A system that supplies water of good quality is an essential factor
if we want to obtain good welfare and growth, and reduce stress and
risk of disease outbreaks. Especially in closed recirculation systems,
where there is little or no exchange of water, a build-up of toxic
metabolites and reduction in oxygen concentrations may happen
very rapidly (Timmons and Losordo, 1994). However, in land-based
profitable lobster farming, re-circulation of water is necessary to
reduce heating costs. Thus, in any occasion, it is important to understand
what the optimal as well as limiting culture conditions are for lobsters.
