“…Our results also show the importance of DHA supplementation in BT-based diets on enhancing growth performance and feed utilization and ensuring the desired levels of DHA in the whole fish. Similar results were also reported in a previous study conducted on Florida pompano, Trachinotus carolinus, showing that fish fed the DHA-supplemented feeds that replaced FO with BT exhibited the best performance in growth among the tested feeds (Rombenso, Trushenki, & Schwarz, 2017).…”

“…Similar findings were also observed in the subadult olive flounder fed diets containing different lipid sources and levels (Kim et al, 2012). This can be supported by findings in other fish species such as Florida pompano and Atlantic salmon showing that the total lipid content of fillet was not affected by the replacement of FO with BT (Emery et al, 2014;Rombenso et al, 2017). In this study, it was demonstrated that the growth performance, whole-body nutrient composition, and plasma parameters were largely unaffected by the lipid substitution; however, the fatty acid profile of whole fish was altered.…”

This study evaluated the effects of replacing fish oil (FO) with beef tallow (BT) in juvenile olive flounder, Paralichthys olivaceus (3.93 ± 0.07 g), over 8 weeks. Seven diets, consisting of 0, 25, 50, 75, and 100% replacement of FO with BT and 63 and 75.9% replacement supplemented with docosahexaenoic acid (DHA) at 0.9 and 1.1% of 100 g diet, respectively, were distributed into 21 tanks in a semi-recirculation system with 15 fish per tank. The replacement of FO with BT at the given levels showed no significant changes (p > .05) in growth performance and whole-body proximate composition. Fish fed the diet of 75.9% replacement with 1.1% DHA supplementation showed the best performance in these measurements among the treatments. Plasma glutamic pyruvic transaminase, cholesterol, highand low-density lipoproteins, and total protein were not significantly influenced by the replacement of FO with BT. The FO replacement generally resulted in a reduction of eicosapentaenoic acid, DHA, and n-3/n-6 polyunsaturated fatty acid ratio in the whole body, whereas the DHA supplementation Seunghyung Lee and Frolan A. Aya contributed equally to this work.

“…With the expected wide adoption of cobia pelleted and extruded feeds, the next step in improvements to the sustainable expansion of cobia culture in Brazil, embraces lowering fishmeal and fish oil content by adopting alternative proteins and lipid sources, including soybean meal and oil, rapeseed oil, palm oil, poultry-by meal and fat, pork lard, beef tallow among other animal or plant ingredients, with proven suitability without production nor nutritional impairment (Betancor et al, 2016;Rombenso et al, 2017;Suarez et al, 2013;Trushenski et al, 2012;Watson et al, 2014;Woitel et al, 2014).…”

Cobia is one of the most promising warm water aquaculture species. In Brazil, cobia farming began in 2008 in the state of Rio de Janeiro from experimental scale facilities to regular near-shore farms based on fresh/frozen fish diets composed mostly of Sardinella sp. Despite the encouraging results achieved in the promotion of sustainable cobia farming, we advocate the replacement of fresh/frozen fish by a practical formulated feed. This experiment evaluated the zootechnical performance and environmental efficiency of moist and practical formulated feeds in early grow-out phases in the cycle of cobia nearshore cage culture. Four hundred and twenty juvenile cobia (151 ± 7 g) were fed with moist feed and practical formulated feed for 56 days. Biometrics were taken every two weeks and diets were analyzed for proximate composition, fatty acid composition and pellet quality. Although growth performance was equivalent between treatments, feed consumption and feed conversion ratios (FCR) were different (p < 0.05) and varied according to water temperature. Cobia fed moist feed exhibited an FCR two times higher than those fed formulated feed. Elevated settling speed and low floatability contributed to higher heterogeneity and lower efficiency of fish fed moist diet. Nitrogen excretion rate was reduced (64 %) and protein efficiency ratio elevated (27 %) within formulated diet groups in comparison to those fed moist diet (79 % and 15 %, respectively). The fatty acid profile of cobia muscle was similar across the groups. With no negative effects of diet substitution on production performance and improvement of environmental efficiency, this approach can be applied and advocated globally and contribute to the responsible intensification of sustainable marine fish culture.

“…Rendered beef tallow has been used alone or in addition to EPA, DHA or EPA + DHA to partially or completely replace FO in aquafeeds for Florida pompano of 41 average initial weight (Rombenso et al . ). Fish meal provided half of the dietary protein in all of the experimental diets.…”

Marine tropical carnivorous (MTC) fish are less tolerant to high dietary lipid compared with cold and temperate climate fish. However, insufficient n-3 longchain (≥C 20 ) polyunsaturated fatty acids (LC-PUFA) compromises MTC fish health and growth which requires attention when choosing lipid sources in aquafeed formulations. Fish oil (FO) has been the major lipid source for feeding key MTC fish. We estimated that more than 200 thousand tonnes of FO were used to feed farmed MTC fish in 2016, representing nearly 25% of global FO production. Nevertheless, recent increases in FO prices and demand, and the foreseen inability of wild fisheries to produce sufficient FO in the future, have created a need for cheaper and more sustainable alternatives. Meta-analysis showed that feeding vegetable oils (VO) to MTC fish can slightly reduce their growth, with a marked decrease in n-3 LC-PUFA content in the fish tissues corresponding with the increased replacement of FO and fishmeal in the diet. Rendered terrestrial animal fat or modulating the bioconversion of n-3 LC-PUFA precursors in VO can be utilised further in MTC fish nutrition with more research recommended on these approaches. Oils and oil-rich meals from non-food marine organisms are rich in n-3 LC-PUFA and represent an underutilised alternative to FO for tropical aquaculture. With oils rich in n-3 LC-PUFA produced from transgenic plants presently gaining regulatory approvals and becoming available as a renewable alternative to FO, aquaculture in the tropics and around the globe is ready to leap into a new phase of sustainable expansion.
