatment I (control), treatment II (0.0645 g.L-1), treatment III (0.129 g.L-1), treatment IV (0.645 g.L-1), treatment V (1.29 g.L-1) and treatment VI (6.45 g.L-1). Mean water quality variables were temperature 23.0 &plusmn; 0.1&deg;C, dissolved oxygen 4.58 &plusmn; 0.34 mg/L and pH 7.3 &plusmn; 0.1. Fish fertilization rates ranged from 50.88 to 81.61%, undergoing alterations beginning at treatment IV (p&lt;0.05). From the tenth hour post-fertilization, delays in embryonic development were observed in relation to the control treatment. Hatching rates ranged from 7.56 to 46.26%, with all groups statistically differing from group I (controls). It is concluded that the different soluble biodiesel fractions interfere in curimba (Prochilodus lineatus) embryonic development.

Abstract:
We studied gill parasites of Prochilodus lineatus in the San Javier River, which is connected to the Middle Paraná System (Santa Fe, Argentina). In 25 specimens, the parasite prevalence in branchial organs was 92% and the average intensity was 8.3 parasites/infested fish. The parasite community showed no dominance of any taxon, but the family Dactylogyridae represented 60% of the community. We found a significant association betweenTereancistrum curimba and Dactylogyridae specimens. The prevalence of the parasites T. toksonum and T. curimba was higher than what has been recorded in the floodplain of the Upper Paraná River, Brazil, demonstrating that the geographic distribution of parasites belonging to Tereancistrum genus is thus expandeing.

Abstract:
This study investigated the addition of antioxidants vitamin E and reduced glutathione on curimba (Prochilodus lineatus) semen cryopreservation and compared sodium bicarbonate solution and distilled water as activators. The experiment was conducted at the environmental station of CEMIG, in Itutinga-MG, Brazil, between December/2009 and January/2010. Semen samples (n = 7) with semen motility above 80% were diluted in cryoprotectant solutions composed of 10% methanol, 15% lactose and containing different concentrations of antioxidants: 50 (VE50), 100 (VE100) and 250 (VE250) µM of vitamin E, and 0.5 (RG0.5), 1.0 (RG1.0) and 1.5 (RG1.5) mM of reduced glutathione. A solution without antioxidants was used as a control. The semen was diluted at a ratio of 1:4 (100 ìL semen:400 ∝L cryoprotectant solution). The toxicity of the solutions was evaluated by investigating semen motility after 10 min in the solution. The rest of the diluted semen was placed into 0.5 mL straws maintained in nitrogen vapour for 24 hours and packed into a nitrogen liquid cylinder for four days. The samples were thawed in a water bath at 60°C for 8 s and the rate (%) and duration (s) of semen activation with distilled water or sodium bicarbonate was evaluated. In the toxicity test, we found that vitamin E and reduced glutathione were not toxic to curimba semen at any of the tested concentrations (P>0.05). The duration of motility was longer (P<0.05) in semen activated with sodium bicarbonate 1% (163 ± 11 s), which was considered the best activator for semen under these conditions. No significant differences were found between the cryoprotectant solutions used after freezing (P>0.05). Thus, the antioxidants vitamin E and reduced glutathione did not improve the quality of cryopreserved curimba semen, but they did not cause toxic effects to the semen in natura and they did not decrease its quality during cryopreservation.

Abstract:
Objetivou-se avaliar a influência de ativadores com diferentes osmolaridades e taxa de diluição na ativação de sêmen criopreservado de curimba (Prochilodus lineatus). Foram utilizados quatro reprodutores machos capturados na Estação de Piscicultura da CEMIG, Itutinga, MG. As amostras de sêmen foram diluídas em duas soluções (DMSO + lactose e metanol + lactose) na proporção de 1:4 e congeladas. Foram avaliadas as taxas (%) e duração (s) da motilidade espermática dos tratamentos. Na ativação foram utilizados ativadores contendo as respectivas osmolarida-des: 30, 99, 183 e 293 mOsm nas taxas de diluição de 1:2, 1:4, 1:6, 1:8 sêmen: ativador. A taxa de diluição 1:2 e 1:8 foram estatisticamente significativas para duração da motilidade para o sêmen criopreservado com DMSO. Para a diluição 1:2, o sêmen ativado com o ativador contendo 30 mOsm, apresentou duração de motilidade maior em relação ao sêmen ativado com ativadores com 183 e 293 mOsm. No entanto, para a utilização do ativador com 30 mOsm, se obteve maior duração da motilidade na diluição de 1:2 em relação a diluição de 1:4. Na taxa de diluição 1:6, quando o sêmen foi ativado com o ativador de 30 mOsm, a taxa de motilidade foi superior à apresentada pelo sêmen que foi ativado com 293 mOsm. Na taxa de diluição de 1:8, o uso de ativador contendo 99 mOsm apresentou maior duração de motilidade em relação ao uso do ativador com 293 mOsm. Ativadores contendo altas osmolaridades podem proporcionar menores taxas e duração da motilidade em sêmen de curimba (Prochilodus lineatus) crio-preservado com os crioprotetores metanol ou DMSO.

Abstract:
The genetic variability of the "curimba", Prochilodus lineatus, from three locations in the Paraná river basin, was investigated by starch gel electrophoresis. A total of 160 specimens were analyzed for 19 enzymes, 12 of which permitted successful interpretation of electrophoretic patterns. Eighteen loci were identified and six of them proved to be polymorphic (EST-1*, EST-2*, IDH-1*, PGM-1*, PGM-2*, LDH-2*). Mean heterozygosity was considered high (13%) by comparison with the literature. A low level of differentiation was found among subpopulations, with mean F ST = 0.018. Values of genetic distance and genetic identity suggest that, at least along this stretch of the river, P. lineatus comprises a single breed with high gene flow. This analysis has important implications for fishery management, aquaculture, and conservation of the stocks

O objetivo do presente trabalho foi avaliar a criação da tilápia do Nilo (Oreochromis niloticus), jundiá (Rhamdia quelen) e curimba (Prochilodus lineatus) em sistema de policultivo em tanque de PVC dentro de estufa plástica. Foi realizado no Laboratório de Tecnologia em Aquicultura (LATAq) Universidade Federal do Paraná Campus Avançado de Jandaia do Sul (UFPR), durante um período de 152 dias entre os meses de dezembro e maio. Foram utilizados 182 peixes, sendo 64 tilápias de 50±5g, 116 jundiás de 15±3g e 02 curimbas de 290±20g em um tanque 27m³. Foram utilizadas rações comerciais extrusadas com 28% proteína bruta. Os parâmetros da água: temperatura, oxigênio dissolvido, pH e nitrogênio amoniacal, foram mensurados durante todo período experimental. Ao final do período foi avaliado o desempenho zootécnico: peso final; ganho de peso; ganho de peso diário; conversão alimentar aparente; rendimento de carcaça; rendimento de filé; sobrevivência e morfometria de comprimento total e comprimento padrão. Ao final do período experimental a produção total de peixes foi de 46,14Kg (1,43kg/m3 ou 14.830 kg/ha) com uma conversão alimentar aparente de 1,66, com a água apresentando uma temperatura média de xxoC durante o período. Portanto, conclui-se que a produção e produtividade deste tipo de sistema apresentam valores interessantes do ponto de vista produtivo levando-se em consideração o tempo de criação e a temperatura média da água, visto que, não são distintos do que se atinge em criação comercial, assim, oferecendo um bom potencial para a sua utilização.

Avaliou-se o quanto fêmeas e machos contribuem para a variação total das taxas de fertilização e de eclosão em curimba (Prochilodus lineatus). Utilizou-se sêmen criopreservado proveniente de cinco machos para fertilizar ovócitos de seis fêmeas em um esquema fatorial cruzado 5x6, totalizando 30 famílias. Além das características reprodutivas dos machos e fêmeas, foram avaliadas as taxas de fertilização e eclosão para cômputo dos efeitos materno e paterno. Os componentes da variância foram estimados por meio da máxima verossimilhança restrita, sendo construídos intervalos Highest Posterior Density (HPD) para cada componente. Verificou-se que as fêmeas contribuíram muito mais para a variação total em relação aos machos para as taxas de fertilização e eclosão. Para a taxa de fertilização, as fêmeas contribuíram com 26,3% da variação total e os machos com 8,9%. Em relação à taxa de eclosão, as fêmeas contribuíram com 11,9% e os machos com 1,6%. Concluiu-se que houve efeito materno sobre as taxas de fertilização e eclosão e que o efeito paterno avaliado individualmente foi pouco expressivo ou até mesmo insignificante.

Abstract:
This paper investigated the effect of cryoprotectant substances on Prochilodus lineatus embryos in an experimental incubator. The prospective study applied combinations of polyvinyl alcohol, hydroxyethyl cellulose, gelatin and fetal bovine serum with dimethyl sulfoxide and ethylene glycol in a new experimental incubator. The morphology of embryos, larval viability and the efficiency of experimental incubators in maintaining the quality of embryos were evaluated. This study demonstrates the efficient association between hydroxyethylcellulose and dimethyl sulfoxide as greater viability (p<0.05) was found for embryos (72.9 ± 23.9%). It should also be noted the permeation of cryoprotectants in embryos through the changes found in chorion diameter, embryo diameter and embryo volume comparing the treatments versus control group (water) (p<0.05), this results can help in future cryopreservation protocols. Although the temperature and oxygenation differed between the usual and experimental incubators (p<0.05), the results showed a high fertilization rate (79.6 ± 13.2%) for experimental incubators (p<0.05) which is sufficient for the maintenance of embryos in a cryoprotective environment and effectively allows experimentation for long periods with cryoprotectant substances. Cryopreservation of fish embryos has not been accomplished yet and new approaches are required for understanding the permeability of teleost embryos, especially in Brazilian native species.

Abstract:
One hundred and forty-eight specimens of Prochilodus lineatus (Valenciennes, 1836) were collected on the Upper Paraná River floodplain, Brazil. Kritskyia boegeri presented significant differences in the abundance according to the host stage of gonadal maturity. Ergasilus sp. presented negative correlation between the GSR of the females and parasite abundance. K. boegeri presented negative correlation between the GSR of the males and abundance. Tereancistrum curimba and Saccocoelioides magnorchis occurred in higher abundance in the open lagoons. Rhinonastes pseudocapsaloideum and S. nanii presented higher abundance in the channels and Tylodelphis sp. presented higher abundance in the closed lagoons and in the rivers. K. boegeri and Amplexibranchius sp. presented significant differences in their abundances between the months of the year. Saccocoelioides nanii presented higher abundances in February-March 2000. Only Tylodelphys sp. presented correlation between fluviometric level and abundance and S. nanii presented significant correlation between water temperature and prevalence.

Abstract:
Neste trabalho, estuda-se experimentalmente o crescimento nas primeiras fases de vida do curimba, Prochilodus lineatus (VALENCIENNES, 1836), pela análise das escamas e tamanho dos peixes. Acompanha-se o surgimento das primeiras escamas e a formação dos anéis "diários", relacionando-os com o tamanho e a idade dos indivíduos. Os resultados mostram que as escamas foram observadas a partir do vigésimo dia em indivíduos que apresentaram tamanhos superiores a 11,2 mm. Isto permitiu a elaboração de uma equação, relacionando o número de escleritos das escamas, a idade dos indivíduos criados em condições experimentais e o dia do ano em que o exemplar (selvagem) foi capturado, resultando no seu dia aproximado de nascimento/eclosão. Outro resultado foi a identificação de duas fases de desenvolvimento, com taxas distintas de crescimento, sendo a primeira compreendida entre o 1º até o 18º dia e a segunda do 19º até o 70º dia.

Abstract:
In recent years, anthropogenic factors such as pollution, overfishing, and construction of hydroelectric plants have significantly impacted natural fish populations. Research focusing on genetically evaluation of these impacts is necessary to objectively target conservation programs. The aim of this study was to evaluate the genetic diversity of Curimba (Prochilodus lineatus), Pacu (Piaractus mesopotamicus), and Piracanjuba (Brycon orbignyanus) populations from the Água Vermelha Reservoir, Rio Grande-SP. Microsatellite loci were amplified, producing 56, 24, and 26 alleles for the populations of the three species, respectively. The number of alleles per locus ranged from three to ten for P. lineatus, two to five for P. mesopotamicus, and two to four for B. orbignyanus. The observed heterozygosity (Ho) was higher in the P. lineatus population (0.547), relative to the P. mesopotamicus and B. orbignyanus populations (0.473 and 0.527, respectively). The mean values of Ho were lower than the average expected heterozygosity (He) in the three species, being corroborated by the positive inbreeding coefficient (Fis). Deviations from the Hardy-Weinberg equilibrium (HWE) were found in five, three, and two loci for P. lineatus, P. mesopotamicus, and B. orbignyanus, respectively. Wilcoxon tests revealed recent bottlenecks in the three species, evidenced by a significant excess of heterozygotes (p < 0.05) detected only in the Infinite Allele Model (IAM). In conclusion, adequate genetic variability was observed in the three populations with the presence of heterozygous deficits.

Abstract:
Fishing in the area of Cachoeira de Emas dates from the aboriginal Painguás who inhabited its margins. The socioeconomic conditions of the fishers and fishing are described, derived from personal interviews with 33 fishers. Their mean age is 48.6 years and they have been fishing on average for 24.2 years. The monthly total raw income is US$ 575.52 and the raw income just from fishing is of US$ 239.64 per fisher. Most of them (66.6%) have only incomplete primary and junior education. The main capture species are curimba Prochilodus lineatus, piapara Leporinus obtusidens, dourado Salminus brasiliensis, mandi Pimelodus maculatus, Pimelodus heraldoi and lambari (genus Astyanax and Roeboides). Fishers capture an average of 19.9 kg of fish per day. The total average raw income just calculated from the interviews is very high when compared with other places in Brazil and in the world, and above the poverty line as defined by the Getúlio Vargas Foundation. So we may conclude there these fishers are not the poorest in society.
