Bakırçay River, which carries agricultural drainage and polluted wastewater with high nitrogen and phosphorus content, is polluted due to domestic and agricultural resources. The water of the Bakırçay River is used for irrigation in agriculture and fishing from the dam lakes on the river for feeding purposes also negatively affects the health of the people in the vicinity. In the Bakırçay River, there is widespread pollution caused by mining areas as well as domestic, industrial and agricultural pollution. For this purpose, the “Algal Growth Inhibition Test, OECD 201” was applied to the water samples obtained from 10 stations on the Bakırçay River. Scenedesmus dimorphus (Turpin) Kützing, 1834 green algae culture, accepted as the primary trophic level representative for the \" Algal Growth Inhibition Test, OECD 201\" test, one of the short-term phytotoxicity test methods, was used in this test. Water samples were tested at five different dilutions (40, 60, 80, 100 %). To determine the effects on the growth of Scenedesmus dimorphus, the cells were counted by fluorimeter (Turner design) daily at the same time and the test duration was 72 hours. In conclusion, the highest level of toxicity was found at Stations 1, 9, 10,13,14, and 15. The reason for this was that there was a coal facility near Station 9 and that all branches of the Bakırçay River joined near Station15 and then drained into Çandarlı Bay.","PeriodicalId":11439,"journal":{"name":"Ege Journal of Fisheries and Aquatic Sciences","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73137101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effect of this change in sea cucumber stocks in Türkiye started to be seen after the 2010s. To address it, we carried out a study to compare the population density of the most caught Holothuria tubulosa and Holothuria polii species between exploited and non-exploited areas in the Aegean Sea coast of Türkiye. The study was carried out between September 2018 and March 2020 at 4 stations, two of which are in Çandarlı Bay, where sea cucumber fishing is free, and two in İzmir Bay, where it is prohibited. Samplings between 0-20 m depths were carried out with underwater transect line technique, and at depths deeper than 20 m, with beam trawling operations. A total of 6 sea cucumber species were identified, including Holothuria mammata, Holothuria sanctori, Parastichopus regalis and Holothuria forskali species, apart from the target species H. tubulosa and H. polii. Only one P. regalis individual was recorded in the samplings in waters deeper than 20 m. The mean densities of H. tubulosa and H. polii were found to be higher in İzmir Bay stations than in Çandarlı Bay (p<0.05). The results of this study clearly reveal that the population density of sea cucumber in sampling areas has decreased tens of times compared to the last 5 years.","PeriodicalId":11439,"journal":{"name":"Ege Journal of Fisheries and Aquatic Sciences","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84132311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This situation highlights the need for the effective treatment of wastewater in sustainable aquaculture. Today, instead of traditional physical and chemical methods in the treatment of wastewater originating from aquaculture, ecosystem-sensitive and by-product-oriented systems have begun to be adopted. The main principle of the zero-waste approach is the recycling of the nutrients in the wastewater to produce another food. In this new innovative approach, the production of other organisms from the different trophic levels using the wastewater of aquaculture in the integrated multi-trophic systems (such as aquaponics) is possible to recycle the nutrients. It has been considered the integrated multi-trophic systems (IMTA) more valuable as these systems can be used both in environment-friendly wastewater treatment and in the conversion of nutrients in wastewater to biomass. The nutrients such as nitrogen and phosphorus in aquaculture wastewater can be utilized to produce two organisms (i.e. fish+mussel) or three organisms (i.e. fish+mussel+seaweed) through IMTA. Aquaculture wastewater can be used to reduce the nutrients in constructed wetlands and plant lagoons representing the reasonable approach for sustainable aquaculture and wastewater treatment. \u0000Here, the innovative approach to sustainable aquaculture wastewater treatment was reviewed for the current and innovative technologies. It was emphasized that the need for environment-friendly wastewater treatment Technologies such as aquaponics, enlargement of constructed wetlands, or increase in using the integrated multi-trophic production systems (IMTA) in practice are recommended for sustainable aquaculture.","PeriodicalId":11439,"journal":{"name":"Ege Journal of Fisheries and Aquatic Sciences","volume":"83 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83798990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The marination ratios and times were as follows: (10:90; 90:10; 50:50; 100:100/100 g squid ring) and (1, 3, 6, 12, 24, 48 and 72 h), respectively. The effects of marination ratios and times on the microbiological and sensory changes of the cooked squid rings were observed at 4°C. Pathogenic bacteria (Vibrio spp., Staphylococcus aureus and Escherichia coli) were not found in the cooked (C) and cooked marinated (CM) squid rings in the present study. The TMC (total mesophilic aerobic bacteria counts) of all groups were determined as consumable at 72 h, whereas the TMC of C and CM samples (C7, CM7, CM14, CM21, CM28) increased to 5.92, 5.83, 5.71, 5.57 and 5.42 log cfu/g, respectively. Regression models were created to estimate the TMC and lactic acid bacteria count (LBC) of cooked squid rings during the marination process at 4°C to determine the increasing rates of bacterial growth of samples. As a result of this study; when compared with Model I and Model II; both of them can be preferred for predicting the TMC of C and CM samples. The variability in the TMC of C and CM squid samples was obtained as 93% in Model I, whereas the variability in the TMC of these samples was observed as 91% in Model II. So, these two models performed well, and they can be used for predicting the TMC of C and CM samples. Additionally, Model III was also developed for estimating the prediction value of LBC of cooked squid samples during the marination process at 4°C. This model was also determined very good performance (86%) to estimate the predicting values of LBC and it can be very essential together used with Model I or Model II for marinated fishery products to estimate the real shelf-life.","PeriodicalId":11439,"journal":{"name":"Ege Journal of Fisheries and Aquatic Sciences","volume":"36 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91501601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
