Culture of GET 2002 EXCEL at Two Different Sites

Abstract

This study aimed tofind out tke growth performance of GET 2002 EXCEL at two different sites - Cabittaogan, Sta. Catalina, llocos Sur and Villamar, Caoayan, Ilocos Sur from September I-November 1, 2003. GET 2002 EXCEL cultured in Villamar, Caoayan, R2 got the nighest mean final weight of 128 gm. The lowest was obtained in R1, with 103.5 grams. In Cabittaogan, Sta. Catalina, fishes in R3 had the highest mean final weight of 196.9gm, while those in R4 had the lowest mean final weight of133.93 gm. Result suggests that the freshwater fishpond in Cabittaogan, Sta.
Catalina is better for culturing the GET 2002 EXCEL than the river water in Villamar, Caoayan. This could be attributed to nutrients accumulated in the area and the average surface water temperature. On the monthly average level of the environmental parameters at the culture sites, Cabittaogan had higher salinity readings than Villamar. The pH levels of the waters did not differ much from an average pH of 7.59-8.08 in Villamar, and from 7.27-7.89 in Cabittaogan. GET 2002 EXCEL can be cultured in a freshwater fishpond with a salinity range of 1.66%4.13%, surface water temperature range of 26,99- 28.30, and a pH of 7.27-7.89. Similar studies should be conducted in freshwater fishponds, making use of supplemental feed to reduce the production cost and gain more income. The effect of environmental parameters on the growth of the culture fishes must also be considered, and lastly, results of this study should be disseminated to fish farmers.
