Map. Cornejo et al., Effect of the macroalga Caulerpa sertularioides on the development of Penaeus californiensis shrimp (Decapoda : Peneidae), REV BIOL TR, 47(3), 1999, pp. 437-442
The effect of the macroalga Caulerpa sertularioides on the growth, survival
and yield of captive yellowleg shrimp Penaeus californiensis (Holmes, 1900
) at winter temperatures (14 to 21 degrees C) was studied at La Pat, B.C.S.
, Mexico. Nine experimental units (three per treatment) consisting in 150 I
-fiberglass tanks were used. Shrimp growth with macroalgal presence was 3.9
8 +/- 0.4 g after 10 weeks, survival was 100% and yield 36.24 +/- 4.3 g. Th
ese results were better than those obtained with indirect presence, and abs
ence of the macroalga, which were not different among themselves. Under ind
irect macroalgal presence growth, survival and yield were 0.73 +/- 0.4 g, 7
5+/- 10% and 7.8 +/- 1.2 g. Without macroalgae, corresponding values were 0
.46 +/- 0.4 g, 68.7 +/- 12% and 5.6 +/-1.1 g. Significant differences were
found between "absence" and "indirect presence". The macroalgae possitively
affect the development of this shrimp in captivity.
