Efecto de la macro alga <i>Caulerpa sertularioides</i> en el desarrollo del camarón <i>Penaeus califoniensis</i> (Decapoda: Peneidae)

Abstract

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°C) was studied at La Paz, B.C.S., México. Nine experimental units (three per treatment) c()nsisting in 150 l-fiberglass tanks were used; Shrimp growth with macroalgal presence was 3.98 ± 0.4 gafter 10 weeks, survival was 100% and yield 36.24 ± 4.3 g. These results were better than those obtained with indirect presence, and absence of the macroalga, which were not different among themselves. Under indirect rnacroalgal presence growth. survival and yield were 0.73 ± 0.4 g, 75± 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. Significaílt differences were found between "absence" a1id "indirect presence".The macroalgae possitively affect the development of tpis shrimp in captivity
