The shrimp industry, including its culture and feed sectors, exhibited steady growth
over the years with a reduced cost–benefit ratio due to increasing production costs
attributed mainly to enhanced feed costs. The unsustainable availability and rapid
increase in fishmeal cost have forced the aquafeed sector to reduce dietary inclusion
levels. The filamentous fungus, Aspergillus niger plays an important role in utilising
plant protein sources for formulating cost-effective shrimp feed. A. niger has been
reported to produce numerous hydrolytic enzymes to degrade the limiting factors of
plant proteins such as antinutrients and fibre fractions. This fungus enhanced not
only the quantity but also the quality of proteins and amino acids, especially methionine and lysine. Likewise, it also increased the availability of soluble minerals, particularly phosphorous, by degrading the phytic-phosphorus, thereby helping to replace
dietary fishmeal up to 80% in penaeid shrimps. Consequently, this fungus could
reduce feed formulation cost significantly. However, the mycotoxins produced by
this fungus pose difficulties during large-scale fermentation, and its implications on
the workers and environment cast doubt about its efficacy and utility. However,
recent developments indicate that A. niger could be an alternative choice in reducing
the pressure on fishmeal demand by enhancing the nutrient utilization of plant-based
materials leading to the formulation of, cost-effective feeds that can sustain shrimp
culture and production in the future.
