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
