FIR /S120 FAO Fisheries Synopsis No 120SAST - Cirrhinus mrigala - 1,40(02)025,03 SYNOPSIS OF BIOLOGICAL DATA ON THE MRIGAL Cirrhims mrig:(Hamilton, 1822) F Q FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS FISHERIES SYNOPSES This series of documents, issued by FAO, CSIRO, INP and NMFS, contains comprehensive reviews of present knowledge on species and stocks of aquatic organisms of present or potential economic interest. The Fishery Resources and Environment Division of FAO is responsible for the overall coordination of the series. The primary purpose of this series is to make existing information readily available to fishery scientists according to a standard pattern, and by so doing also to draw attention to gaps in knowledge. It is hoped that synopses in this series will be useful to other scientists initiating investigations of the species concerned or of related ones, as a means of exchange of knowledge among those already working on the species, and as the basis for comparative study of fisheries resources. They will be brought up to date from time to time as further information becomes available. The documents of this Series are issued under the following titles: Symbol FAO Fisheries Synopsis No. FIR/S CSIRO Fisheries Synopsis No. D FO/S INP Sinopsis sobre la Pesca N° IN P/S NMFS Fisheries Synopsis No. NM FS/S Synopses in these series are compiled according to a standard outline described in Fib/Si Rev. 1(1965). FAO, CSIRO, INP and NMFS are working to secure the cooperation of other organizations and of individual scientists in drafting synopses on species about which they have knowledge, and welcome offers of help in this task. Additions and corrections to synopses already issued will also be most welcome. Comments on individual synopses and requests for information should be addressed to the coordinators and editors of the issuing organizations, and suggestions regarding the expansion or modification of the outline to -FAO: FAO: CSIRO: Fishery Resources and Environment Division CSIRO Division of Fisheries and Oceanography Marine Resources Service Box 21 Food and Agriculture Organization of the United Nations Cronulla, N.S.W. 2230 Via delle Terme di Caracalla Australia 00100 Rome, Italy I N P: NM FS: Instituto Nacional de Pesca Scientific Publications Office Subsecretaría de Pesca National MarineFisheriesService, NOAA Secretaría de Pesca 1107 N.E. 45th Street Secretaría de Industria y Comercio Seattle, Wa. 98105, U.S.A.

Khan Central Inland Fisheries Research Institute (LC.A.R.) Barrackpore, West Bengal India FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS Rome, September 1979 PREPARATION OF THIS SYNOPSIS The present document wasincluded in the FAO Species Synopsis Series in view of the growing importance of Cirrhinus mriqala in fish culture,especially on the Indian subcontinent. The details set out in thispaper are based on data collected by the authors in the course of their personal research work on the species andalso on information compiled from various sources, most of which are included in the reference list.
