Fish sauce from two species of unexploited deep sea fish Peristedion adeni and Peristedion weberi

Two species of unexploited deep sea fish Peristedion adeni and Peristedion weberi caught from the Exclusive Economic Zone of India were subjected to fermentation at ambient temperature (30 ± 2°C) in the presence of salt in 4:1 ratio. Periodical analysis of the fermented product was carried out up to one year. The sauces had brownish yellow colour and conformed to special grade of the standards prescribed by the Food and Drug Administration. Further solubilization of protein after 9 month's maturation was not appreciable.

Inactivation of Vibrio parahaemolyticus in drinking water

A study was conducted in the Cochin area of India to determine the effect of drinking water on Vibrio parahaemolyticus, a bacterium that contaminates fish harvested from marine and estuarine environments. Times of fresh-water exposure required to inactivate these bacteria are given. Findings indicate that the washing of fish and equipment used to handle the fish in drinking water may decrease in the number of viable Vibrio cells and thus aid in prevention of food poisoning.

Quality of cured fish on the west coast: comparative study with the IS specifications

Moisture and salt content in cured fish products from various centres on the west coast of India are compared. The moisture contents varied in samples from different centres, whereas the salt content remained more or less uniform. The deviations from the Indian standard specification were highly significant in both cases. The high mean moisture values and low salt values with respect to accepted standards are indicative of the improper drying and poor salting.

A method of immersion of panels for ecological studies on marine fouling and boring organisms

The importance of studies on the biology of marine foulers and borers needs no emphasis since they cause damage to submerged wooden structures resulting in considerable economic loss. In order to study their occurrence, settlement and to assess the rate of destruction to timber, several immersion techniques using iron racks, cages and rafts have been adopted. On the east and west coasts of India, at the Marine Centres of Forest Research Institute (Waltair, Madras, Cohin and Bombay) investigations have so far been carried out employing the first two methods.

Development of cell culture from caudal fin and heart of Tor tor (Hamilton-Buchanan)

Tor mahseer (Tor tor), possess high commercial and recreational value as they are potential game as well as food fish of India. Two cell culture systems were developed from fin and heart of T. tor (Hamilton-Buchanan). The explants excised aseptically from fingerling of T. tor were cultured in Leibovitz-15 (L-15) medium with 20% fetal bovine serum (FBS). Radiation of cells started after 72 hours and 48 hours of explant attachment from caudal fin and heart respectively. Confluent monolayer of cells with heterogeneous morphology around fin explants was observed after 7-10 days, where as a homogenous confluent layer of fibroblastic cells from heart explant was observed after 12-13 days. The establishment of cell culture systems from different organs and tissues of commercial important species would facilitates in vitro research.

Ecosystem characterisation of Indian coast with special focus on the west coast

CSIR-National Institute of Oceanography (CSIR-NIO), Goa, India in collaboration with CSIRO, Australia organised a 2 day national experts workshop to: pool information between fisheries and oceanography experts; verify a draft ecosystem characterisation for the east coast of India; and develop a draft ecosystem characterisation for the west coast of India.
