Abstract:
The hybrid yellow catfish exhibits advantages over pure yellow catfish in terms of fast growth, fast development, a high feeding rate, and strong immunity; additionally, it is almost sterile, thus ensuring the conservation of the genetic stock of fish populations. To investigate the sterility mechanism in hybrid yellow catfish (P. fulvidraco (♀) × P. vachelli (♂)), the mRNA and miRNA of the gonads of P. fulvidraco, P. vachelli, and a hybrid yellow catfish were analyzed to characterize the differentially expressed genes; this was carried out to help establish gene expression datasets to assist in the further determination of the mechanisms of genetic sterility in hybrid yellow catfish. In total, 1709 DEGs were identified between the hybrid and two pure yellow catfishes. A KEGG pathway analysis indicated that several genes related to reproductive functions were upregulated, including those involved in the cell cycle, progesterone-mediated oocyte maturation, and oocyte meiosis, and genes associated with ECM–receptor interaction were downregulated. The spermatogenesis-related GO genes CFAP70, RSPH6A, and TSGA10 were identified as being downregulated DEGs in the hybrid yellow catfish. Sixty-three DEmiRNAs were identified between the hybrid and the two pure yellow catfish species. The upregulated DEmiRNAs ipu-miR-194a and ipu-miR-499 were found to target the spermatogenesis-related genes CFAP70 and RSPH6A, respectively, playing a negative regulatory role, which may underscore the miRNA–mRNA regulatory mechanism of sterility in hybrid yellow catfish. The differential expression of ipu-miR-196d, ipu-miR-125b, and ipu-miR-150 and their target genes spidr, cep85, and kcnn4, implicated in reproductive processes, was verified via qRT-PCR, consistent with the transcriptome sequencing expression trends. This study provides deep insights into the mechanism of hybrid sterility in vertebrate groups, thereby contributing to achieving a better understanding and management of fish conservation related to hybrid sterility.

Abstract:
The swimbladder is an internal gas-filled organ in teleosts. Its major function is to regulate buoyancy. The swimbladder exhibits great variation in size, shape, and number of compartments or chambers among teleosts. However, genomic control of swimbladder variation is unknown. Channel catfish ( Ictalurus punctatus), blue catfish ( Ictalurus furcatus), and their F1 hybrids of female channel catfish × male blue catfish (C × B hybrid catfish) provide a good model in which to investigate the swimbladder morphology, because channel catfish possess a single-chambered swimbladder, whereas blue catfish possess a bichambered swimbladder; C × B hybrid catfish possess a bichambered swimbladder but with a significantly reduced posterior chamber. Here we determined the transcriptional profiles of swimbladder from channel catfish, blue catfish, and C × B hybrid catfish. We examined their transcriptomes at both the fingerling and adult stages. Through comparative transcriptome analysis, ~4,000 differentially expressed genes (DEGs) were identified. Among these DEGs, members of the Wnt signaling pathway ( wnt1, wnt2, nfatc1, rac2), Hedgehog signaling pathway ( shh), and growth factors ( fgf10, igf-1) were identified. As these genes were known to be important for branching morphogenesis of mammalian lung and of mammary glands, their association with budding of the posterior chamber primordium and progressive development of bichambered swimbladder in fish suggest that these branching morphogenesis-related genes and their functions in branching are evolutionarily conserved across a broad spectrum of species.

Abstract:
The hybrid between female channel catfish (Ictalurus punctatus) and male blue catfish (Ictalurus furcatus) is superior in feed conversion, disease resistance, carcass yield, and harvestability compared to both parental species. However, heterosis and heterobeltiosis only occur in pond culture, and channel catfish grow much faster than the other genetic types in small culture units. This environment-dependent heterosis is intriguing, but the underlying genetic mechanisms are not well understood. In this study, phenotypic characterization and transcriptomic analyses were performed in the channel catfish, blue catfish, and their reciprocal F1s reared in tanks. The results showed that the channel catfish is superior in growth-related morphometrics, presumably due to significantly lower innate immune function, as investigated by reduced lysozyme activity and alternative complement activity. RNA-seq analysis revealed that genes involved in fatty acid metabolism/transport are significantly upregulated in channel catfish compared to blue catfish and hybrids, which also contributes to the growth phenotype. Interestingly, hybrids have a 40–80% elevation in blood glucose than the parental species, which can be explained by a phenomenon called transgressive expression (overexpression/underexpression in F1s than the parental species). A total of 1140 transgressive genes were identified in F1 hybrids, indicating that 8.5% of the transcriptome displayed transgressive expression. Transgressive genes upregulated in F1s are enriched for glycan degradation function, directly related to the increase in blood glucose level. This study is the first to explore molecular mechanisms of environment-dependent heterosis/heterobeltiosis in a vertebrate species and sheds light on the regulation and evolution of heterosis vs. hybrid incompatibility.

Abstract:
The hybrid between the female channel catfish (Ictalurus punctatus) and the male blue catfish (I. furcatus) is the best genetic type currently available for commercial catfish farming due to their superior traits. However, further genetic improvements can be achieved by selecting parents with increased combining abilities. Twenty female channel catfish and twelve male blue catfish were crossed in a partial factorial mating design, resulting in forty hybrid families. These families were evaluated for early growth in three different rearing systems, including ponds and aquaria. The early growth performance of hybrid catfish was significantly (p < 0.05) affected by the additive gene action of the female parent and the male parent. There were genotype–environment or genotype–age interactions affecting the combining abilities, both the amount and the type of genetic variation. Dam GCA was significant in all environments/ages; however, sire GCA was variable, and SCA was not significant. These findings suggest that reciprocal recurrent selection for growth could potentially improve the performance of F1 hybrid catfish.

Abstract:
Crossbreeding is a traditional breeding technique and has been performed successfully in many fish species. However, distant hybridization between different genera is hard to be successful because of reproductive isolation. In this study, diploid hybrids (PL) were successfully derived from the hybridization of Ussuri catfish (Pseudobagrus ussuriensis, PU, ♀, 2n = 52) and longsnout catfish (Leiocassis longirostris, LL, ♂, 2n = 52). And the morphological data, external frame parameters, chromosomal karyotypes, DNA content measurement, mitochondrial DNA control region, and species-specific marker identification were applied to investigate the traits and genetic characterization of the PL hybrid offspring and their parents. Both quantifiable traits and shape frame parameters of the PL hybrid offspring were revealed to be intermediate between those of their parents; however, cluster analysis showed that their external morphology was more in favor of the maternal PU. The growth comparisons showed that the hybrids had significant growth advantages over maternal PU. Based on karyotype patterns, DNA contents and mitochondrial DNA, the hybrid origin and maternal inheritance of hybrid offspring were further confirmed. According to the sequence variations identified from the genome sequences of the two catfish species, one species-specific marker was developed to distinguish the PL hybrid offspring and their parents. Therefore, this study provides a successful case for intergeneric hybridization and hybrid superiority, and the PL hybrid shows promise for commercial application, pending further studies into its husbandry, health, and welfare with larger populations of fish.

Abstract:
To improve technologies in the field of commercial cultivation of aquaculture objects and further development of the warm-water aquaculture sector in Russia, we previously undertook breeding methods and approaches to obtain high-quality planting material for a promising commercial object — the African catfish Clarias gariepinus. This article presents, in a comparative aspect, the experience of growing hybrid offspring of African catfish, obtained from crossing two breeds — Mikhailovskaya and Tamanskaya, in a closed water supply system and in a pond farm in the Astrakhan region in the summer. It was shown that hybrid individuals of clariid catfish bred in a pond farm during the feeding period under consideration (from July to September) were characterized by a high specific growth rate and low feed ratio compared to hybrids grown in a recirculation system, respectively, 11.4% versus 9.87% and 0.96 versus 1. Also, based on the results of fishing, over two months of cultivation in a pond farm, hybrids of clariid catfish increased the total biomass by 13 times, while in a recirculating system it increased by 15 times, but the final biomass of fish turned out to be greater when reared in open reservoir (46.875 versus 10.87 kg). It was shown that the final individual mass of hybrid fish cultured in pond conditions was 11.0% higher than the final mass of individuals in the recirculation system. The conducted studies showed that in the climatic conditions of the Astrakhan region (VI fish-breeding zone), a promising direction for aquaculture of African catfish is the feeding cultivation of hybrid juveniles in pond farms. It should be taken into account that in order to obtain marketable fish products (i.e. individuals weighing over 1000 g), it is necessary to use fish seeding material with an average weight of at least 100 g.

Abstract:
Nuclear DNA content (NDC) of species or population is believed to have been formed naturally by many mechanisms such chromosomal mutation, insertion and deletion, transposable element, and duplication. Additionally, hybridizations and species’ phylogenetic relationship may also contribute to the NDC diversity. This study was aimed to investigate the profile of NDC in four species Asian catfishes of the genera Pangasius including Pangasionodon hypophthalmus, Pangasius djambal, Pangasius nasusutus, Pangasius nieuwenhuisii, interspecific hybrid of female P. hypophthalmus and male P. djambal (Hybrid HD), and female P. hypophthalmus and male P. nasutus (Hybrid HN). Red blood cells (RBC) were taken from the respective species/groups and NDC measurement was performed in an Attune acoustic flowcytometer (ABI) using DAPI staining and chicken, Gallus domesticus, RBC was used as size reference. The results showed that the mean NDC of P. hypophthalmus, P. djambal. P. nasusutus, P. nieuwenhuisii, were 0.960±0.0254 pg, 1.017±0.0510 pg, 1.000±0.0410 pg, 1.074±0.0231 pg, which are within the range of NDC in the other catfish families The NDC values of Hybrid HD and Hybrid HN were1.005±0.0358 and 0.956± 0.0089, respectively. Among the pure line species, the NDC of P. hypophthalmus was the lowest and was different (P<0.05) from those of P. djambal and P. nieuwenhuisii but was not different (P>0.05) from that of the P. nasutus. The NDC of both Hybrid HD and Hybrid HN were not different form their respective parental lines. However, the NDC profiles of both hybrids were different in that the NDC of the former was in between while the latter was below their respective parental lines. Phylogenetically, the NDC diversity within Pangasiid catfish in this study was independent of their phylogenetic relationship based on cytoplasmic and nuclear markers.

Abstract:
Catfish is a commonly-cultivated freshwater fish in Thailand and many Southeast Asian countries. The molecular data obtained for the IgM heavy chain (IgMH) of catfish have been useful for distinguishing monoclonal antibodies (mAbs). A mAb specific to Cμ1 of the IgMH of catfish (IgMHCμ1 mAb) was developed in a rabbit model using sequence information from bighead catfish (Clarias macrocephalus). The IgMHCμ1 mAb strongly recognized the IgM heavy chain of the tested catfish, namely, bighead catfish, African catfish (Clarias gariepinus) and their hybrid (C. macrocephalus × C. gariepinus), in immunological Western blot analysis and competitive ELISAs. Additionally, the IgMHCμ1 mAb successfully recognized IgM+ cells by detecting IgM molecules in both secreted and membrane-bound forms in peripheral blood leukocytes (PBLs). The IgMHCμ1 mAb was further used to quantify the percentage of IgM+ cells among PBLs through flow cytophotometry. The IgM+ cell percentages of healthy bighead catfish, African catfish and their hybrid were 38.0–39.9%, 45.6–53.2%, and 58.7–60.0%, respectively. Furthermore, the IgMHCμ1 mAb showed no cross-reactivity with the IgM of zebrafish. These findings suggest that this mAb can be used as an immunological tool for monitoring the health, immune status, and immune development of cultivated Clarias catfish.

Abstract:
The aim of this study was to evaluate the aquaculture potential of a hybrid between the two largest African silurid catfish, Heterobranchus longifilis (HL) and Clarias gariepinus (CG) . A morphometric, meristic and karyological study showed that the hybrid shared some of the physical characteristics of both C. gariepinus and H. longifilis, while its chromosome complement and fundamental number (2N = 54, FN = 95), was intermediate between that of H. longifilis (2N = 52, FN = 92) and C. gariepinus (2N = 56, FN = 97). The HLxCG cross could therefore be regarded as a true hybrid. For the characters tested, no morphological or karyological differences were apparent between the HLxCG hybrids produced in West Africa and those produced in southern Africa. In southern Africa, the HL♂xCG♀ cross had higher fertilization and hatching rates than pure strain H. longifilis, C. gariepinus or the reverse cross. There was no difference in the survival of the HL♂xCG♀ hybrid larvae and C. gariepinus larvae up to the onset of exogenous feeding. Pure strain H. longifilis juveniles had a faster growth rate than the H. longifilis ♂ x C. gariepinus ♀ juveniles, but the hybrid always grew at a faster rate than C. gariepinus or the reverse cross. The HL♂xCG♀ cross was consequently chosen as the hybrid with the greatest potential for siluroid aquaculture in southern Africa. The HL♂xCG♀ hybrid showed evidence of partial gonadic, gametic and post-zygotic sterility in both sexes. The hybrid was not completely sterile, as it was artificially induced to spawn, and a small number of viable F₂ hybrid and F₁ hybrid x C. gariepinus larvae were produced. However, in the light of its probable reproductive strategy, it is highly unlikely that the hybrid would pose an ecological risk to the southern African region. The H. longifilis ♂ x C. gariepinus ♀ hybrid was compared to C. gariepinus for selected water quality preferences and tolerances. The hybrid had a wider temperature preference (28 °C to 34 °C) than C. gariepinus (28 °C to 30 °C), but appeared to be more dependent on aerial respiration than C. gariepinus. The air-breathing frequency of hybrid fish began to increase at dissolved oxygen concentrations below 3 .8 mg.ℓ⁻¹, while C. gariepinus only showed an increase in air-breathing frequency at concentrations below 3.0 mg.ℓ¹. The hybrid was more tolerant of un-ionised ammonia (96-hour LC₅₀ = 9.1 mg.ℓ⁻¹) than C. gariepinus (96-hour LC₅₀ = 6.5 mg.ℓ⁻¹), but their 96-hour LC₅₀ salinity tolerances were similar (10.8-11.0 g.ℓ⁻¹). The H. longifilis ♂ x C. gariepinus ♀ hybrid had a higher fillet yield (43.9 %) than C. gariepinus (38.9 %), but the crude protein content and amino acid profile of the two groups were similar. Catfish are traditionally grown in earthen ponds under semi-intensive conditions in southern Africa, at around 4 kg of fish per cubic meter of water (kg.m⁻³). However, the hybrid could tolerate densities of up to 415 kg of fish per cubic metre of water, if the water was exchanged hourly (kg.m⁻³.hr⁻¹), and the density at which yield was optimised was rounded off to 400 kg.m³.hr⁻¹. The high threshold density and water quality tolerances of the H. longifilis ♂ x C. gariepinus ♀ hybrid indicates that it is ideally suited for highly intensive aquaculture. It was concluded that it would be more productive to farm the HL♂xCG♀ hybrid on an intensive basis in southern Africa, than it would be to farm C. gariepinus in the traditional manner.

Abstract:
Hatchery techniques and technologies have evolved to make the large-scale production of channel catfish (Ictalurus punctatus) × blue catfish (I. furcatus) hybrids viable and profitable, but there are still reproductive roadblocks between the two species, leading to inconsistent fry production. Therefore, it is imperative to assess how gamete interactions, and maternal/paternal effects impact fertilization outcomes and offspring performance traits during the “critical” early life history stages. In this thesis, it was demonstrated that manual spawning practices can be improved and that gamete interactions can cause alterations in sperm performance for hybrid catfish and other cultured fish species. Environmental effects, parental effects, and interactions between them also control many traits early in life, which if linked to specific mRNA transcripts, may be a powerful mechanism to improve gamete and larval quality. Overall, this work has identified the importance of spawning strategies, females, males, and their mating compatibilities for proper broodstock selection.

Abstract:
碩士<br>國立臺灣海洋大學<br>水產養殖學系<br>93<br>The catfish, Clarias fuscus, is an economical species that spreads in most freshwater ponds in Taiwan. Aquacultural merchants have imported two fast-growing and easy-breeding species, Carias batrachus from Thailand and C.mossambicus from the Republic of Central Africa, to hybridize (interbreed) with C. fuscus for reproducing a new fast-growing and quality species. However the market of catfish has declined nowadays. The surviving space of the Catfish in Taiwan has been dwindled as a result of various factors. In addition to water pollutions and degradation of their natural inhibitance, the messed-up species caused by abandonment from farming industry, exposure to natural environment due to deluge, and release by Buddhist has also contribute the problem. Protecting local breeds of Catfishes has been specified as one of the major area of national aquarial resources safeguard. To this date, RAPD has been proved to be one of the most feasible approach to quickly identify the existence of hybrid Catfishes among national open water and aquacultures. This study will move a step further to distinguish between the original and hybrid breeds by taking advantage of the genetic transformation technology to develop distinctive probes that can be used to directly identify the breeds of the Catfishes captured. The molecular genetic technique, RAPD (Random Amplified Polymorphic DNA), was declared by Welsh and Williams’ research groups in 1990. This technique used biological DNA as template and 10 random oligonucleotide bases as primers to proceed PCR amplification. Base on polymorphism of PCR products then progressed genetic analysis. This test followed Huang (2001) and Lin (2003) two previous studies that selected ＃211, ＃245, ＃287 three RAPD primers from John B. H.’s RAPD primer oligonucletide set ＃101-300 to be the identified primer between C. fuscus and C. mossambicus, and proceeded PCR reaction with both fishes’ genomic DNA. Using the specific band of PCR results of C. mossambicus and the general band of C. fuscus and C. mossambicus to transform upon plasmid yT&A and finally, the probe was formed. Genomic DNA of C. mossambicus hybridized with the specific probe successfully. On the contrary, that of C. fuscus failed to hybridize with the probe. Therefore we found out that the probe made by ＃211 and ＃287 were able to distinguish different breeds. In addition to hybridizing the catfish from other regions of Taiwan and aquaculture with the specific probe, the results showed that two sample catfish from Miaoli county and partial catfish of Yuanlin township,Yuanshan township and Hualien county all hybridized with the specific probe. Catfish gathered from other natural waters were not yet hybridized with C. mossambicus.

Abstract:
&lt;em&gt;Abstract.-&lt;/em&gt;The Arkansas Game and Fish Commission’s Family and Community Fishing Program was developed in 2002 after a 3-year pilot study. The program’s goal is to enhance or create destinations in highly populated areas so that excellent fishing is available to all Arkansans. The program has grown from stocking catchable fishes in 10 locations in 2002 to 36 locations in 2007. In 2007, approximately 68,000 channel catfish &lt;em&gt;Ictalurus punctatus &lt;/em&gt;and 65,000 rainbow trout &lt;em&gt;Oncorhynchus mykiss &lt;/em&gt;were stocked in spring/summer and winter, respectively, in 22 cities. Channel catfish and rainbow trout were both stocked at approximately 200 fish per acre per month. Hybrid striped bass &lt;em&gt;Morone saxatilis &lt;/em&gt;x &lt;em&gt;M. chrysops &lt;/em&gt;were stocked at 50-100 fish per acre when fish became available. Trophy blue catfish &lt;em&gt;Ictalurus furcatus &lt;/em&gt;from 15 to 60 lb were stocked on occasion to increase media attention and generate angler excitement at Program locations. Anglers were permitted to harvest three channel catfish, three hybrid striped bass, and five rainbow trout per day with no length restrictions. Largemouth bass &lt;em&gt;Micropterus salmoides &lt;/em&gt;were catch and release only and the sunfish &lt;em&gt;Lepomis &lt;/em&gt;spp. daily limit was 25. Ten fishing derbies and 14 fishing clinics were provided free to the public in 2007 to facilitate angler education and family participation. The Program has provided an opportunity for thousands of Arkansans to fish with friends and family in convenient locations.

Abstract:
&lt;em&gt;Abstract.-&lt;/em&gt;Demographic studies have indicated that, since 1990, Kentucky’s urban population has experienced an 18% increase while its rural population has expanded by less than 1%. These demographic changes, coupled with a decline in fishing license sales, focused the need to develop and increase fishing opportunities in and around urban areas. In 2005, the Kentucky Department of Fish and Wildlife Resources initiated a pilot urban fishing program aimed at providing urban residents with high quality fishing opportunities close to home. Five pilot lakes, located within four of Kentucky’s most populated counties, were selected to receive regular stockings of rainbow trout &lt;em&gt;Oncorhynchus mykiss&lt;/em&gt;, channel catfish &lt;em&gt;Ictalurus punctatus&lt;/em&gt;, largemouth bass &lt;em&gt;Micropterus salmoides&lt;/em&gt;, and hybrid bluegill &lt;em&gt;Lepomis macrochirus &lt;/em&gt;x &lt;em&gt;L. cyanellus&lt;/em&gt;. Rainbow trout were stocked at each lake in April and October. Channel catfish, largemouth bass, and hybrid bluegill were stocked in May and June. Monthly stocking rates were 202 trout/ha, 34 channel catfish/ha, 12 largemouth bass/ha, and 81 hybrid bluegill/ha. Creel and angler attitude surveys were conducted at two of the pilot lakes from April through August 2006 to determine angler catch and satisfaction. Although fishing pressure at these two lakes was high, most anglers practiced catch and release. Catch rates were 1.03 fish/h at Stein Lake and 0.79 fish/h at Upper Sportsman’s Lake. Angler attitude survey results indicated that the majority of anglers interviewed were not aware of the program and did not know that regular fish stockings were occurring at the lakes. The typical angler fishing these lakes was a white male between the ages of 30 and 49, who was satisfied with his fishing experience regardless of the number or size of fish caught. Further studies need to be completed to compare results from this study, and to refine stocking and marketing techniques used in the program.

Abstract:
&lt;em&gt;Abstract.-&lt;/em&gt;The Arkansas Game and Fish Commission’s Family and Community Fishing Program was developed in 2002, and catchable channel catfish &lt;em&gt;Ictalurus punctatus&lt;/em&gt;, hybrid striped bass &lt;em&gt;Morone saxatilis &lt;/em&gt;x &lt;em&gt;M. chrysops&lt;/em&gt;, and rainbow trout &lt;em&gt;Oncorhynchus mykiss &lt;/em&gt;have been stocked into ponds and streams seasonally each subsequent year. One of the goals of the program has been to provide families and children with a convenient and excellent chance to catch fish. A toll-free stocking hotline (1-866-540-FISH) was initiated in January 2006 to inform anglers when and where fish had been stocked, so they could plan their fishing trips to program destinations accordingly. Hotline information was provided for 22 ponds during catfish season (April through November) and 17 ponds plus one stream during trout season (December through March). The hotline was generally updated within two hours after stocking, and consisted of information regarding immediate past stocking events as well as general fishing tips. Anglers placed 11,822 calls and spent 15,394 min of call-time on the hotline between January 2006 and May 2007. The number of calls peaked during catfish stocking season in June and was lowest during the September stocking off-season. On average, the hotline cost approximately $40 per month to operate and was four to six times less expensive than paying Commission personnel to answer stocking questions on the telephone. More than 36% of the hotline calls were placed outside of Commission business hours (0800-1630 hours), indicating that anglers were taking advantage of the 24-h information line. A toll-free hotline is a popular, inexpensive, and cost-effective means of supplying stocking information, allowing anglers to make informed decisions when choosing a day and location to fish at program locations.

Abstract:
&lt;em&gt;Abstract.-&lt;/em&gt;The St. Louis Urban Fishing Program (UFP) was established in 1969 to provide close-to-home fishing opportunities for urban anglers in St. Louis, Missouri through regular fish stockings at five lakes, totaling 8.4 hectares. Urban Fishing Clinics (UFC) were added for children and therapeutic patients in 1971 and 1979, respectively. Since 1973, UFP has been funded and administered by the Missouri Department of Conservation (MDC) with cooperation from municipal partners. Stocking rate, stocking schedule, and fishing regulation changes were made in the early 1990s. Since 1993, Community Assistance Program agreements have enabled MDC to improve UFP lake habitats and amenities. Subsequently, similar urban fishing programs have developed in Kansas City, St. Joseph, Sedalia, and Springfield, Missouri. Sportfish lakes are stocked with common carp &lt;em&gt;Cyprinus carpio&lt;/em&gt;, channel catfish &lt;em&gt;Ictalurus punctatus&lt;/em&gt;, hybrid sunfish &lt;em&gt;Lepomis macrochirus &lt;/em&gt;x &lt;em&gt;L. cyanellus&lt;/em&gt;, brown trout &lt;em&gt;Salmo trutta&lt;/em&gt;, and rainbow trout &lt;em&gt;Oncorhynchus mykiss &lt;/em&gt;from MDC hatcheries and commercial sources to create year-round angling opportunities. Annual fish stockings average up to 263 kg/ha, with a total of 1,119,105 kg since 1969. Completion of habitat improvement projects and subsequent successful natural reproduction of sportfish have allowed nine UFP lakes to provide additional opportunities for bluegill &lt;em&gt;Lepomis macrochirus&lt;/em&gt;, largemouth bass &lt;em&gt;Micropterus salmoides&lt;/em&gt;, redear sunfish &lt;em&gt;Lepomis microlophus&lt;/em&gt;, and white crappie &lt;em&gt;Pomoxis annularis&lt;/em&gt;. The UFC lakes are stocked with hybrid sunfish and channel catfish, averaging 152 kg/ha, with a total of 26,771 kg since 1978, and offer fishing program opportunities from April through October. In 2007, UFP lakes consist of 20 sportfish and six UFC lakes, totaling 30.1 hectares. All sportfish and most UFC lakes are partner-owned and located in municipal parks. Annual fishing pressure ranges from 439 to 12,019 h/ha and averages 109,470 trips/ year. Over 48,000 children and therapeutic patients have attended UFC since their inception; however, UFC impacts to angler recruitment and knowledge of aquatic conservation are unknown. So, a new program, GO FISH! was launched in 2007.
