The trophodynamics of Nemipterus japonicus (Bloch, 1791) along the north-east coast of India was studied during 2012-2015 based on specimens collected from trawl landings at Digha, Paradeep (northern region), Visakhapatnam and Kakinada (southern region). Crustaceans were the preferred prey with index of relative importance (IRI) of 50% in the northern region and 42.4% in the southern region. Among crustaceans, Oratosquilla dominated in both the regions followed by crabs and several species of penaeids and nonpenaeids. Finfishes ranked next in importance (IRI% of 32.1 in northern region and 39.9 in southern region) and included Stolephorus spp., silverbellies, Coilia sp., other clupeids, Apogon spp., mackerel, sardines, eels, priacanthids, Bregmaceros sp. and sciaenids. Along northern region, in juveniles and preadults, the diet comprised chiefly of crustaceans (IRI% of 72.27 and 52.76), followed by finfishes (IRI% of 15.37 and 27.65). In the southern region, adult fishes exhibited higher preference for finfishes (IRI% of 47.5 to 62.8). Feeding intensity was low throughout the year with close to half (48.23% in northern region and 43.67% in southern region) of the fishes exhibiting empty or trace stomach conditions which increased with an increase in age and size of fish. High similarity of 75.54% in the northern and 84.19% in the southern region was recorded in the diet contents of smaller and moderate sized adults. Annual and seasonal mean similarity in the diet components between the regions was 69.9 and 53%. Prey contents in juveniles between both the regions exhibited a similarity of 59.5%, while preadults and adults recorded similarities of 62.7 and 68.2% respectively.

AbstractCrenidens macracanthus was originally described in 1874 based on a single specimen collected from Chennai (Madras), south-east coast of India. In 1875, the species was synonymized with C. indicus without citing any valid reason. Since then, no taxonomic studies have been attempted for the genus Crenidens, except in 2013 the species was resurrected from synonymy and redescribed as a valid species based on the holotype and non-type specimen. In view of the fact that C. macracanthus is a poorly known species, it is redescribed based on examination of 30 additional specimens of 105.8–162.2 mm SL, collected from Puri, Odisha, north-east coast of India (Bay of Bengal) from 2017–2019, using morphological and molecular examinations. Our study provides a detailed morphological description, first colour photographs and phylogenetic analysis using COI barcodes of the species. The study has expanded the range in several morpho-meristic characters in comparison with the type and non-type specimens described earlier. The species in fresh condition can be easily distinguished from its two congeners (C. crenidens and C. indicus) by the yellowish tip of the lower caudal-fin lobe. Our study has also extended the distribution range of C. indicus (previously known only from the north-eastern Arabian Sea) to the eastern Indian Ocean, based on examination of a preserved specimen collected from Tuticorin, Tamil Nadu.

Cymbastela sodwaniensis sp. nov. (order Halichondrida: family Axinellidae) is described from the subtropical waters of Sodwana Bay on the north-east coast of South Africa. The genus was previously unknown from southern Africa or the western and eastern parts of the Indian Ocean. This record represents the westernmost extent of this predominantly Indo-Pacific to Australasian genus. This new species record brings the number of Cymbastela species described to a total of nine.

The reproductive biology of Nemipterus japonicus (Bloch, 1791) along the north-east coast of India was studied during 2012-2015 based on samples from the trawl landings at Digha, Paradeep, Visakhapatnam and Kakinada. Adults dominated the landings. Significant contribution by females was observed in most months of the year. Size at first maturity for females was 15.1 cm. Peak spawning season was during August to February and September to March in the northern and southern regions. Maturity and gonado-somatic index (GSI) were found to correlate well with sea surface temperature (SST). Fecundity increased with length and weight and varied from 13,176 to 1,30,798. Ova diameter distribution indicated the species to be a multiple/batch spawner.

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.
