Ontogeny and Systematics of Fishes e-bog

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Subsequently a number of factors have been identified to add to our corpus of knowledge on rearing. These include the need for good water quality, with the interesting idea of green water culture of larvae in fairly high densities of Chlorella which seems to damp out fluctuations in metabolites, and perhaps enhance oxygenation as well as providing secondary feeding for the larvae Houde, 1977; Morita, Adequate light for visually feeding larvae and the need to prevent excessive bunching of larvae or their prey are also important, as is the quality of the food. Success or failure may now depend on the fatty-acid profile of the Artemia nauplii which are still used by most workers in the later stages of rearing. Artificial diets of encapsulated or particulate food are also being developed but have yet to be introduced as a standard technique for early rearing.
