The north-eastern coast of India is rich in marine floral and faunal biodiversity, yet relatively less studied. 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.
印度东北海岸拥有丰富的海洋植物和动物生物多样性，但研究相对较少。本研究旨在回顾和更新印度东北部沿海，特别是奥里萨邦的蛇足类物种多样性，并提供一个简单的识别钥匙。2017 - 2020年在奥里萨邦沿海进行的鱼类调查证实了7种有效的线虫属物种的存在，即双刺线虫(Nemipterus bipunctatus, valciennes, 1830)， N. japonicus (Bloch, 1791)， N. nematophorus (Bleeker, 1854)， N. peronii (valciennes, 1830)， N. randalli Russell, 1986, aspinosa Parascolopsis (Rao & Rao, 1981)和Scolopsis vosmeri (Bloch, 1792)，在2007年之前注释的清单中增加了4种。本文报道了在孟加拉湾奥里萨邦海岸首次记录到的N. nematophorus、N. peronii、N. randalli和P. aspinosa四种。根据本研究结果和文献资料，编制了印度奥里萨邦(Odisha)沿海已报道和鉴定的Nemipteridae科昆虫分类目录，并详细描述了分类特征，以方便鉴定。

Pakistan is endowed with abundant fisheries resources that have significant economic potential. 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.

The present study reveals the first documented distribution record of Desmodema polystictum (Ogilby, 1898) from the Andaman coast, eastern Indian Ocean. The species is rare in nature and the knowledge regarding the taxonomy, ecology and distribution is still limited. Only few records have been come from the Indian Ocean. The study is based on a single specimen (34 cm total length) collected from the northeastern region of Andaman Islands, India. The present record of D. polystictum from Andaman waters provides greater latitude and depth distribution than previously acknowledged from the Indian Exclusive Economic zone. Along with the comparative morphometric and meristic data from previous reports, description of present specimen as well as distributional information are also provided and discussed.

The nature of tsunamigenic and palaeo-tsunamigenic sediments in Neil Island, deposited by the great Indian Ocean in 2004 is documented herein. Pit, trench and core samples were collected from the four beaches, namely, Bharatpur, Ramnagar, Sitapur and Lakshmanpur; which exhibit distinguished anomalies in the sedimentological parameters, viz . skewness, kurtosis and standard deviation at various depths. The palaeontological study shows the simultaneous occurrence of characteristic benthic taxa of near-shore environment and upper part of continental slope along with the open ocean dweller planktic foraminifera- an intermixed foraminiferal assemblage is mainly due to the tsunami wave actions. The multiproxy approach reveals the occurrence of the tsunami and palaeo-tsunami deposits in Neil Island from 9 to 40 cm and below 60 cm depth, respectively.

Information on age and growth for monocanthid species globally is limited. 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.
