碩士 / 國立臺灣海洋大學 / 水產養殖學系 / 105 / This study used a behavioral response method to test attractiveness of different ingredients, and investigate the effects of concentration, time and mixtures of several selected attractants on the attractiveness for pacific white shrimp, Litopenaeus vanname.
Experiment 1: 30 different attractants was divided into 6 groups randomly and each group had five replications by comparing behavioral response in 20 minutes with double-elimination tournament to test attractiveness. Among 3% tested ingredients in starch, attractant F (F) had the best performance, with squid meal (Q), poultry meal (P), scallop meal(C) and krill meal (K) were top 5. Seaweed B was the worst attractant. Among 1% tested ingredient in starch, attractant X(X) had the best performance, with isoleucine, taurine, aspartic acid and glycine were top 5.
Experiment 2-1: the concentration effect of 0%, 3%, 6%, 9% of the top five in 3% ingredients in Experiment 1 were tested. Attractiveness of squid meal did not increase over 3% concentration. Attractiveness of the others increases with the increase of concentration. Experiment 2-2: behavioral response time was extended to 2 hours for the top five in 3% ingredients test in experiment 1. Rank of the top five in this study was similar to that of experiment 1, but all responses were not significant different from each other. Experiment 2-3 was conducted to test different mixed attractants with a combination of two or three randomly of attractant F (F), squid meal(Q), poultry meal (P), scallop meal (C)and krill meal (K), and the results of attractiveness was not significantly different among mixed two or three attractants. However, the mixtures of two attractants with attractant X significantly increased attractiveness.
In experiment 3, A feeding level study was conducted to test seven different supplementations of attractants in a formulated control diet according to the result of experiment 1 and 2 including, attractant F, squid meal, poultry meal, scallop meal, krill meal, FP, FPX. The result of feeding level showed different results as compared with those of experiment 1 and 2 which need further study to find the reason.
