“…With respect to growth, the result of the present study corroborates with reports in the literature that lipid increase at an adequate level can improve fish growth, since requirements as to energy and, mainly, essential fatty acids, such as α-linolenic acid, are met (Ikeda et al, 2011). Flaxseed oil with a high dietary content increased α-linolenic acid (n-3) in the diet, positively impacting the growth of the zebrafish, possibly showing the animal's high capacity to digest and absorb this component.…”

Flaxseed oil is recognized as the plant source richest in α-linolenic acid, whereas clove leaf essential oil has a strong antioxidant capacity. The objective of this study was to determine the in vitro antioxidant capacity of diets containing a combination of flaxseed oil (FO) and clove leaf essential oil (CLEO), as well as to use zebrafish (Danio rerio) to assess their effect on the animals’ growth. Fifty days after hatching, a total of 420 male specimens (0.29 ± 0.04 g) were divided into seven groups for each diet and fed for 55 days to be used, with the diets being: control, absent FO and CLEO; 3% FO + 0.5% CLEO; 3% FO + 1% CLEO; 6% FO + 0.5% CLEO; 6% FO + 1% CLEO; 9% FO + 0.5% CLEO and 9% FO + 1% CLEO. Antioxidant activity was determined through DPPH (2,2-diphenyl-1-picrylhydrazyl) tests, showing interaction effect between factors (FO x CLEO, p < 0.05); the diets containing 1% combined with 3, 6 or 9% of FO presented means higher than those of the 0.5% diets. No mortality was observed during the experiment. For final weight and weight gain, there was no interaction effect (p > 0.05), only isolated effect for FO, with the fish fed 6 and 9% diets having the best results. Final total length and specific growth rates showed interaction effect (p < 0.05). As for specific growth rates, the best response was that of the diet with 6% FO and 0.5% CLEO. Final length showed increase with FO levels, even when there was association with 0.5 or 1% of CLEO. Therefore, combined use of 9% of FL with 0.5% of CLEO is recommended for zebrafish.

“…These results corroborate those of Sagne et al, (2013) who obtained the best FCR with diet E (equal proportion of peanut oil and soybean oil) with a FCR of 1.37 versus 1.77 for regime A (100% HP). However, they are similar to those of Kamarudin et al, (2011) who found FCRs ranging from 1.6 to 1.9 in his study on the effects of the replacement of food fish oil by different sources of food, Vegetable oil on the growth performance and tissue fatty acid profiles of Tor tambroides juveniles.…”

To investigate the effects of replacement of fish oil by a mixture of Balanites aegyptiaca and Adansonia digitata seed oils three isonitrogenous (35.36%) and isoenergetic diets (3.48 MJ / kg) were formulated for one kilogram (1kg). The study was carried out on fries Clarias anguillaris for six weeks.At the beginning of the experiment, 90 Clarias anguillaris of the initial average weight of 0.82 ± 0.055g were randomly divided into three different groups with two replicates containing 15 fish/each. Fish were kept in six plastic tanks (50 x 40 x 30 cm) container (50 L). The results showed that the substitution of fish oil by a mixture of Balanites aegyptiaca seed oil and Adansonia digitata seed oil gives growth for all diets. However, the best growths are obtained from all points of view (MWGr, MWGa and SGR) with diet A (mixture of Adansonia seed oil and Balanites seed oil at a ratio of 20 : 20) followed by the diet D (mixture of Adansonia seed oil and Balanites seed oil at 10 : 30) compare to the control diet M containing fish oil. The best FCR was observed with the diet A followed by the diet D compare to the FCR observed with the diet M. The PER was higher in diet A (0.57) followed by diet D with (0.45) that has no significant difference with the control diet M (0.43). The highest value 63% was obtained with the diet D followed by 60% with the diet M and finally the lowest value 53% was obtained with the diet A. In regards to the growth performance, fish fed a 100% vegetable oil diet showed the best growth performance. Therefore, the replacement of fish oil with a mixture of Balanites aegyptiaca seed oil and Adansonia digitata seed oil has no negative impact on the growth of Clarias anguillaris fry. It would be interesting first to study the inclusion rate of Balanites aegyptiaca seed oil for a partial replacement of fish oil.

“…The effect of dietary lipids on CT max and lethal thermal limits has also been assessed in a handful of studies, with mixed results. Oil type did not influence upper thermal limits in juvenile angelfish [56], but total lipid composition (10 versus 20%) had a significant effect on CT max in juvenile barramundi [31]. The effect of dietary fats on cardiac thermal plasticity in fish is relatively unknown.…”

Diet changes thermal acclimation capacity, but not acclimation rate, in a marine ectotherm (Girella nigricans) during warming

Global climate change is increasing thermal variability in coastal marine environments and the frequency, intensity and duration of marine heatwaves. At the same time, food availability and quality are being altered by anthropogenic environmental changes. Marine ectotherms often cope with changes in temperature through physiological acclimation, which can take several weeks and is a nutritionally demanding process. Here, we tested the hypothesis that different ecologically relevant diets (omnivorous, herbivorous, carnivorous) impact thermal acclimation rate and capacity, using a temperate omnivorous fish as a model (opaleye, Girella nigricans ) . We measured acute thermal performance curves for maximum heart rate because cardiac function has been observed to set upper thermal limits in ectotherms. Opaleye acclimated rapidly after raising water temperatures, but their thermal limits and acclimation rate were not affected by their diet. However, the fish's acclimation capacity for maximum heart rate was sensitive to diet, with fish in the herbivorous treatment displaying the smallest change in heart rate throughout acclimation. Mechanistically, ventricle fatty acid composition differed with diet treatment and was related to cardiac performance in ways consistent with homoviscous adaptation. Our results suggest that diet is an important, but often overlooked, determinant of thermal performance in ectotherms on environmentally relevant time scales.
