The influence of the sea temperature on the development of individuals is considered. It is shown that with an increase in the average annual water temperature, the average annual length (correlation coefficient r = 0.97), weight (r = 0.96) and condition factor (r = 0.93) of individuals increase. It was found that red mullet has a positive allometric growth in the study area. The analysis showed that there was a close correlation between changes in the average annual temperature and the allometric growth rate b (r = 0.97). The equations of length growth of M. barbatus ponticus showed retarded linear growth of the fish living on the south-western shelf of the Crimea in comparison with other areas, Sinop region (Black Sea) and the Aegean Sea.

The present study aims to explore whether triclosan at environmentally relevant and sublethal concentrations could influence the reproductive physiology of the fish Anabas testudineus in the spawning phase. Fish were exposed to triclosan at environmentally relevant (0.009 and 9 µg L−1) and sublethal (176.7 µg L−1) concentrations for 4, 7, 30 and 60 d during the spawning phase for evaluating the reproductive potential of the fish. Triclosan exposure caused a significant (P<0.05) reduction in the level of total protein in gonads and liver tissues while increasing blood plasma to meet the energy demand and overcome metabolic stress. Impairment in gonadal steroidogenesis was evidenced by the reduction in the activities of 3β- and 17β-hydroxysteroid dehydrogenases associated with alteration in the levels of serum gonadotropins, sex steroid hormones and vitellogenin. Triclosan exposure caused a reduction in the rate of fecundity in females and declined sperm counts, motility and viability in males. Histological lesions in gonadal tissues further confirmed the reproductive toxicity of triclosan, which in turn could contribute to the reproductive failure of the fish.","PeriodicalId":38161,"journal":{"name":"Ribarstvo, Croatian Journal of Fisheries","volume":"80 1","pages":"47 - 66"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45775724","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 reefs are under increasing pressure from the development of underwater tourist activities so it is necessary to pay attention to the reef condition to maintain its sustainability. This study was conducted in September 2019 by examining the condition of coral reefs in the most visited snorkeling spots based on information from tour operators, i.e. the Ujung Bintang, Maer and Karang Sendok spots. Data was collected using a 20 m line belt transect to count coral cover and was analyzed using coral morphology triangles to assess the Coral Condition Index (CCI) and Impact Severity Index (ISI). The condition of coral reef cover at the Ujung Bintang and Maer spots were in the “good” category based on the CCI, while at the Karang Sendok spot the corals were in the “bad” category based on the ISI. The three snorkeling spots have competition-adapted (K) morphology, which means that the coral reefs are dominated by non-Acropora corals associated with coral reefs with high waves. The dominant life form at the Ujung Bintang spot was foliose corals, at the Maer spot, it was foliose coral and non-Acropora branching corals, while at the Karang Sendok it was Acropora, which is more vulnerable than foliose and massive corals. The CCI at the three spots was in the “good” category as there are healthy coral colonies, whereas the ISI was in the “poor” category since partially and recently dead coral colonies were found there. The coral colony damage in the spots was dominated by bleached coral colonies and partially dead coral colonies.","PeriodicalId":38161,"journal":{"name":"Ribarstvo, Croatian Journal of Fisheries","volume":"80 1","pages":"77 - 86"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44240682","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}

Although both species are considered critically endangered in the Adriatic and the rest of the world, there are almost no data on the current status of populations, threat assessment and species-specific in-situ conservation. Common angel shark is still present in highly fragmented areas of the eastern Adriatic with extremely rare but consistent records, while smoothback angel shark is mostly considered regionally extinct in the Adriatic due to overfishing and overuse of non-selective fishing gear. There have been only 3 published records of common angel shark this century, the last two of which were reported by fishermen. This paper presents data on 34 new finds, including neonates, juveniles, subadults and adults recorded between January 2020 and August 2021 in the Zadar-Šibenik archipelago (central Adriatic) and one in Premantura (northern Adriatic). Two are original findings during the field expedition, 9 were reported directly by local fishermen, while 23 were reported through a detailed questionnaire.

Compared to the central and northern areas, the southern part of the Adriatic Sea, specifically the Albanian coast, has been less studied. The aim of this study is to evaluate the prevalence of new/non-native fish species on the north Albanian coast in order to provide the first data on their presence. Data collection was carried out from March to August 2019 using LEK (Local Ecological Knowledge) protocol in five different locations along the northern part of the Albanian coast. The research followed a predefined methodology previously successfully applied in different countries of the Mediterranean basin by using a semi-structured questionnaire. During this study, 9 new and non-native species were recognized by the fishers, while only 5 of them have shown an evident abundance increase based on their respective catches in recent years. Results suggest that some of the analyzed species, such as blue crab Callinectes sapidus and bluefish Pomatomus saltatrix, represent important members of the fish fauna in north Albania coastal waters (including the lagoons). Future studies regarding the assessment of their impact and management strategies are highly recommended.","PeriodicalId":38161,"journal":{"name":"Ribarstvo, Croatian Journal of Fisheries","volume":"80 1","pages":"17 - 25"},"PeriodicalIF":0.0,"publicationDate":"2022-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49396845","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}

Iskenderun Bay, comprising the Samandağ coast in Turkey, is the most important introduction pathway of alien species in the northeastern Mediterranean. In this study, the density, abundance, distribution and interaction of invasive lionfish or devil firefish Pterois miles were assessed using the UVC method on the Samandağ coast. The total transect area monitored on the Samandağ coast was 4.500 m2. Species richness, Shannon’s diversity index and rate of biomass were 25, 1.81 and 73.5 m2, respectively. Reduced diversity was observed with increasing depths. The sandy seafloor was a limiting factor for lionfish distribution. There was a significant positive correlation between lionfish total density and both the Shannon diversity index (r = 0.99, P<0.001) and Shannon evenness index (r = 0.99, P<0.05). A high number of significant positive correlations (P<0.05) were detected between the occurrence of lionfish and the occurrence of both the native species and other alien species. The first stock assessment study of lionfish by the UVC method in Turkish marine waters revealed that native species are under very high pressure from lionfish species, especially Chromis, Sparids and Wrasses, indicating negative effects of lionfish on regional native biodiversity.","PeriodicalId":38161,"journal":{"name":"Ribarstvo, Croatian Journal of Fisheries","volume":"80 1","pages":"38 - 46"},"PeriodicalIF":0.0,"publicationDate":"2022-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43812107","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}

At the same time, the demand for organic food is increasing in the modern market. Although fruits, vegetables and nuts have the biggest share in the organic food market in Europe, the aquaculture production of organic fish is also growing. Therefore, the main aim of this study is to explore the knowledge and perception of Croatian consumers about fresh fish from organic farming. An online and face-to-face survey was conducted on a sample of 303 respondents. Data analysis (univariate and bivariate) was performed using SPSS Statistics for Windows. Most consumers have medium and low subjective knowledge about fresh fish from organic farming, and objective knowledge about fresh fish from organic farming is low. Only half of the consumers are aware that they can buy fresh fish from organic farming in the domestic market. Half of the consumers have already consumed fresh organic fish, and half are willing to pay a higher price for fresh fish from organic farming. Compared to fresh fish from conventional farming, respondents consider fresh organic fish to be healthier, tastier and to have less fat, but also more expensive and less available.","PeriodicalId":38161,"journal":{"name":"Ribarstvo, Croatian Journal of Fisheries","volume":"80 1","pages":"7 - 16"},"PeriodicalIF":0.0,"publicationDate":"2022-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41437315","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}
