PREPARATION OF THIS DOCUMENT

This document has been prepared within the framework of the Regular Programme activities of the FAO Inland Water Resources and Aquaculture Service of the Fishery Resources and Environment Division. Its primary objective is to provide assistance to extension personnel and to other field personnel engaged in fish culture activities eventually making it possible to substantially increase fish production through their cultivation.

This manual deals with artificial and semi-artificial propagation and rearing of fry of warm-water finfishes cultivated in freshwaters. All those techniques developed in the laboratory, but yet to be proved in the field on a commercial scale, have been excluded. Similarly, fish species of local importance only and those whose propagation techniques are similar to those of the species dealt with here have also been excluded. Both the earlier non-sophisticated methods as well as modern techniques have been described, since the necessary facilities required for applying modern technology may not be available to all readers.

The original manuscript was prepared by Dr. E. Woynarovich and by Dr. L. Horváth, in Hungary. The text was revised by Prof. H.P.C. Shetty in India and finally edited in Rome by Mr P.C. Choudhury. The original figures were reviewed by Dr A.G. Coche and by Mr C. Nugent in FAO, Rome, before being finally edited by P.C. Choudhury also.

ABSTRACT

This Manual deals with the artificial propagation of warmwater finfishes. Being primarily meant for the extension workers and aquaculture training institutions, it is profusely illustrated. It outlines the basic biological aspects of reproduction in fish and presents the various techniques being used for the collection of fertilized eggs, the artificial fertilization of eggs and the subsequent rearing of larvae and fry. Hatchery and nursery facilities, including equipment and tools, required to set-up a medium-size fish seed production and distribution centre are also included. The various methods of transporting fish eggs, larvae, fry and fingerlings are discussed. The methods of collection and preservation of fish pituitary glands and the dosage of pituitary extracts used for inducing successful spawning in various warmwater fishes are dealt with. Finally, artificial propagation techniques for some commercially important warmwater fishes are presented.
