Resumo:
The great demand for ingredients with high protein content and lower production cost
as an alternative to supply the use of fish meal in aquaculture feed formulations, means
that new sources of animal protein can be studied, including insect meal. Insects have
been considered a promising source of nutrients for aquatic organisms, offering an
alternative to scarce or unsustainable conventional foods, which represent the highest
cost in fish farming, ranging from 65% to 80% of total costs. In this context, the search
for nutritious and viable ingredients that can reduce the cost of the feed without
compromising the growth of the fish has been the subject of several studies. In this
sense, this work aims to elaborate flours originating from four species of insects:
cinerea cockroach, Madagascar cockroach, black cricket and tenebrio larvae, which
have shown potential to be used in the formulation of feeds for different species of fish,
the from the dehydration process. The insects were acquired frozen in a biofactory in
Recife-PE, duly registered and that meets the requirements in the creation of insects
intended for human consumption. The work was carried out at the Fish and
Aquaculture Studies Laboratory (LAPEAq) and at the Fishing Unit (CES/UFCG), where
the meals were produced. The parameters observed in these studies were: Dry matter
(DM), Moisture, mineral matter (DM), Crude protein (CP) and Ethereal extract (EE),
which were analyzed at the Food and Animal Nutrition Laboratory of the Center for
Agricultural Sciences at UFPB (CCA/UFPB). As for Dry Matter (DM) and Humidity,
there was no significant difference between the flours studied, Mineral Matter (MM)
and Crude Protein (CP), Madagascar Cockroach has the highest amount compared to
other insects, and Ethereal Extract (EE) the tenebrio larvae and the cineréa cockroach
have the highest levels. Therefore, it is concluded that the use of insects in aquaculture
nutrition is viable and promising in terms of cost/benefit, aiming at a greater
zootechnical development of the animals and the sustainability of the production chain,
with emphasis on fish farming.
