“…Em relação ao desempenho dos alevinos, os resultados são apresentados na Tabela 2. Boscolo et. al (2008), efetivou experimentos objetivando avaliar o desempenho e a sobrevivência de larvas de tilápia do Nilo durante a fase de reversão sexual, utilizando-se de rações com níveis de inclusão de óleo de resíduos da indústria de filetagem de tilápias em substituição ao óleo de soja, concluindo que o mesmo pode substituir totalmente o óleo de soja neste processo.…”

RESUMOCom o aumento da produção de tilápia para a produção de filé, seus resíduos, farinha e óleo têm grande disponibilidade e preços competitivos. O presente experimento foi realizado com o objetivo de avaliar o uso de óleo de abatedouro de tilápia como fonte lipídica na alimentação de alevinos. Neste sentido, foram utilizados 200 alevinos, com peso individual aproximado de 0,6 ± 0,11 g aos quais foram fornecidas dietas com 6,52% de lipídeos, substituindo-se o óleo de soja, por óleo de abatedouro de tilápia (0, 25, 50, 75 e 100% de substituição), por 50 dias. Foram verificados os parâmetros de desempenho, composição de carcaça e teor de ácidos graxos no filé e nas vísceras. As diferentes porcentagens de substituição não influenciaram o ganho de peso, conversão alimentar e sobrevivência, mas a composição corporal foi afetada pela fonte lipídica nos teores de umidade e lipídeos. Os teores dos diferentes ácidos graxos refletiram os teores das dietas, com marcante incorporação dos ácidos graxos saturados e monoinsaturados característicos da gordura animal com as substituições. Desta maneira o óleo de tilápia pode substituir parcial ou totalmente o óleo de soja como fonte lipídica para alevinos de tilápia do Nilo.

“…This is due to its rapid growth and good quality meat (Furuya et al, 2008). In addition, because of its omnivorous feeding habit, tilapia easily accepts feed from the initial period to the termination phase (Boscolo et al, 2008).…”

“…Feeding is considered the main cost within an aquaculture sector, mainly in the intensive production of fish. The use of lipids in fish diet has the special advantage of being a low-cost energy supply (Boscolo et al, 2008;Juancey, 2000). In addition to providing substrates for energy production, lipids are sources of essential fatty acids and are structural components of cell membranes acting as transporters for other nutrients such as fat-soluble vitamins (Garcia et al, 2013).…”

“…Lipids play an important role in the growth phase of fish, being essential for their development, in which the use of vegetable oils becomes the main source of nutrients for this phase (Wilson, 1995;Hayashi et al, 2002;Boscolo et al, 2008;). It is observed that soy oil can be replaced by other vegetable oils without causing zootechnical damage, allowing compensatory animal gain (Nwanna & Bolarinwa, 2000i).…”

The objectives of this research were to evaluate the effects of the substitution of soybean oil by palm oil in the diet of Nile tilapia (Oreochromis niloticus) post-larvae, to observe the performance and attractiveness of the feed, and to evaluate the fatty acid methyl esters profile of palm oil. Four hundred Nile tilapias were used after hatching (seven days old), distributed in 20 fiberglass tanks of 20 L each. The experiment was carried out in a completely randomized design with five treatments and four replicates. The treatments consisted of different levels of inclusion of palm oil, which were: 0.0, 1.5, 3.0, 4.5 and 6.0 %. The concentration of monounsaturated and saturated fatty acids in palm oil was measured, resulting in high amounts of palmitic, oleic and linoleic fatty acids. Significant differences were observed for the variables final weight, total length, weight gain, specific growth rate and condition factor. No significant differences were observed for palatability of the diets. It is concluded that the inclusion of 3% or more palm oil in substitution of soybean oil during the masculinization stage of tilapia larvae contributes to the improvement of productive parameters.

Three trials were conducted to determine the effect of lipid sources on lambari reproductive and growth performances as well as to make the comparison in the fatty acid profiles in tissues of lambari wild and captive. For the reproduction and growth performances were provided since the larval stage until the reproductive period (11 months), three diets containing different sources of oil: soybean oil (SO); tilapia waste oil (IT); salmon waste oil (SA). During the reproductive period, fish (36 females and 72 males) were artificially induced to spawn and the reproduction parameters (volume and total number of eggs, fertilization and hatching rates, egg diameter and larval length) were evaluated, as well as monitoring of oocyte regeneration post-spawning. It were observed larger eggs and larvae and higher fertilization rate in the progeny of fish fed diets containing fish oil, which may be related to higher n-3/n-6 ratio values found in the eggs. For the trial of growth performance were used 192 sexed lambaris (male anal fin spines) with 120 males (mean weight 2.58 ± 0.13g) and 72 females (mean weight 4.00 ± 0.09g). The fish were separated on a random method in a factorial scheme 3 x 2, composed by three diets (SO, TI e SA) and two sexes. It was verified that females had higher weight gain, improved feed conversion and protein efficiency rates than males, which showed higher survival at the end of the trial, regardless of diet. In the third trial were collected 30 wild and 30 captive females. The lipids of tissues (muscle, liver and ovary) were extracted from each group and were separated (polar and non polar) and thus determined the fatty acids profiles. The results were analyzed by ANOVA and F test. The lambaris of both groups had mean of 3.5g.100g-1 in the muscle and the wild fish ovaries showed the highest concentration of lipids (14.447g.100g-1) than farming fish (13.181 g.100g-1). The diet failed to supply the minimum amount of important fatty acids in fractions and total lipids of cultivate females and these evidences were higher in the ovaries. Linolenic acid which is considered essential for freshwater fish, was present in smaller amounts in total lipids and polar and nonpolar fractions in all tissues of the cultivated lambari, which may be related to default in commercial diets for omnivores fish. In view of parameters observed in reproduction and growth trials, it can be suggest the inclusion of waste tilapia and salmon oil in lambari broodstock diet. Also it was observed that lambaris have the capacity elongation and desaturation of fatty acids with 18 carbons in the chain for the Arachidonic Acid (AA), Eicosapentaenoic Acid (EPA) and Docosahexaenoic Acid (DHA) production due to low amount of these fatty acids in the diet and the increase in the tissues.
