Ongoing research studies on maturation and spawning of milkfish, Chanos chanos at the brackishwater shrimp and milkfish culture applied research and training project, Jepara, Indonesia

The paper gives an account of the research work carried out at Jepara, Indonesia, on induction of maturity of milkfish in ponds and enclosures, and procurement of the spawners from the wild for seed production by hypophysation. Seven to eight years old pond grown milkfish were found sexually immature. Experiments are being conducted for growing and inducing maturity in 1-2 years old milkfish in fertilized ponds with regular tidal flow of water and also under regular hypophysation program. Milkfish spawners collected from sea had a few males in oozing condition and females mostly spent

Fish culture in India

Fish culture is very popular in the States of Bihar, Bengal and Orissa. In other states, too, there has been a marked awakening of interest in inland pisciculture

On a new species of Praegeria occurring in the Sandy beach, Madras

From the foregoing pages it is clear that the present form shows a number of interesting features in which it markedly differs from the other species of the genus. These characters seem to me of sufficient value for the creation of a new species for its reception and for which I propose the name Praegeria gopalai. The important characters of this species can now be summarised as follows: Minute slender worm, 4 to 10 mm. long, with 25 to 50 setigerous segments; ventral cirrus of the buccal parapodium globular; ventral cirrus of the first setigerous foot slightly elongated; anal segment with two conspicuous groups of caudal glands; only a single pair of sperm-sacs, genital funnels and copulatory organs in the male; secondarily median testis enclosed in a membrane and often extending into two segments; tapering entire copulatory organ provided with a large spinous papilla sperm-sacs having double saccular expansions; in the female, one or two ovarian groups covered over by a membrane and each group extending into 6 to 15 consecutive segments; receptacula seminis and genital funnels corresponding to the number of ovarian groups; parapodia of the segment carrying the receptacula seminis completely atrophied and carrying only two acicula; sperms from the receptacula seminis nail shaped having developed a conspicuous terminal hood. Locality: -Sandy Beach, Madras. Holotype: -In the Indian Museum, Calcutta

On the mortality of carp fry in nursery ponds and the role of plankton in their survival and growth

As in China, collection of millions of early fry of major carps from rivers and stocking them in nurseries for rearing is a common |practice in India, particularly in Bengal, Bihar and Orissa. Different types of ponds, small or large, seasonal or perennial, shallow or deep, are used as nurseries; and different methods of preparation of the ponds are followed. There is, however, very little reliable information about these practices, most of which are known only to a few farmers who keep the information as family secrets handed down from generation to generation. On such important aspects like the density of stocking and percentage of survival, also, our information is meagre. Even the expert fish farmer is unable to ensure that his nursery pond will yield a satisfactory return every year

A bibliography of parasites and diseases of marine and freshwater fishes of India

With the increasing demand for fish as human food, aquaculture both in freshwater and salt water is rapidly developing over the world. In the developing countries, fishes are being raised as food. In many countries fish farming is a very important economic activity. The most recent branch, mariculture, has shown advances in raising fishes in brackish, estuarine and bay waters, in which marine, anadromous and catadromous fishes have successfully been grown and maintained
