This study aims to review and update the species diversity of nemipterids along the north-eastern coast of India, particularly Odisha, and provide a simple key for easy identification. An ichthyofaunal survey piloted during 2017 – 2020 along the Odisha coast confirmed the occurrence of seven valid species of nemipterids namely, Nemipterus bipunctatus (Valenciennes, 1830), N. japonicus (Bloch, 1791), N. nematophorus (Bleeker, 1854), N. peronii (Valenciennes, 1830), N. randalli Russell, 1986, Parascolopsis aspinosa (Rao & Rao, 1981), and Scolopsis vosmeri (Bloch, 1792), adding four species to the previously annotated checklist of 2007. The present paper reports the first record of four species namely, N. nematophorus , N. peronii , N. randalli , and P. aspinosa from the Odisha coast in the Bay of Bengal. Based on the findings of the present study and available literature, a key to the reported and identified species of the family Nemipteridae from the Odisha coast was developed with a detailed description of taxonomic characters for easy identification.","PeriodicalId":51062,"journal":{"name":"Indian Journal of Geo-Marine Sciences","volume":"59 4 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88067129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Capture fisheries contribute a comparatively vital role to the national economy. However, poverty, environmental degradation and political instability are major problems for the Pakistani people, and no effective steps have been taken to handle this socio-economically important sector efficiently in the past. Furthermore, the fisheries sector faced its own set of challenges, including the emergence of small-scale artisanal fisheries, the nonexistence of technologies, deficiency of institutional development, an absence of infrastructure, insufficient human resource skill, and a lack of responsiveness among fishing societies, all of which contributed to the sector's demise. The National Fisheries Policy (NFP) was formulated to address these problems in the fisheries sector. Potential efforts have been made by the Government of Pakistan to solve these constraints under various plans of objectives and strategy axes of the policy. Our findings indicate that despite these efforts, the fisheries sector does not show significant growth to achieve the policy goals. So, it is necessary to re-evaluate and re-orient this policy for further development of this sector. It is also essential to achieve the aim of Government of Pakistan Vision 2025 to become one of the 25 th largest economies in the world.","PeriodicalId":51062,"journal":{"name":"Indian Journal of Geo-Marine Sciences","volume":"5 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86351142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aluterus monoceros forms an important fishery in the northern Indian Ocean; however, information on its population dynamics is sparse, as the species has not been explicitly studied. This study elucidates the population parameters from 1031 individuals landed in the multi-day trawl fishery along the western Bay of Bengal from January 2017 to December 2019. Total length ranged from 21.5 to 64.4 cm with a mean of 47.54 cm. Von Bertalanffy growth equation was L t = 67.67 [1 – e –0.32 (t + 0.0592) ]. The fishery was dominated by 3 and 4-year-old age classes and the estimated lifespan was 9.32 years. Recruitment was observed throughout the year and was bimodal, with the major pulse from October – February and the minor pulse from April – June producing 52.44 % and 36.24 %, respectively of the annual recruits. Natural mortality, fishing mortality and total mortality per year were 0.66, 0.55 and 1.21, respectively. Exploitation ratio was 0.45 and exploitation rate was 0.32. Though the species is currently underexploited, considering their lower capture sizes and their occurrence as by-catch in the trawl fishery, precautionary approach is suggested with management measures targeted at protecting their early life history stages.","PeriodicalId":51062,"journal":{"name":"Indian Journal of Geo-Marine Sciences","volume":"39 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88950777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
