Abstract | An acceptable and practical procedure was sought to minimize genetic damage during broodstock selection and management. Nile tilapia (Oreochromis niloticus ) and common carp (Cyprinus carpio ) were studied from one fish farm in Udorn Thani Province, and three fish farms and one Department of Fisheries Station in Khon Kaen Province. Selection intensity of the growth rates was estimated for these farms . Scale margin techniques were applied to study the growth rates. Calibration equations were formulated for estimating the growth rates in fish of different size and sex and were used to compare the growth rates of fish from these farms. Fish management of each farm was also recorded. Fish growth rates from Udorn Pattana Farm in Udorn Thani Province were the best and corresponded with good management. In Khon Kaen Province the growth rates of fish from Khon Kaen Farm were better than these of other farms. Almost all of the fish farm studied had a positive direction of selection. The gene flow in the studied areas was an open system but also close system within farm. |
