Abstract:

Dog snapper (Lutjanus jocu Bloch and Schneider 1801) and mahogany snapper (Lutjanus mahogoni Cuvier 1828) are infrequently caught snappers in the southeastern U.S. primarily occurring off of southern Florida. The species were opportunistically sampled from commercial and recreational fisheries in the southeastern U.S. from 1979 to 2015. Fish were aged (56 dog snapper and 54 mahogany snapper) by counting opaque zones on sectioned sagittal otoliths. Otoliths of both species were easily interpretable and agreement between readers was acceptable. Analysis of otolith edge-type revealed that annuli formed between May and July on both species. Dog snapper ranged from 200–837 mm total length (TL) and ages 2–33, while mahogany snapper ranged from 270–416 mm TL and ages 2–18. The Von Bertalanffy growth equations were Lt = 746(1–e(−0.20(t−0.32))) and Lt = 334(1–e(0.31(t+1.19))) for dog snapper and mahogany snapper, respectively. The weight-length relations were W = 1.31 × 10−5L3.03(n = 78, r2 = 0.99) and W = 5.40 × 10−6L3.15(n = 79, r2 = 0.79) for dog snapper and mahogany snapper, respectively, where W = whole weight in grams.

Abstract:

The investigation of bathymetric distribution of five snappers caught along the Brazilian Northeastern coast by artisanal fleets through the analysis of the catch composition and relative abundance (CPUE) showed that, on the overall, fished mean size increased along depth and that particular species dominated the catch according to the depth strata. Mutton snapper, L. analis, yellowtail snapper, L. chrysurus, and dog snapper, L. jocu were mainly caught at intermediate depth (20-80m) whereas lane snapper, L. synagris, and silk snapper, L. vivanus, inhabit respectively shallow (<20m) and deep (>80 m) waters. Each fleet category exploited preferentially a particular combination of species and their size range. The fleet dynamic of the Northeast Brazil is technologically heterogeneous and determines the catch composition. Geographical distribution of the fishery and technical interaction between fleets and gears should be considered by the management of these species in order to maintain the sustainability of the stock and to guarantee the continuance of the resource.

Abstract:

Red snappers in the Gulf of Mexico once hovered on the brink of extinction, their population having dropped to 2 percent of what had historically swum in the Gulf. But thanks to a recently introduced plan that turns the conventional wisdom of fisheries management on its head, the picture has begun to change. Called Individual Fishing Quotas (IFQs), the new regulations, which give a guaranteed allotment of fish to each participant instead of applying industry-wide quotas, went into effect for Gulf of Mexico Red Snapper (Lutjanus campechanus) in early 2007. The results were immediate and so profound that the Gulf Fishery Management Council voted earlier this year to increase the annual limit on red snapper to nearly 7 million pounds from 5 million.

Abstract:

Reef fishes have been utilized as food fish throughout the U.S. Caribbean and Gulf of Mexico waters for centuries, with increasing fishing effort in recent decades. As a result, many species have experienced declines in landings, including deepwater snappers such as queen snapper Etelis oculatus and blackfin snapper Lutjanus buccanella. However, little to no peer-reviewed published research exists on basic life history parameters for either species. Confirming the accuracy of an age estimation method for a fish species is essential for ensuring sustainable fisheries management. This is because in the assessment of fisheries species population age-based parameters, including longevity, age at sexual maturity, growth rate, mortality, age-specific reproductive output, and lifetime reproductive output, are important in understanding overall life history strategies of managed stocks. The past stock assessment on U.S. Caribbean queen snapper utilized an estimated longevity of 8 y, derived from length frequencies for fish from St. Lucia. Blackfin snapper has an estimated longevity of 27 y based on a relatively small study from offshore waters of the southeastern U.S. The focus of our investigation was to estimate maximum longevity of two data-poor species in the U.S. Caribbean. The accuracy of ageing methods was tested via bomb radiocarbon age estimation validation and effects of depth on Δ14C in otolith cores and eye lens core values were examined. Results from our work indicate a maximum validated age of 45 y for queen snapper, and 43 y for blackfin snapper. Our findings indicate queen snapper and blackfin snapper are long-lived (> 40 y). The resulting Δ14C comparison between eye lens cores and otolith cores has important implications for the study of age validation, specifically when deepwater species are involved.

Abstract:

Lutjanid snappers are ubiquitous at reef sites in the northern Gulf of Mexico (Gulf), but the degree of niche overlap and basal resource utilization is unknown for most species. Muscle tissue for stable isotope analysis was opportunistically sampled from red snapper (Lujanus campechanus), gray snapper (Lutjanus griseus), lane snapper (Lutjanus synagris), and vermilion snapper (Rhomboplites aurorubens) recreational catches across the northern Gulf. A Bayesian mixing model used to compare resource utilization indicated that Lutjanids occupy niches with varying degrees of overlap among regions but maintain a consistent hierarchy in isotopic composition. Scale shifts among regions were likely due to differences in riverine outflow, nitrogen fixation, and anoxic zones that alter prey abundance or isotopic δ15N ratios. All four Lutjanid species had high percent contributions from particulate organic matter and benthic microalgae with little contribution by macroalgae to any species in any region. Ontogenetic shifts in stable isotope values were observed in most species indicating that size plays an important role in avoiding niche overlap due to intense competition for high-value prey items among congeners at isolated reef sites. Diet specialization is modest but likely plays an important role in avoiding complete niche overlap.

Abstract:

Species delimitation is a major quest in biology and is essential for adequate management of the organismal diversity. A challenging example comprises the fish species of red snappers in the Western Atlantic. Red snappers have been traditionally recognized as two separate species based on morphology: Lutjanus campechanus (northern red snapper) and L. purpureus (southern red snapper). Recent genetic studies using mitochondrial markers, however, failed to delineate these nominal species, leading to the current lumping of the northern and southern populations into a single species ( L. campechanus ). This decision carries broad implications for conservation and management as red snappers have been commercially over-exploited across the Western Atlantic and are currently listed as vulnerable. To address this conflict, we examine genome-wide data collected throughout the range of the two species. Population genomics, phylogenetic and coalescent analyses favour the existence of two independent evolutionary lineages, a result that confirms the morphology-based delimitation scenario in agreement with conventional taxonomy. Despite finding evidence of introgression in geographically neighbouring populations in northern South America, our genomic analyses strongly support isolation and differentiation of these species, suggesting that the northern and southern red snappers should be treated as distinct taxonomic entities.

Abstract:

This study offers a comprehensive morpho-histological analysis of the gastrointestinal tract (GIT) of the Malabar red snapper. A comparison of its GIT morphology with that of the Asian seabass reveals similarities and differences between the two species. Additionally, the moisture content, crude protein, and ash in the fillets of Malabar red snapper and Asian seabass were slightly different, with Malabar red snapper exhibiting higher levels of essential fatty acids. Furthermore, higher levels of the polyunsaturated fatty acid (PUFA)/saturated fatty acid (SFA) ratio and docosahexaenoic acid (DHA)/eicosapentaenoic acid (EPA) ratio, and a lower omega-6/omega-3 ratio, were observed in Malabar red snapper compared to Asian seabass. The Malabar red snapper’s esophagus featured protective mechanisms such as simple columnar epithelial cells, mucous-secreting glands, and goblet cells that were predominantly stained for acid and neutral mucosubstances. Furthermore, its stomach, with mucus cells that were weakly stained for acid mucosubstances, exhibited distinct regions with varying glandular densities, with the pyloric region featuring few glands. The pyloric caeca of the fish were composed of five finger-like structures and few goblet cells. Several goblet cells gradually increased from the anterior to the posterior region of the intestine. These findings provide useful insights for the aquaculture sector, focusing on Malabar red snapper.

Abstract:

Abstract The mangrove red Snapper (Lutjanus argentimaculatus) is a high-value marine fish and ideal culture species. The study was conducted to evaluate the growth and survival rate of mangrove red snapper fed with different diet types. The study was laid out in a randomized setup using three (3) treatments: Treatment 1- Trash fish, Treatment 2- Golden apple snail, and Treatment 3- Fiddler Crab using One- way ANOVA as a statistical tool. Based on the result of the study, mangrove red snappers fed with Trash fish gained the highest growth rate in terms of length, width, and weight of 8.89 cm, 2.19 cm, and 63.46 g. However, samples fed with fiddler crab (T3) obtained the lowest growth rate in terms of length, width, and weight of 3.72 cm, 1.06 cm, and 43.86 g. This study demonstrates that the samples got a 100% survival rate regardless of the treatment used. Furthermore, the result showed a significant difference in the growth rate of Mangrove Red Snapper in terms of length F=2100.544, width F=175.280, and weight F=319.770 with P<0.0001. Therefore, it was concluded that the use of trash fish (halfbeak and scalloped perchlet) is effective as a feed for the growth and survival of the Mangrove Red Snapper

Abstract:

The population dynamics of juvenile snapper, Pagrus auratus, were investigated in the Hauraki Gulf, north-eastern New Zealand, between 1982 and 1990. Attention focused on age and growth, temporal and spatial variation in abundance, and recruitment. Daily increment formation was validated in the sagittae of snapper up to about 160 days old. Increment width varied with time of year, and snapper age, and increments were not resolvable with a light microscope during winter. Increment counts inside a prominent metamorphic mark showed that larval duration was 18-32 days, and was inversely related to water temperature. Spawning dates were back-calculated from increment counts in settled juveniles, and ranged from September to March with a peak in November-January. The onset of spawning was temperature dependent. Fast-growing snapper had smaller sagittae than slow-growing snapper, indicating an uncoupling of otolith and somatic growth. Snapper gonads differentiated first as ovaries during the second year of life, and then some juveniles changed sex to become males during their third year. Sex change occurred before maturity, so snapper are functionally gonochoristic. Growth was slow during the larval phase, but increased rapidly after metamorphosis to about 0.6-0.9 mm.day-1. From the first winter, growth followed a well-defined annual cycle, with little or no growth during winter, and linear growth of 0.16-0.43 mm.day-1 during spring-autumn for 0+/1+ and 1+/2+ snapper. Snapper grew faster at higher temperatures. Trawl catch rates were affected by numerous gear and environmental factors, but probably provided reasonable estimates of snapper relative abundance. Recommendations are made for improving snapper trawl survey procedures. There was a strong annual abundance cycle in the Kawau region, peaking in spring, and declining to a minimum in winter. Snapper were patchily distributed at a spatial scale of 1-2 km, probably because of preference for specific micro-habitats. Year class strength of 1+ snapper varied 17-fold over seven years, and was strongly positively correlated with autumn sea surface temperature during the 0+ year. The strengths of the 1991 and 1992 year classes are predicted to be below average, and extremely weak, respectively.

Abstract:

It is important for consumers to be aware of the source of gelatin due to religious restrictions, as pork is forbidden for consumption by Muslims and Jews, and cows are forbidden for consumption by Hindus. Fishery waste, such as fish bones and scales, can be a promising alternative raw material for gelatin production, as they are halal for consumption. The process of gelatin preparation involves several stages, including pretreatment, degreasing, demineralization, and hydrolysis using bromelain enzyme. hydrolysis process using bromelain enzyme ranging from 1, 2, 3, 4, 5, 6 and 7% at 300 rpm and temperature 55 °C. Hydrolysis was carried out for 6 hours and 9 hours for each concentration. Characterizations of gelatin was conducted for pH, water content, ash content, Fourier Transform-Infrared Analyzer (FTIR), X-ray Fluorescence (XRF) Spectrometry and Gas chromatography (GC). Based on the research, the optimum conditions for produce halal gelatin from red snapper scales was obtained at 5% bromelain enzyme for 9 hours for hydrolized collagen to gelatin with a yield of 11.414%, pH of 5.3, water content of 7%, ash content of 2.1%, and free from alcohol and heavy metals. The FTIR spectra show that the absorption at wavenumber 2944.5, 1628.74, 1524.55, and 1332.14 cm-1 respectively, indicating the presence of C–H, C=O, C=C and C–N stretching. The presence of absorption peaks of that functional groups show gelatin has been formed. XRF analysis show the absence of heavy metals as Hg, Pb, Cd, and Zn. Fish-based gelatin in this study is produced through a halal process, using halal ingredients, and its product does not contain alcohol, thus the gelatin produced in this study is a halal product.

Abstract:

There is a direct correlation between successful metamorphosis from larvae to post-larvae and the quality of the resultant juveniles or fry. Juvenile quality, in turn, is a major factor influencing fish production level and market price. However, following the profound morphological and physiological changes occurring during metamorphosis, the emerging juveniles in some species characteristically demonstrate heterotrophic growth, poor pigmentation, cannibalism and generally poor survival. The white grouper (Epinephelus aeneus) in Israel and the Pacific threadfin (Polydactylussexfilis) in Hawaii are two promising candidates for mariculture that have high market value but a natural fishery that has sharply declined in recent years. Unfortunately, their potential for culture is severely hampered by variable metamorphic success limiting their production. The main objective was to compare the efficacy and economic viability of dietary or environmental iodine on metamorphic success and juvenile quality in the white grouper and the pink snapper which would lead to improved commercial rearing protocols and increased production of these species both in Israel and the US. The Hawaii Institute of Marine Biology encountered problems with the availability of pink snapper brood stock and larvae and changed to Pacific threadfin or moi which is rapidly becoming a premier aquaculture species in Hawaii and throughout the Indo-Pacific. The white grouper brood stock at the National Center for Mariculture was lost as a result of a viral outbreak following the sudden breakdown of the ozone purification system. In addition, the NCM suffered a devastating fire in the fall of 2007 that completely destroyed the hatchery and laboratory facilities although the BARD project samples were saved. Nevertheless, by studying alternate species a number of valuable findings and conclusions that can contribute to improved metamorphosis in commercially valuable marine species resulted from this collaborative effort. The Israeli group found that exposing white grouper larvae to external TH levels synchronized and increased the rate of metamorphosis. This suggested that sub-optimal synthesis of TH may be a major factor causing size heterogeneity in the larval population and high mortality through cannibalism by their larger more metamorphosed cohorts. Two protocols were developed to enrich the larvae with higher levels of the TH precursor, iodine; feeding iodine enriched Artemia or increasing the level of seawater iodine the larvae are exposed to. Results of accumulated iodine in gilthead seabream larvae indicated that the absorption of iodine from the water is markedly more efficient than feeding iodine enriched Artemia nauplii. Samples for TH, which will be analyzed shortly, will be able to determine if another dietary factor is lacking to effectively utilize surplus tissue iodine for TH synthesis. Moreover, these samples will also clarify which approach to enriching larvae with iodine, through the live food or exposure to iodine enriched seawater is the most efficient and cost effective. The American group found that moi larvae reared in ocean water, which possessed substantially higher iodine levels than those found in seawater well water, grew significantly larger, and showed increased survival compared with well water reared larvae. Larvae reared in ocean water also progressed more rapidly through developmental stages than those in low-iodine well seawater. In collaboration with Israeli counterparts, a highly specific and precise radioimmunoassay procedure for thyroid hormones and cortisol was developed. Taken altogether, the combined Hawaiian and Israeli collaborative research suggests that for teleost species of commercial value, adequate levels of environmental iodine are more determinate in metamorphosis than iodine levels in the live zooplankton food provided to the larvae. Insuring sufficiently high enough iodine in the ambient seawater offers a much more economical solution to improved metamorphosis than enriching the live food with costly liposomes incorporating iodine rich oils.

STUDY ON FLEXURAL CAPACITY OF PROFILED STEEL SHEET - POLYURETHANE SANDWICH SLABS. The Hong Kong Institute of Steel Construction, March 2024. http://dx.doi.org/10.18057/ijasc.2024.20.1.6.

Abstract:

Widely employed in enveloped structures, the metal-faced sandwich panel boasts thermal insulation, noise abatement, lightweight, and remarkable assembly efficiency. In this paper, a new type of profiled steel sheet and polyurethane sandwich slab (PSSPSS) was proposed. Through static load tests and numerical simulations, the flexural properties of the PSSPSS were studied, and the influence of individual geometric parameters on the flexural capacity of the structure was evaluated. The results of this analysis led to the derivation of the calculation formulas for the deflection and flexural bearing capacity of the PSSPSS. These results demonstrate that the bearing capacity and failure mode of the structure, as determined by test and simulation, are in perfect agreement. The sandwich slab’s failure is mainly demonstrated by an overabundance of deflection, with the peak being 1/42 of the span, and the channel steel at the middle span being distorted and snapped. The slab deflection calculation formula’s results, when compared to the test results, demonstrate a mere 2.1% error, thus confirming its accuracy. The slab thickness, profiled steel sheet thickness, polyurethane foam density, and slab span all contribute to higher bearing capacity and improved stiffness in the structure, yet the effect of the slab span is more evident. The slab span, however, has a more profound effect on stiffness. The flexural bearing capacity formula’s applicability is indicated by the maximum error being within 10%, as demonstrated by the comparison of the formula’s results with the FEA results for the sandwich slab with varying parameters.
