The experimental results suggested that T-4 (treatment where fishmeal 100%% replaced by poultry viscera) can be recommended for the intensive culture of A. testudineus.
Valle et al. (2015), replaced fish meal with biofloc flour and protein hydrolysate in the diet of L. vannamei and indicated that biofloc flour is a potential ingredient that can be used as substitute for fishmeal.
Critically, growth in demand for conventional protein sources has driven up the prices of both commodities (soy: 88 %, fishmeal: 165 % over the last decade), and this long-term trend can be expected to continue.
Bart Muys, an ecologist at KU Leuven in Belgium, tells the conference-goers that although insects can be reared on relatively tiny plots of land, producing insect meal requires significantly more energy than fishmeal or soymeal does, largely because the bugs need to be raised in warm conditions.
A detailed dietary composition can be found in Tables 1 and 2.> -wrap-foot>> drydry matter, SM soybean meal, FM fishmeal, NFC non-fibre carbohydrate The following are presented as % DM: CP, ADF, NDF, lignin, crude fat and NFC.
Animals that are fed fishmeal can bioconcentrate monomethyl mercury in protein matrices that are then passed on to the consumer in the fat components of derived foods [ 15].
In a perfect bit of carnivorous symmetry, pigs and poultry can also be fed on fishmeal.
But when kahala are isolated away from reefs and fed a traditional aquaculture diet of soy and fishmeal, they are ciguatera-free.
However, feed efficiencies were similar, indicating that the increased weight gain of the fish on the fishmeal diet was the result of consuming more feed.
