<b>A taxonomic study on trachypenaeid prawns with special reference to Indian records</b>
No full textBurkenroad created two subgenera of the genus Trachypenaeus viz., Trachypenaeus (Trachypenaeus) and Trachypenaeus (Trachysalambria) in 1934. These two subgenera were raised to the status of genus by Pérez Farfante and Kensley and simultaneously created two new genera for the group namely Megokris and Rimapenaeus. As such the trachypenaeid group of penaeid prawns consists of four valid genera namely Trachypenaeus, Trachysalambria, Megokris and Rimapenaeus. During the present study genus Megokris is being synonymised under its original genus Trachypenaeus. Therefore, the main objective of the present study is to propose a revision to the trachypenaeid group of penaeid prawn and to prepare a comprehensive document for the group recorded from Indian water. The study area represents genus Trachysalambria and Megokris with three species under each genus. </jats:p

A REVISION TO THE FRESHWATER FISH DIVERSITY OF PASCHIM MEDINIPUR AND JHARGRAM DISTRICT OF WEST BENGAL, INDIA
No full textIn the present contribution, an attempt has been made to provide a systematic classification of freshwater fishes of Paschim Medinipur and Jhargram Districts of West Bengal along with their human use and conservation status, as far as possible. Revision recognized 113 species of freshwater fishes (101 primary freshwater species, 12 secondary freshwater species), belonging to 12 orders, 32 families and 73 genera. Fourteen species of exotic fishes have been introduced to freshwater bodies of the Paschim Medinipur and Jhargram District. The top order with diverse species composition was Cypriniformes (45 species, 28 genera and 2 families). The most diverse family was Cyprinidae with 40 species and 25 genera. Freshwater fishes of Paschim Medinipur and Jhargram Districts revealed existence of 5 ornamental fishes, 63 food fishes and 46 were ornamental as well as food fishes. Out of the 113 freshwater fish species, 10.60% are under vulnerable or near threatened categories. Updated checklist will lead to a better understanding of the fish diversity of this area for conservation

A comparative review on freshwater fish fauna between West Bengal and Odisha, two middle-east Indian states
No full textThe objective of the present study is the comparative revision of inland freshwater fish faunal diversity between West Bengal and Odisha, two states of middle-east India. Work is mainly based on the available published literature on the freshwater fish faunal diversity, checklist for fish, monograph of the area under study. Result reveals the existence of 345 species of fish belonging to 50 families under 14 orders. Analysis of data shows a slight similarity of freshwater fish faunal diversity between two states is quite expected because both the states differ in their physiography and ecology. The present report may serve as a helpful document for freshwater aquaculturists as well as fishery researchers for their future planning of research work on the subject of the study area
Record of hill stream catfish Glyptothorax telchitta (Hamilton-Buchanan, 1822) from Paschim Medinipur district, West Bengal, India
No full textGlyptothorax telchitta (Hamilton-Buchanan, 1822) is a benthic hill-stream Sisoroid catfish that inhabits the mountain waters of the Indian Himalayas and in China, Tibet and the Sunda Islands. It is also a common hill stream catfish of the northern region of West Bengal. The present work reveals that the species is available in the Shilabati river basin, Ghatal, Paschim Medinipur, West Bengal. Therefore, Glyptothorax telchitta (Hamilton-Buchanan, 1822) is a widely distributed hill stream species and extends to the lowland area of Paschim Medinipur district of West Bengal, India
MORPHOLOGICAL AND MERISTIC STUDY FOR THE IDENTIFICATION OF Rhinomugil corsula, (HAMILTON -BUCHANON, 1822), RECORDED FROM RUPNARAYAN RIVER, WEST BENGAL, INDIA
No full textRhinomugil is a monospecific genus which is commonly known as mullets with a worldwide distribution in tropical and subtropical marine water bodies. They are not only inhabited in the marine water but also available in brackish water or even in freshwater riverine system. Rupnarayan river is a small range river in West Bengal covered eighty kilometers from Bandar Ghat [22.67°N, 87.77°E], Paschim Midnapore district to Gadiara [22.22°N, 88.04°E] of Howrah district. Naturally this riverine water body is divided into two regions, the upstream with less tidal activity and low saline part and the downstream with high tide and comparatively more saline region. The surveys were conducted from February 2018 to February 2020 during pre monsoon, monsoon and post monsoon period. Specimens were collected by the use of traditional fishing methods operated by the local fishermen. The collected specimens were identified on the basis of existing literature and measurement taken upto one decimal place in the metric system. The present study is a survey work on fish faunal diversity of Rupnarayan River reveals that Rhinomugil corsula is first time reported from the said River and its distribution is being extended up to the upstream part of this river which is less influenced by the tidal flow in freshwater region of the river
