PORCHAS CORNEJO, Marco Antonio et al. Efecto de la macroalga Caulerpa sertularioides en el desarrollo del camarón Penaeus californiensis (Decapoda: Peneidae). Rev. biol. trop [online]. 1999, vol.47, n.3, pp.437-442. ISSN 0034-7744.

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) consisting in 150 l-fiberglass tanks were used. Shrimp growth with macroalgal presence was 3.98 ± 0.4 g after 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 macroalgal 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. Significant differences were found between "absence" and "indirect presence". The macroalgae possitively affect the development of this shrimp in captivity.
