Twelve wild juvenile male were obtained from Kılıç Trout Fish Farm (Kahramanmaraş, Turkey). The juveniles were taken alive to the aquaria unit and stored in a 1000-liter capacity fiberglass tank. In order to identify the best size, age and testis structure of S.t. macrostigma for spermatogonial stem cell isolation and culture. Morphological and histological testis conditions were assessed. Fish were anesthetized with 0.04% 2-phenoxethanol. The surface of the fish was sterilized with 70% ethanol. Twelve fish were divided into two groups for enzyme digestion, and each group was divided into two replicates (three fish per replicate). Testis tissue of group one were digested by 0.25% trypsin- EDTA, and testis tissues of group two were digested by 0.05% trypsin-EDTA. At the end of the trial, first, the best age, size and weight of the male fish for spermatogonial stem cell isolation and culture were identified as 5+ month old, 12.13±1.5 cm, 19, 25±7.05 g respectively. Then, the highest spermatogonial stem cells were measured in the stage one and two of the testes. Finally, isolation and culture conditions were optimized for male S.t. macrostigma. Spermatogonial stem cell isolation and culture techniques were defined for fish in order to be used in surrogate reproduction technologies and gene transfer systems.","PeriodicalId":15784,"journal":{"name":"Journal of Fisheries and Aquatic Science","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89186489","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}

How crabs move in response to physical variables is important to management. We monitored life stages at canal control structures, assessed gender ratios with recreational crabbing, learned from crabbers, and studied movements of tagged crabs in a canal connecting Lake Mattamuskeet to the Pamlico sound. Juveniles enter the lake through two of 4 canals connecting to the sounds. Females migrate out through one canal. The lake standing population is about 70% male. Movements of 240 crabs in August 2012 and 102 crabs in October 2014 were quantified using RFID tags with co-located meteorological and oceanographic devices. Non-spawning females and males are nomadic. Crabs released in the canal move in response to changes in water depth and go with the flow, toward the Pamlico Sound (summer 76% and fall 78%). What crabbers describe as a fall migration appears to be concentration of crabs in warmer deeper canals and then southern movement with flow generated by strong north winds. To be effective, management strategies like migratory corridors require understanding of crab movements.","PeriodicalId":15784,"journal":{"name":"Journal of Fisheries and Aquatic Science","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90054423","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}

Calatagan Bay is a tourism, agriculture and aquaculture hotspot fronting the Verde Island Passage, touted to be the global center of marine biodiversity. Detection of stressors through monitoring is key in the proper management of the area. This study surveyed existing seaweed species of the coast, and contrasted it with reported species in the area together with fluctuations in sea surface temperatures for the past two decades, contrasted with the local knowledge and perspectives of local coast-dwellers. Seaweed along the coast were collected from a representative area of 50 km2 with species identification based on morphology and pigment. Nine species that were previously unreported were found while fourteen previously reported species were no longer observed. Caulerpa, Kappaphycus and Sargassum, all with known market demands, were the dominant genera. Sea surface temperature data from local weather stations and the NOMADs database indicate significant warming events from June 1998 to present, with peak sea surface temperature at 31.9oC. Focused group discussions with local communities indicate increased incidences of ice-ice disease, and issues with the uncontrolled use of fertilizers of neighboring farms contaminating their coastal fronts.","PeriodicalId":15784,"journal":{"name":"Journal of Fisheries and Aquatic Science","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74528370","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}

Four groups of ectoparasites viz. myxozoan, ciliophoran, monogenean and crustacean were recorded from a total 500 number of carp species like, Labeo rohita, Catla catla, Cirrhinus mrigala and Labeo calbasu collected from different ponds of selected blocks of South 24-Parganas district of West Bengal. The highest prevalence (64.8%) of infestation had been recorded by Myxozoans and the lowest was by Monogeneans (4.8%). The highest and lowest ectoparasitic prevalence in carp was observed in L. rohita (32.9%) and C. catla (27.3%). Beside these, lower temperature (Average 19.3oC), low pH (Average 6.9) and marginal level of dissolved oxygen (Average 6.0ppm) were also created an unfavorable condition for parasitic infestation during this season.
