Abstract The present study report the parasitic isopod infection on commercial fishes of the northern part of the east coast of India collected during the period 2010-2015 from the marine water of Odisha and West Bengal. During the study, 394 isopods were collected after examining 2668 fishes. These include 14 species of isopods, out of which 13 belong to 5 genera under the family Cymothoidae, and a single species Alitropus typus belongs to the family: Aegidae. Of theses, 03 species viz., Catoessa boscii, Cymothoa eremita and Nerocila loveni are first record to the northern part of east coast of India. Out of the 2668 fishes examined, 326 examples belonging to 34 species under 19 different families were infected by different isopods. Member of the host fish family Carangidae was more parasitized by isopods, followed by Clupeidae, Scoberidae, and Leiognathidae. The dominant isopods were Nerocila phaiopleura and Catoessa boschii. The total prevalence was 12.21. The prevalence was high on the host fish Alepes djedaba and lowest on Lutjanus johnii. The total infection caused by genus Alitropus was 1.52%, Anilocra was 5.07%, Catoessa was 24.87%, Cymothoa was 0.25%, Nerocila was 65.73%, and Norileca was 2.55%. The isopod prevention was high during the post-monsoon and low during the monsoon period.

The Family

The fish family Cynodontidae belongs to the superfamily Curimatoidea, together with the Hemiodontidae, Serrasalmidae, Parodontidae, Prochilodontidae, Chilodontidae, Curimatidae, and Anostomidae. The majority of the species of this superfamily that have been analyzed to date have a diploid chromosome number of 2n = 54. Differentiated sex chromosomes (with female heterogamety) have been observed only in the Prochilodontidae, Parodontidae, and Anostomidae. The present study provides the first description of differentiated sex chromosomes in the cynodontid species Cynodon gibbus, which has a ZZ/ZW system, and shows that repetitive DNA has played a fundamental role in the differentiation of these sex chromosomes.

First Occurrence

A single specimen of the African spadefish,Tripterodon orbis, was landed in a gill net operating off Visakhapatnam on 13 December 2013. The morphometric and meristic characters of the recorded specimen are described and discussed herein. This is the first occurrence of the species from the north-east coast of India, exhibiting an extension in distribution from the southern to the northern region, along the Bay of Bengal.

Abstract. This paper reports what we believe to be the first record of allogromiid foraminifers from coastal Indian waters. Two species from the Vellar Estuary on the east coast of India south of Madras are described and placed in a new genus Vellaria. The foraminifers live at or near the sediment-water interface and are characterised by the development of a flared, conical or trumpet-shaped apertural structure which apparently serves to attach the test to small sand grains. Allogromiids are delicate and inconspicuous organisms which may be more widespread in esturine and brackish water settings than is currently realised.

Cryptopodia angulata is reported for the first time from Saurashtra coast of Gujarat state. One adult female was found in trawl catch near Sutrapada village of Saurashtra coast on January, 2012. Although the species is not common in Indian waters, this species has been reported from the south east coast of India. This is the first report from Saurashtra coast.

Abstract Two distinct morphologies of Cymothoidae isopod, Lobothorax typus were collected from the marine water of Bay of Bengal, Goapalpur-on-Sea as the first record of this parasite from coastal water of Odisha, India. All specimens were found attached to the buccal region of different individuals of the same host fish Trichiurus lepturus. With the aid of COI gene sequencing and morphological analysis, the individuals were found to be conspecific. The most prominent variation among the two morphologies includes the size of 5th pereonite and pleon length to total body length ratio. These variations are as a result of the biphasic moulting process. Maximum Likelihood (ML) tree analysis based on COI gene sequences concluded the monophyletic taxonomy of different buccal attaching genera under the family Cymothoidae which is in congruence with their morphological divergence.

Commercially Important

In India, the two spotted razor fish is not among the main commercially important fisheries but has food and ornamental value. We report the occurrence of Iniistius bimaculatus (Rüppell, 1829) in Digha based on a 199mm long specimen. This species was previously reported in India only from the south-eastern and western coasts. Morphometric and meristic measurements were taken and the specimen was deposited in ICAR-Central Institute of Fisheries Education, Kolkata Centre Museum.
