【 摘 要 】

Substitutingplant protein for fish meals is an alternate protein source in the diet ofreared fish. By replacing fish meal with Soybean Meal (SM) or Cassava Meal(CM), this study determined the effects of diets influenced by local wisdomcontaining plant protein meal, SM, CM, or a commercial formula (FMTM)on the survival and growth rates of snakehead fish (Channa striata) withnutritional and economic analysis. After acclimatization, snakehead fingerlings(10 fish/tank) were randomly allocated inthe nine cement tanks. Three tanks each for Soybean Meal (SM) diet; CassavaMeal (CM) diet; and commercial diet (FMTM). Fish weights weredetermined every four weeks for the 12 weeks. At the end of each experiment,the Survival Rate (SR), growth performance values, and cost reduction werecalculated. After 12 weeks, there were no significant differences in SR amongtreatment groups. The growth performance of fish in SM dietary treatment and FMTMdietary treatments had no significant difference. Although, the specific growthrate of fish fed CM diet was slightly less than SM and FMTM diet. The soybean meal or cassava was substituted for a fishmeal resulting in 11.6 and 7.9% economicvalue (cost/100g fish product), respectively compared to the commercial diet. However,the CM diet resulted in the lowest Feed Conversion Rate (FCR) in thisexperiment. There were no significant differences between FCR and ProteinEfficiency Rate (PER). The results revealed the beneficial effect of dietsinfluenced by local wisdom, especially the addition of soybean, in terms ofweight gain promotion and feed cost reduction. These findings can be applied todevelop low-cost diets for snakehead fish, supporting the flexibility andcompetitiveness of the snakehead fish farming industry and reducing the numberof small fish used for fishmeal.
