| Abstract |
Ecological surveys using small otter trawls provide useful and informative data on demersal fish and epibenthic macroinvertebrates of coastal soft bottom areas. This report presents recommendations for selecting and using small otter trawls in coastal biological surveys and suggests methods for handling catches and processing data. Use of small trawls in monitoring surveys is an adaptive use of their original purpose in commercial fishing. Many investigators have made effective use of small trawls in ecological surveys and some of this work is reviewed. Nets ranging in headrope length from 10 to 16 feet are recommended for shallow waters, estuaries, lagoons and aboard small boats; 25-foot nets are recommended for open coastal areas. Use of the gear, accessory gear and care and trouble-shooting procedures are described. |
