Broodstock management, the control of reproduction are essential aspects to the development of sustainable culture of species new to aquaculture. The capture and acclimation of wild fish destined as broodstock for a species new to aquaculture presents challenges that must be overcome to achieve the level of reproductive control necessary for aquaculture. The culture environment has c ritical points that are species specific factors that affect maturational development and which include: forming a broodstock, the captive environment, fish welfare, nutrition, the environment during gametogenesis and the environment during final maturation and ovulation / spermiation. Failure to adequately address these critical factors can lead to reproductive dysfunctions and reduced fecundities and egg quality. A range of bio-technological tools have been developed to address these reproductive dysfunctions. These bio-technologies offer simple solutions essentially, controlling the environment to provide the cues necessary for maturational development or the use of hormone therapies to induce the different aspects of gametogenesis to provide the spawning or stripping of high quality gametes.
W ork in IRTA has focused on reproductive control of new and emerging aquaculture species. Examples of this work will be used to demonstrate the possible out comes of applying different bio-technologies to overcome reproductive dysfunctions that limit the development for culture of new and emerging aquaculture species.
