Efecto de la frecuencia de alimentacion en alevines de denton Dentex dentex Linnaeus, 1758 durante la fase de preengorde


, : Efecto de la frecuencia de alimentacion en alevines de denton Dentex dentex Linnaeus, 1758 durante la fase de preengorde. Boletin Instituto Espanol de Oceanografia 18(1-4): 115-117

The present paper examines the impact of three different feeding frequencies on fingerlings of the common dentex Dentex dentex Linnaeus, 1758, in terms of their survival, agonistic behaviour and growth. Three trials were carried out, each with replicates, and their results showed that feeding frequency influences fish growth, with significant differences in length and weight between manual and automatic feeding. No significant differences in survival rate or agonistic behaviour were found in the three trials. The best growth results were obtained with continuous automatic feeding (24 h, every 4 minutes), and continuous artificial lighting with fluorescent lamps (intensity of 1 000 lux).
