Four diets with 50% crude protein were formulated using fish meal, soybean meal and poultry offal meal as sources of protein. The control diet had 64% fish meal. The other three diets had 30, 20 or 10% fish meal with

Two species of decapod (Macrobrachium intermedium and Penaeus plebejus) were abundant in Z. capricorni. Four species (M. intermedium, P. plebejus, Chlorotocella leptorhynchus and Nectocarcinus tuberculosus) were abundant in P. australis. Abundance of all these species fluctuated greatly among sites and through time. Some seasonal patterns in abundance were evident, and appeared to be caused by recruitment and subsequent mortality or migration of individuals. Similarly, there were some consistent spatial patterns in abundance of most species. In particular, some sites supported consistently more juveniles during the same period of separate years. Within Jervis Bay, P. australis was also sampled in shallow (1-2 m) and deep (7-8 m) water. Three species were abundant (C. leptorhynchus, N. tuberculosus and Processa australiense), but showed no consistent differences between the two depths. Abundances of these species did fluctuate greatly among the sites within Jervis Bay and through time. Such observations of the natural rates of change in abundance of populations are essential in order to be able to detect the effects of human disturbances.

Together, fisheries and aquaculture provide 4.3 billion people with ~15% of their average per capita intake of animal protein. By 2050, an additional 75 million tonnes of fish will be needed to help feed more than 9 billion people. The recent revolution in aquaculture, and continued improvements to management of capture fisheries, have potential to provide the additional fish required. However, warming of the world’s ocean could disrupt these important initiatives. Ocean warming will result in ‘winners’ and ‘losers. Changes in distributions of fish stocks as species seek their optimal temperatures, and as the habitats on which they depend are altered by higher water temperatures, will result in decreases in fisheries production in some countries and increases in others. Similarly, the prime locations for mariculture are expected to be altered by ocean warming, resulting in changes in y...
