The algae were grown in N free medium (N − ) in order to study the proximate composition via the determination of protein, lipid and carbohydrate. The chemical constituents of this algae were determined using GC-MS and mineral content was analysed using Inductive Coupled Plasma-Mass Spectrometry (ICP-MS). From the results, the proximate analysis showed increased lipid (34.77 ± 0.6%), followed by carbohydrate (26.21 ± 0.2%) and protein (5.4% dry weight). The chemical constituents of C. salina were successively extracted with diethyl ether, hexane, chloroform, acetone and methanol. The extract percentage varied greatly between various solvents, with the highest one (4.68%) recorded for methanol. A total of 35 compounds were identified from the extracts and the identified chemical groups included ketones, terpenes, fatty acids (FA), fatty alcohols and esters derived fatty acids and/or dicarboxylic acid and hydrocarbons. The methanol extract consisted of FA (35%), amino acids and N-containing metabolites (7%), fatty alcohols (8%), organic acids (3%) and hydrocarbons (80%). The algae exhibited high amounts of Mg (54.079 mg/50 g) followed by C (17.341 mg/50 g), S (5.702 mg/50 g) and Na (3.275 mg/50 g). These results demonstrated a strong correlation between the nitrogen content and lipid accumulation, hence showing that Chlorella salina could serve as a potential candidate for biodiesel production.","PeriodicalId":18195,"journal":{"name":"Marine Biology Research","volume":"18 1","pages":"307 - 314"},"PeriodicalIF":1.1,"publicationDate":"2022-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46662369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rapana venosa is harvested along the entire coast of the Black Sea using dredging or beam-trawl fishing. This study adopted the cover net method to assess the composition and proportion of non-target escapees in Rapana fisheries by dredging along the western coast of the Black Sea. In this method, the dredge net bag (codend net) is covered with a second net bag that has a smaller mesh size to retain those individuals escaping from the dredge net bag. Up to 87% of the total ∼1.4×106 individuals per km (ind. km−2) cover net catches belonged to non-target species. Overall, 24 non-target species were caught in the cover net, with 46% of species belonging to the Teleostei (mostly flatfishes), 21% Malacostraca, 17% Bivalvia, 8% Gastropoda, 4% Amphibia, and 4% Ascidiacea. On the other hand, up to 6.8% of the total ∼0.16×106 ind. km−2 catches of the codend net (dredge net) belonged to non-target species. Compared to the cover net, a total of seven non-target species were retained in the codend net, and six of them belonged to Bivalvia. This study demonstrated an apparent negative impact of Rapana fisheries, particularly on escapees that often go unaccounted for their vulnerability to stress and physical damage.","PeriodicalId":18195,"journal":{"name":"Marine Biology Research","volume":"18 1","pages":"347 - 360"},"PeriodicalIF":1.1,"publicationDate":"2022-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48067239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the damage and mortality rates of the species that entered the tested fishing gear were determined to understand whether the tested fishing gear has a possible negative effect on benthic species. In the grid-net design, a rectangular metallic grid positioned 6 cm off the ground substituted half of the codend to allow the escape of discard species. Sea trials were carried out in the south-eastern Black Sea between 13 and 24 October 2021. Results showed that the discarded catch amount was significantly reduced by each GND (P < 0.05). Compared with the commercial fishing gear, the reductions in the discarded catch amounts (in terms of number) were 91.6%, 92.2%, and 95.0% for 22, 25, and 28 mm GNDs, respectively. The minimum commercial product loss was determined at 22 mm GND. In addition, it was seen that each GND compared to commercial gear caused statistically significantly less damage and mortality on the discarded species. In conclusion, 22 mm GND was the most successful design among the tested gears in minimizing commercial product loss and reducing the discarded catch amount. Recommendations are given for this design to be adopted by the commercial fleet.","PeriodicalId":18195,"journal":{"name":"Marine Biology Research","volume":"18 1","pages":"335 - 346"},"PeriodicalIF":1.1,"publicationDate":"2022-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44196853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We counted 233 species dominated by diatoms (126 species) and dinoflagellates (97 species). The most common diatom species were Leptocylindrus danicus and Rhizosolenia styliformus, while Scrippsiella sp. was the most common dinoflagellate species. The richness and relative abundance of diatoms were greater during the spring of 2014–2015 and the winter of 2015 and present an increasing north–south gradient. However, those of dinoflagellates were greater during the summer and autumn seasons of the years 2014–2015 and the winter of 2016, with a decreasing north–south gradient. This could be mainly related to the difference between the requirements of these two groups and the spatiotemporal variability of the physicochemical characteristics of the waters governed by seasonal and inter-annual variations of the currents, by the floods and by the morphology of the coast in this area. Indeed, the increase in the richness and abundance of dinoflagellates coincides with the increase in temperature, transparency and the decrease in the concentration of nutrient salts in the environment. However, the increase in nutrient content, the decrease in temperature and transparency favours diatoms compared with dinoflagellates.","PeriodicalId":18195,"journal":{"name":"Marine Biology Research","volume":"18 1","pages":"203 - 214"},"PeriodicalIF":1.1,"publicationDate":"2022-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47434309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
