This communication presents the results of the polymerase chain reaction (PCR) based surveillance of white spot virus (WSV) and monodon baculovirus (MBV) in shrimp culture systems of West Bengal, India. The WSV was detected in 14.87% of the total samples (N = 121) by first PCR and 16.53% of samples by nested PCR. The WSV infection was noticed in 12 of 65 Penaeus monodon, 6 of 39 Litopenaeus vannamei and 2 of 11 Macrobrachium rosenbergii samples. The MBV was detected in 8 of 65 P. monodon samples by non-nested PCR and all were also positive for WSV, thus indicating concurrent infection of shrimp. The results emphasized the need to observe strict quarantine measures during the seed selection to prevent the introduction of viral pathogens in grow-out systems.","PeriodicalId":55944,"journal":{"name":"Journal of Fisheries","volume":"26 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85023598","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}

Thousands of attractive fish species are traded annually. The tiger barb Puntius tetrazona is one of the most charming freshwater aquarium species worldwide. The present paper aimed at expanding the knowledge of the reproductive biology of this tropical fish. The ovary and the testis tissues of the tiger barb were embedded in paraffin following routine histological processes, stained with hematoxylin and eosin and Mallory’s trichrome techniques, and investigated by light microscopy. Histological examinations confirmed asynchronous-type ovaries resembling four different developmental stages including primary growth, cortical alveolar, vitellogenic and maturation. In the testis, primary spermatogonia, secondary spermatogonia, primary spermatocytes, secondary spermatocytes, spermatids and spermatozoa were identified. All oogenetic and spermatogenetic phases and mature germ cells occurred simultaneously in the tiger barb. This feature allows this tropical fish to breed rapidly and helps expanding its global trades.","PeriodicalId":55944,"journal":{"name":"Journal of Fisheries","volume":"4 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78899391","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 aim of this study is to reveal the microstructures of barbels and bony plates of S. laticeps, occurring in the Andaman Sea of Thailand, for the first time by using a scanning electron microscopy method. The chin barbels were characterised by a pebble-like surface whereas lip barbels resemble wooden texture. Taste bud-like organs were only visible in chin barbels. Bony plates from heads contained small semispheres around spine. In dorsolateral of posterior body, pits appeared at the apices, and semispherical buds were present in the middle and basal parts of tubercles. The study results may be important in understanding the physiology in peristediid fish.","PeriodicalId":55944,"journal":{"name":"Journal of Fisheries","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84794698","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}

To conserve hilsa, the government of Bangladesh has introduced fishing ban for certain periods of the year and also provides food assistance to hilsa fishers during the restriction period. Inadequate management often pushes real fishers out of the assistance programme and therefore, this study focused on assessing the effectiveness of the programme with a view to proposing a better management practice. A total of 202 randomly selected fishermen, living in the villages adjacent to Andharmanik River of Patuakhali district of Bangladesh, were interviewed. The Andharmanik River is famous for the natural breeding of hilsa. Results suggest that the amount of food provided and its distribution pattern were not that effective for the fishermen. Effectiveness was significantly related to the number of earning able family member, income difference between peak and restricted season and loan facility during the restriction period. This study also explained income difference trajectories of the fishermen community. Community-based management with facilitation by the state fisheries department and local government entity may enhance the programme effectiveness. More awareness programme and research are needed in this regard.","PeriodicalId":55944,"journal":{"name":"Journal of Fisheries","volume":"18 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85022508","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}
