Resumo: |
The Método de Alimentação Comercial (MAC) and the Método de Alimentação Artemia (MAA) were evaluated, aiming to maximize the growth and survival rate of the Litopenaeus vannamei post-larvae, reducing the feeding cost/benefity, in the post-larvae culture in nursery tanks. The experiment took place at the Tabatinga Aquacultura Ltda farm, in february 2003, using nursery tanks of 60m3, where the post-larvae (Pl19) were stocked at 16Pl’s/L. The end of ten days of culture, the weith-length relationship and time, that MAA fed post-larvae had heavier a significant growth (in weigth) (P<0,05) than those treated with MAC. The models could had been written in the following form: W(g) = (0,0069MAC + 0,0094MAA).L(cm)2,9094 (R2= 99,33%); W(g)=e0,1739T(dias)-5,4083MAC-5,1609MAA (R2=99,71%). The post-larvae survival treated with MAA(86,25%), was higher than (P≤0,05) other method (62,12%). The physical, chemical and biological parameters of water of the tank, where the MAA was administrated, were always smaller than MAC and consequently induced a lower daily increase rate. We could conclude that the growth and survival rates of the post-larvae of L. vannamei results were better when Artemia franciscana nauplii were used in nursery tanks. They represented a significant reduction (P<0,01) polluting levels. Economicaly, the artemia was viable in when compared to artificial food. |
