PREPARATION OF THIS DOCUMENT

This document has been prepared within the framework of the Regular Programme activities of the Inland Water Resources and Aquaculture Service of the Fishery Resources and Environment Division. The primary objective of this document is to assist extension workers and other field personnel engaged in fish culture in undrainable ponds to increase production through the application of improved culture technology.

The original manuscript was prepared by Mr. Dilip Kumar of the Central Institute of Fisheries Education, Bombay, India, based on the Indian experience of fish culture in undrainable ponds, and it was edited by Mr. P.C. Choudhury. It is hoped that this manual will be useful to extension workers and fish farmers in areas where fish ponds are not drainable.

Fish culture in undrainable ponds. A manual for extension.
FAO Fisheries Technical Paper No. 325. Rome, FAO, 1992. 239 p.
ABSTRACT
This manual deals with the methods of freshwater fish culture in undrainable ponds as practised in India. The manual is primarily meant for extension workers and aquaculture training institutions. It outlines the basic principles of fish culture and the characteristics of undrainable ponds. The systems of composite carp culture and composite carp culture-livestock farming have been described. Methods of improvement of existing ponds and construction of new ponds have been included. The suitable species for culture, procurement of their seed, stocking ratios of various species under composite culture, etc., have been discussed. Pond management, both pre-stocking and post-stocking, including fish health management and management of common hazards have been dealt with. It also contains information on marketing and economics of fish culture in undrainable ponds.
