| plicatilis rotundiformis línea S y B. plicatilis hepatotomus línea L usándolo como una herramienta para evaluar el ambiente acuático y empleando la fracción soluble en agua (FSA) de tres hidrocarburos: Petroleo Crudo (PC), Diesel 2 (D2) y Diesel 6 (D6). Los valores de CL50 determinados para B. plicatilis rotundiformis a 24 y 48 h de exposición de FSA de PC, D2 y D6 fueron 0.13, 0.04; 0.65, 0.14 y 4.20, 0.33 mg/L, respectivamente. Los valores determinados de CL50 para B. plicatilis hepatotomus a 24 y 48 h de exposición de FSA de PC, D2 y D6 fueron 0.23, 0.05; 1.36, 0.13 y 3.47, 1.01 mg/L, entre los tres hidrocarburos evaluados. El orden de ecotoxicidad disminuyó a 24 y 48 h de exposición para ambas subespecies: petróleo crudo > Diesel 2 > Diesel 6. No... |

| Much progress has been made in the last decades in the industrial farming of several species of marine fish. The pioneering country has been Japan with the red seabream, however, in the last decade Europe made quick progress with seabass and gilthead seabream. Today Japan is still the biggest producer of marine fish fry with about 200 million fry per year, 70% of the production consisting of red seabream and Japanese flounder. Without any doubt, the most significant progress achieved during the last decade has been the result of improved nutrition, more particularly through the manipulation of the fatty acid profile of the live preys <i>Brachionus</i> and <i>Artemia</i> by application of enrichment or boosting techniques with... |

| Studies were carried out to quantify the functional response and prey selectivity of larval (1-5 weeks old) of Moenkhausia sanctaefilomenae, a widely cultured ornamental fish, using four rotifers (Brachionus calyciflorus, B. havanaensis, B. patulus and B. rubens) as prey. Regardless of larval age, B. havanaensis was not selected, while B. rubens and B. calyciflorus were preferred. B. patulus was selected only after three weeks. When fed B. calyciflorus, the larvae showed increased prey consumption with increasing age, but remained as plateau around 80 prey individuals. M. sanctaefilomenae consumed much lower individuals of both B. havanaensis and B. patulus, while B. rubens was consumed in higher numbers starting from the first week (about 35 ind. larva-1... |
