Descripción
In order to provide seed fish for emerging Clarias culture, the Thai Department of Fisheries implemented a public program for collecting fry from the wild. Methods for collecting the fry were demonstrated by government fisheries officers. Collected fry were purchased by the Bangkhen Fisheries Station. Some were re-distributed to fish farmers while some were first reared to a 3 to 5 cm size before being passed on. About 180,000 and 3,000,000 fry were produced by this program in 1959 and 1960, res pectively. 1 This working paper is a translated version of a report which appears in the Thai Fisheries Gazette, 14(2):105–111(1961). A first draft in English was prepared by Tawan Chookajorn, fisheries biologist, National Inland Fisheries Institute, Bangkhen, Bangkok. The version presented here was developed by Dr. Alex Fedoruk, Senior Fisheries Biologist with DoF-UNDP/FAO project THA/75/012 in Thailand, from the draft and discussion with Thai fisheries workers. Transferring information by th is means is subject to the limitations inherent in relaying from one language to another. Shortfalls in the information presented may thus be a reflection of communication rather than of source. 2 Formerly, fisheries biologist, Bangkhen Fisheries Station, Bangkok, Thailand. Presently, Provicial Fisheries Officer, Singburi Province, Thailand.
