Proceedings of the Zoological Society 2014 highlight this
review organised by Sudeshna Sen Roy and Ruma Pal on Microalgae biotechnology.
Clearly this item has gained considerable importance in
recent decades and its use is extending day by day into several areas like
nutraceuticals research, renewable energy source, production
of essential biomolecules like β-carotene, astaxanthin, PUFA, bio colorant
production, wastewater treatment, bioremediation and aquaculture
etc.
Among all of these, microalgae as a source of nutrition has long
drawn the attention and are widely used in animal nutrition. Fishmeal is the
preferred protein ingredient of feed in aquaculture industry, contributing
significantly to the variable production cost, but, decreasing fishmeal supply
and increasing costs posts threats to the sustainability and growth of the
aquaculture industry.
The assumption, therefore, complete or partial substitution
of fishmeal with alternative proteins is needed to solve the problem.
Presently, microalgae are used worldwide as an alternate protein source
replacing fishmeal successfully.
In feeding trials with fish, many types of microalgae have
been found to be used for increasing growth (protein accretion), feed
utilization, physiological activity, stress response, starvation tolerance,
disease resistance, and carcass quality.
This review is an attempt to review the application of
different microalgae in rearing of aquaculture animal especially the fishes.
