Biología reproductiva del lenguado Paralichthys orbignyanus: Maduración y potencial reproductivo en ejemplares cultivados y salvajes
MetadataShow full item record
Intensive culture of teleost fish introduces changes over the environmental conditions found in their spawning grounds, leading to reproductive dysfunctions. The manipulation of these parameters (photoperiod, temperature) represents a common technique to alter the reproductive rhythms and enhance the spawnings in terms of quality and quantity. Nevertheless, for each species some modifications or adjustments have to be done according to their reproductive strategies. The advantages of manipulating those parameters are primarily to schedule the spawning for a desired period of time and to obtain good quality and quantity eggs. Many factors such as tank dimension, light intensity, nutritional status and husbandry of broodfish and minimum stress level have been proved to greatly influence the reproductive behavior and the production of eggs of Paralichtys orbignyanus broodstock. The reproductive peak for this species under controlled conditions occured between October and February, when te.....
