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。

The present study emphasizes the forecast of Andhra Pradesh's total marine fish production and the catch of commercially important fishes, viz ., Indian Mackerel, Oil Sardine, Horse Mackerel, and Lesser Sardines for the next 5 years by different statistical and machine learning approaches under climate change scenario. Forecasting is done with and without the inclusion of climatic and environmental parameters in different models. Exogenous variables, i.e ., climatic parameters such as Sea Surface Temperature (SST), wind speed, and environmental parameters such as Chlorophyll- a , diffusion attenuation coefficient, and Photo-synthetically Active Radiation (PAR), were used in the model. The following models like Non-linear Autoregressive (NAR) Artificial Neural Network (ANN) (NNAR-ANN), Auto-Regressive Integrated Moving Average (ARIMA), Empirical Mode Decomposition based Artificial Neural Network (EMD-ANN), are used to predict the fish catch data using time series quarterly catch data of commercially important fishes and total fish catch without the inclusion of climatic and environmental variables. Auto Regressive Integrated Moving Average method with inclusion of exogenous variables (ARIMAX) and Non-Linear Auto Regression with exogenous variables (NARX) models were used to forecast along with quarterly average data of environmental and climatic variables. The model developed predicts the total fish catch and also the catch of commercially important fish for the next 20 quarters. The developed model forecasts are compared based on the error measure, i.e ., MAPE (Mean Absolute Percentage Error), and the results showed that the NARX model outperformed other models like ARIMAX, ARIMA, NNAR-ANN, and EMD-ANN. Implementation of management strategies considering the impact of climate change on fisheries will enhance sustainable fisheries and pave a pathway for the mitigation of climate change.

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.
