Abstract
The development of cost-effective and nutritionally adequate formulated feeds is
a key step for developing sustainable technologies for new aquaculture species.
There has been many research effort for over 30 years on feed development for
spiny lobsters, but amazingly, poor performance of formulated feeds remains one
of the major obstacles to progressing commercial aquaculture of these crustaceans.
This is partially due to a lack of information on how spiny lobsters digest
and assimilate formulated feeds. The aim of this review is to integrate recent
information on the digestive physiology of spiny lobsters to identify areas where
further studies are needed for advancing to more physiologically tailored formulated
feeds. Increasing the efficiency of mechanical and chemical digestion is
imperative for better digestion of formulated feeds. This is likely to be achieved
by improving feed format, reducing the particle size of ingredients, using digestible
binders, preprocessing or selecting more soluble macronutrients and supplementing
feeds with additives such as pH buffers, emulsifying agents and/or
exogenous enzymes. Future research needs to adopt a holistic approach for investigating
the digestive processes in spiny lobsters by focusing on digestion as well
as downstream processes. The protein-sparing effect of lipids and carbohydrates
on spiny lobster metabolism is of a particular significance as the spiny lobster
metabolism is strongly directed towards the use of protein. This review provides
important insights, practical solutions and key research directions to improve
both our understanding of spiny lobster digestive physiology and the performance
of formulated feeds for spiny lobsters.
