Comparison of Nutrition Values of Discarded Fish By Bottom Trawl Fishing in the Mersin Bay

In the present study, proximate composition and meat yield of discarded fish Tub gurnard (Chelidonichthys lucerna Linnaeus, 1758), brown comber(Serranus hepatus Linnaeus, 1758) and Scaldfish (Arnoglosus laterna Walbaum, 1792) caught in Mersin Bay (Northeastern Mediterranean) by bottom trawlers were investigated. The highest protein values and the lowest total lipid and ash values were recorded during spring in three species (P<0.05). Meat yield was found to be different significantly among spring and autumn samples (P<0.05). Mean meat yield of tub gurnard, brown comber and scaldfish were 50.94%, 53.85% and 64.56%, respectively. Results of study show that although these species are considered to be discarded, they can be considered as food or additive for various living groups due to their high nutritional quality, thus they can contribute significantly to the food requirement and economy of the country. Thus, both the ecological balance in the marine environment will be protected and economic losses will be prevented.

Demak is a coastal area on the North Coast of Java with a large enough potential for demersal fish resources. This research aimed to determine the composition, the length and weight distribution, and catch per unit effort (CPUE) of demersal fish caught using mini bottom trawl at the north coast of Demak Regency. The research was carried out in October-December 2020 by observation of ten trips of mini bottom trawl fishing. Each fish captured was then grouped by type, identified, and measured its length and weight. The result showed that 38 species consist of 31 fishes, four mollusks, and three crustaceans. The fish captured dominated by pony fish (Leiognathus equulus) as much as 31.23% and largehead hairtail (Trichiurus lepturus) of 23.52%. The catch per unit effort (CPUE) average of mini bottom trawl was 44.77 kg/trip. Mainly fish (more than 95%) caught in small size compared it’s the maximum attainable length (L-max), with all the weight ranges from 0.3 to 520 g and more than 98% sized 0.3-80 g. Mini bottom trawl catches many types of fish and small size; therefore, mini bottom trawl is classified as a type of fishing gear with a very low selectivity level.

Purpose The purpose of this paper is to examine the performance of a fastener composite coating system, sherardized (SD) coating/zinc-aluminum (ZA) coating whether it has good performance in marine environment. Design/methodology/approach In this paper, SD coating was fabricated on fastener surface by solid-diffusion method. ZA coating was fabricated by thermal sintering method. Corrosion behaviours of the composite coating were investigated with potentiodynamic polarization curves, open circuit potential and electrochemical impedance spectroscopy methods. Findings Neutral salt spray (NSS) and deep sea exposure tests revealed that the composite coating had excellent corrosion resistance. Polarization curve tests showed that corrosion current density of the sample with composite coating was significantly decreased, indicating an effective corrosion protection of the composite coating. OCP measurement of the sample in NaCl solution demonstrated that the composite coating had the best cathodic protection effect. The good corrosion resistance of the composite coating was obtained by the synergy of SD and ZA coating. Practical implications SD/ZA coating can be used in marine environment to prolong the life of carbon steel fastener. Social implications SD/ZA composite coating can reduce the risk and accident caused by failed fastener, avoid huge economic losses. Originality/value A new kind of composite coating was explored to protect the carbon steel fastener in marine environment. And the composite coating has the long-term anti-corrosion performance both in simulated and marine environment test.

An experiment was conducted for evaluation of proximate composition of 25 pigeon pea genotypes (Cajanus cajan L.)”differing in colour. The analysis revealed significant differences in the content of moisture (7.04-12.09%); crude protein (17.62- 25.45%); crude fat (1.41-2.93%); carbohydrate, (49.68-60.48) and ash (3.05-5.00%). Limiting amino acids viz tryptophan and methionine were ranged from 0.56-1.03 and 0.70-1.16 g/16g N respectively. The genotype PT-012-16 was found to be high in protein (25.45%), whereas the genotype PT-04-391 recorded the highest fat (2.93%). The higher tryptophan was observed in genotype PT-012-26 (1.03 g/16g N) whereas highest methionine content was recorded in PT-012-6 (1.16 g/16g N). All genotypes under study were found to be deficient in both the limiting amino acids tryptophan and methionine when compared with the WHO/FAO reference standard. This study revealed that the genotypes PT-012-9, PT-012-16 and PT-012-23 were found to be promising for future breeding programme for nutritional quality improvement.

The proximate composition and fatty acid profile of five tissues (head, skin, bones, muscle and liver) of juvenile Siganus guttatus fed with Enteromorpha prolifera were investigated. The results indicated that: (1) The content of protein and fat among these five tissues showed a significant differences (P Lass Than 0.05). The muscle has the highest content of protein and the lowest content of fat. (2) The highest content of fatty acid in SFA is 16:0 in all five tissues, the highest content of fatty acid in MUFA is18:1n-9c (cis) in skin, bones, muscle and liver, while the highest content of PUFA is DHA in muscle. Muscle contained the highest value of DHA and EPA, the total content was more than 100 times in bones. Muscle tissue is rich in many important polyunsaturated fatty acids such as EPA, DPA, DHA, ARA and ALA, which has better nutritional quality and immune and health function.

By Catch

The teleosts Chelidonichthys cuculus, Trigloporus lastoviza, Serranus cabrilla and Trachinus draco, are important by-catch species, in terms of landed biomass and commercial value, from the continental shelf bottom trawl fishery off the Balearic Islands (western Mediterranean). The main biological parameters of these species were calculated from monthly biological samplings, and were used along with three years pseudo-cohorts (2008-2010) obtained from monitoring on-board of the bottom trawl fleet, to assess their exploitation level through Virtual Population Analysis (VPA) and Yield per Recruit (Y/R) analysis. Time series of fishery independent indicators based on MEDITS surveys data such as the evolution of the abundance and biomass, the distribution range, and the Conservation Status of Fish b (CSFb), were also analyzed. All four species analyzed showed growth overfishing. The reductions of the fishing effort required to reach the Y/RF0,1 reference point were lower, 66-73% depending on the species, to those reported for the target species M. merluccius (87%), but higher than that reported for M. surmuletus (53%), in the study area in the period 2000-2010. The abundance and biomass, and the distribution range did not show any trend for the period 2001-2011, whereas the CSFb showed signs of recovery that may be due to the displacement of the trawl fishing effort from the shelf to the slope during the last decade. Our results underline the necessary incorporation of monitoring and assessment of by-catch species to the management of fisheries as their populations can show a more pronounced overexploitation than target ones.
