Background: Fishes of the family triacanthidae are highly diversified throughout the world, but studies on these fishes were very limited in India. Now a day’s catch of species belongs to this family increasing and showing new geographical distributions due to overfishing of top predators. Methods: Experimental fishing method was conducted by using the M.F.V Narmada-IV vessel of ICAR- Central Institute of Fisheries Education, Mumbai. The vessel operated with a demersal trawl net with a cod-end mesh size of 30 mm. Spatial distribution map of the family Triacanthidae was generated from previous literature using the IDW interpolation method in Arc GIS 10.4.Result: New distributional record of silver tripodfish, Triacanthus nieuhofii Bleeker, 1852 was recorded for the first time from the Mumbai waters, northwest coast of India. Spatial map showing that the species of the family Triacanthidae were highly diversified along the east coast than the west coast of India.

A total of 16 species of the family Leiognathidae have been collected from the commercial landings from Cochin and Neendakara on the western coast of India from 1998–2000. Detailed morphometric data have been collected and all 16 species are redescribed with live color photographs here. Various relationships in the morphometric characteristics have been studied and regression equations fitted to enable comparison of the populations of these species from Kerala with those from other regions. Of the 16 species collected and described in the present work, five species, Nuchequula nuchalis, Equulites absconditus, Equulites leuciscus, Aurigequula longispina, and Gazza achlamys, are reported for the first time from the entire western coast of India.

The benthic ctenophore Vallicula multiformis Rankin, 1956 is recorded for the first time in the Arabian Sea, from the Gulf of Kutch, west coast of India in March 2013. This occurrence represents a remarkable extension of its geographic distribution that until now included only known the Pacific and Atlantic oceans.

The present paper documents the molecular diagnosis and genotyping of white spot syndrome virus (WSSV) isolates collected from different shrimp farms of Gujarat, north-west coast of India. Preliminary diagnosis was done using singletube PCR and genotyping of isolates by analysis of variable number tandem repeat sequence (VNTRS) in minisatellites viz., ORF 94, ORF 125, ORF 75 and ORF 75 flank. Out of the 79 samples analysed, 32 (33.80%) were positive with low (54.17%), medium (8.33%) and high (37.50%) severity of infection. Genotyping, using ORF 94 revealed that repeat units (RUs) 4 and 11 were the most frequent ones (32%) while ORF 125 showed 5 different repeat types of which RU 5 was the most common (45.83%). Two genotypes were observed for ORF 75, one showed multiple repeats of two 45 bp, followed by a 57 bp, whereas the other showed two repeats that included 5 and 4 repeats of 45 bp. Sequence analysis of the 54 bp variable sequence of ORF 94 RU type 4 revealed single-nucleotide polymorphism (SNP) at 47th base. Based on the results from ORF94, dominance of RU types 11or 4 were recorded for the first time in India and one sample showed 2 bands of different sizes indicating the prevalence of two different genotypes infecting the same pond at a given time. Further, no correlation could be observed between the virus genotype and the severity of the mortality in the outbreaks. The results suggest the widespread occurrence of WSSV in the region and circulation of distinct virus genotypes.

Geographical Distribution Pattern

The geographical distribution of the family Limacinidae in the Northeastern coast of Brazil was analyzed by taking into account the most relevant ecological aspects, aiming to increase the knowledge about the Family. The material was collected during the 4th Oceanographic Expedition of the REVIZEE program (Assessment of the Sustainable Potential of Living Resources in the Exclusive Economic Zone - Avaliação do Potencial Sustentável de Recursos Vivos da Zona Econômica Exclusiva), in the months from September to December 2000. The studied area is located between 00°46’45”N and 13°53’45”S and between 29°15’40”W and 39°49’42”W, where six trips were performed, totaling 123 stations. The samples were collected using a bongo net (300- and 500-µm mesh size and net mouths of 60 cm in diameter) coupled with a digital flowmeter in oblique hauls from a depth of 0 to 200 m. For this study, the organisms retained in the 300-µm mesh were considered. On board the ship, the samples were placed in plastic containers, labeled, and fixed in 4% formaldehyde buffered with sodium tetraborate. In the laboratory, the samples were analyzed on a “Bogorov” tray under a binocular stereomicroscope. A total of 5655 individuals of the family Limacinidae were examined and were distributed as follows: 3 genera and 5 species. Representatives of the family Limacinidae were observed at high temperatures and salinities and were thus characterized as tropical and euhaline.Heliconoides inflatus was the species with the greatest abundance and frequency. Limacina lesueurii proved to be a rare, infrequently observed species. Limacina trochiformis andL. bulimoides were not abundant or frequent.Limacina lesueurii and L. bulimoides were recorded in neritic waters for the first time; this was also the first record ofL. lesueurii in the waters of Northeastern Brazil.Limacina trochiformis and L. bulimoidesexhibited wide distributions, although they were neither very frequently observed nor abundant. The distribution of Thielea helicoideswas restricted to oceanic waters. A correlation between Limacina bulimoides, Heliconoides inflatus, Thielea helicoides, and L. lesueurii was observed because they coexisted in the same niche.

Longtail Tuna

Longtail tuna (Thunnus tonggol, Bleeker, 1851), the largest growing species among neritic tunas have a unique distribution pattern globally. Northern Arabian Sea together with the Oman Sea and Persian Gulf in the north-western Indian Ocean is considered to be the major area where the species is abundant and form sizeable fisheries globally. India has an artisanal tuna fishery and contributes nearly 10% of the longtail tuna landing in the region, with Gujarat alone contributing nearly 80%. The paper updates on the longtail tuna fisheries in the region with focus on the north-west coast of India together with its spatial characteristics. Clues on the areas of abundance of the species along Gujarat coast over the seasons and temporal movements of different ontogenetic stages in the shelf areas are revealed. The study sets prelude to a cost effective and participatory collection of spatially referred data on the artisanal and small scale fisheries in the region.

Turris clausifossata, a Conoid, Turrid is being reported for the first time from Gopnath coast, Gulf of Khambhat the state of Gujarat situated on the west coast of India. Turris clausifossata was first recorded7 from Dwarka, Gulf of Kachchh, Gujarat (21°49’N, 68°55’E), but not brought to light as first record to the west coast of India. Yet, its occurrence was reported only at two coasts of Gujarat. Current research reveals that Turris clausifossata is extending its distribution range to the south of Dwarka on the west coast of India. Present study was carried out from April 2015 to March 2016 and in this study, a status of species presented in form of population dynamics and seasonal availability.
