Manual de producción de larvas y juveniles de lenguado negro Paralichthys orbignyanus
With the aim of obtaining healthy juveniles capable of accepting inert food to be fattened up to commercial size, the larval culture of marine fishes is based on the rigorous control of culture conditions (light, temperature, feeding, water quality, etc.). The rapid larval development of marine species makes that larval culture, considered the most critical stage of the whole period, be relatively short (1-3 months). In this manual the fundamental aspects of culture systems and live food production essential to obtain black flounder larvae and juveniles of good quality are presented. Besides, skeletal malformations and pigmentation problems registered in juveniles and the culture methods employed to reduce the percentage of those anomalies are detailed. Black flounder (Paralichthys orbignyanus) larval culture demands a deep knowledge of its embryonic and larval development and of the nutritional and culture requirements of the different stages. The species can be fattened at high densities (100 juveniles m -2 ) in tanks with a recycling system up to marketable size with good growth (1.25 percent d -1 ) and survival rates (90 percent) and low levels of stress.
