Studies on planktonic amphipods of the Indian Seas

An account of the past 50 years of research carried out on Amphipoda by the Central Marine Fisheries Research Institute and most relevant works carried out on the topic from the Indian seas are presented. The paper highlights the qualitative and quantitative composition, distribution in space and time and the taxonomy of planktonic :imphipods of neritic and oceanic waters of Indian region as well as from Antarctic waters. Considering the gap in the work done, future research progranvnes are suggested with a view to satisfy the present need

Studies on Ostracods of the Indian Seas

An account of the past five decades of research carried out on ostracods by the staff of the Central Marine Fisheries Research Institute and most relevant works carried out by others on the topic from the Indian seas are presented. This is a review of the major work done especially the distribution and abundance in space and time along with, descriptions of species in the inshore as well as in the oceanic regions of the Indian sea

Distribution of Brachionus species (Phylum Rotifera) in Cochin backwaters, Kerala, India

Distribution of thirteen species of Brachionus in nine stations from Cochin backwaters was studied during August 2000-July 2002. Of the 13 species, B. plicatilis and B. rotundiformis were observed in all the stations. B. rotundiformis was dominant with 85.76%. Detailed observations on the qualitative and quantitative distribution are presented

Rhinopias eschmeyeri Condé, 1977 (Family Scorpaenidae) - a new record from Indian waters

The Eschmeyer's scorpionfish, Rhinopias eschmeyeri is reported for the first time from the Indian waters. Two specimens of this species were collected from trawlers operated in Gulf of Mannar, southeast coast of India, during November, 2009. Comparison of morphometric and other characters with the holotype and other reported specimens confirm the identification

The rotifer Brachionus rotundiformis Tschungunoff isolated from Cochin backwater, Kerala.

The rotifer, Brachionus rotundformis along with a smaller strain were isolated for the first time from Cochin backwater. The newly isolated B, rotundformis has a length range of 98-210 microns showing a modal size of 168 microns, while in the smaller strain the length ranged from 70-168 microns with modal size at 140 microns. The lorica width to length ratio for B. rotundiformis is 0.7 and that for smaller strain 0.8. The smaller strains are of much use for feeding fish larvae especially those having small mouth size

Ecology of rotifers in Cochin backwaters, Kerala, India

Water and rotifer samples were analysed simultaneously from nine different habitats along Cochin backwaters during the period from August 2000 to July 2002. The correlation coefficients were worked out between rotifers and thirteen environmental characteristics with respect to each station separately as well as in the study area as a whole. Rotifers showed significant positive correlations with nitrite, chlorophyll a, total suspended solids, phosphate and biochemical oxygen demand, in the study area. Station-wise results on correlation along with the levels of significance are presented and discussed

New records of two finfish species from Indian waters

Two species of fishes, namely Ablabys binotatus (Family Tetrarogidae) and Rhinopias eschmeyeri (Family Scorpaenidae) were recorded in trawl (Roller madi) landings from the Gulf of Mannar, south-east of India, which are the first reports from India
