Observations on the fishing potentiality of the shelf and slope waters along the s. w. coast of India based on the fishing results of IFP vessels

Availability of resources is perhaps the most important factor which determines the success of any Industry. In the case of fishing industry. the availability of fishable concentration of fishes and other marine life assumes great significance since the success of the fishing operation is entirely dependant on the availability of resources which can be effectively exploited with the fishing equipment carried on board

Indian seas: a megadiversity hotspot

Marine biological research in India dates back to the 18th century, and the surveys and expeditions conducted by Europeans, particularly the British. The most notable among these pioneers were great naturalists such as Francis Day (1829-1889) , Nelson Annandale (1876-1924) and Herbert Robinson (1874-1929) who worked during the latter part o f the 19th century and early 20th century. This foundation helped India to create a network o f marine research laboratories in government funded institutions and universities all along the coastline

Reductive alkylation of aromatic amines over copper chromite: Deactivation of catalyst

1115-1117Reaction of aniline with acetone in the presence of hydrogen and copper chromite as catalyst at 140°C and 50 kg/cm2 pressure has been studied with a view to understand the reasons for the rapid deactivation of the catalyst. Poisoning of the surface by the by-products of the reaction is the major cause of deactivation

Description of the male of Caligus hilase Shaw (Copepoda, Caligidae)

Caligus hil.rae Shen, 1957, is unique in the possession of a comparatively very long four-segmented abdomen, long anal laminae which are nearly three times as long as broad and in the absence of the sternal fork

Seed production and hatchery management of Penaeus indicus

CMFRI has developed an economically viable and ecofriendly hatchery technology suited to Indian conditions, for the seed production of Penaeus indicus. The technology consists of a number of package of practices such as broodstock management, spawning, larval rearing, diatom culture and preparation of particulate feed for the postlarvae. The various package of practices are compartmentalised in separate units so as to maintain proper hygiene and prevent/reduce the incidence of outbreak of diseases. The larvae from protozoea through mysis 2/3 are fed exclusively on diatom. From mysis 2/3 stage to postlarvae 2 to 5 are fed with prawn custard along with diatom. The postlarvae 2 to 5 are transferred to the nursery and reared using egg prawn custard. Details on the maintenance of live feed culture and preparation of egg prawn custard are given. Mention is also made on the hatchery management and economics of two types of hatcheries. The main emphasis of the technology is to make the best use of the available resources and to harness the natural solar radiation and light to the maximum thereby providing an ecofriendly technology which is cost effective
