“…The "critical window" is an extremely crucial aspect of nutritional programming. For mammals, it is mostly during gestation or lactation, while for fish, it is usually during the egg or larval stage, or during the spawning season (broodstock) (11) . For fish, the embryonic and larval stages are characterized by organogenesis, establishment of metabolic pathways, and strong metabolic plasticity (17) .…”

The nutritional status experienced in the early development of life plays a vital role in the long-term metabolic state of the individual, which is known as nutritional programming. The present study investigated the long-term effects of vegetable oil (VO) nutritional programming during the early life of large yellow croaker. This study aimed to promote the utilization of VO in juvenile fish and alleviate the negative effects of VO through VO nutrition programming. First, larvae were fed either a fish oil (FO) diet or a VO diet for 30 d (the two groups named F and V, respectively). Subsequently, under the same conditions, all fish were fed a commercial diet for 90 d (the two groups named FC and VC, respectively) and thereafter challenged with an FO or VO diet for 30 d (the three groups were named FCF, FCV, and VCV, respectively, in the challenge phase). The results showed that the growth performance was significantly lower in larvae fed the VO diet (F: 16.54 mg) than in those in fed the FO diet (V: 17.50 mg) in the stimulus phase. Notably, VO nutritional history fish showed lower levels of liver lipids (FCV: 64.23%, VCV: 60.69%), liver total triglycerides (FCV: 106.82 mmol/g, VCV: 74.71 mmol/g) and serum nonesterified free fatty acids (FCV: 0.67 mmol/L, VCV: 0.50 mmol/L) than the FO nutritional history fish when juveniles were challenged with the VO diet, which was consistent with the expression of lipogenesis-related genes (srebp1c, dgat1, acc1, and fas) and proteins (SREBP1c, DGAT1, and ACC). Moreover, the VO nutritional history fish showed lower liver damage and higher antioxidant capacity than FO nutritional history fish when challenged with the VO diet. In summary, this study showed that a short VO stimulus during the early life stage of large yellow croaker, had a long-term effect on lipid metabolism and the antioxidant system. Specifically, VO nutritional programming had a positive effect on alleviating abnormal lipid deposition on the liver, liver damage, and the reduction of hepatic antioxidant capacity caused by a VO diet.

“…Furthermore, given the ability of both viable and non-viable lactobacilli to stimulate fish immunity and infection resistance [63], lactobacilli enriched feed granules could have added probiotic value for larval fish. This opens the way for eventual application of lactobacilli for improvement of nutrient availability in lower quality, animal by-product based, larval feed [64, 65, 66], which would minimize the costs associated with larval rearing without profit reduction.…”

Solid state treatment with Lactobacillus paracasei subsp. paracasei BGHN14 and Lactobacillus rhamnosus BGT10 improves nutrient bioavailability in granular fish feed

The aim of this research was to improve nutritive value of fishmeal-based feed by lactobacilli in order to achieve satisfactory nutrient availability needed to support fish development. Feed was solid-state treated at a laboratory scale with the combination of Lactobacillus paracasei subsp. paracasei BGHN14 and Lactobacillus rhamnosus BGT10 in different experimental settings, which included the variation of strain ratio, total lactobacilli concentration, percentage of moisture and duration of incubation. Short peptides, soluble proteins, phospho-, neutral and unsaturated lipids were quantified. Differences among treated and control feeds were evaluated by Student t-test, while Gaussian process regression (GPR) modeling was employed to simulate the incubation process and define the optimal treatment combination in the context of overall feed nutritional profile. Treatment duration was shown to be the critical determinant of final outcome, either as single factor or via interaction with strain ratio. Optimal nutrient balance was achieved with 12 h incubation period, 260% moisture, 75:25 and 50:50 BGHN14:BGT10 ratios and 200 mg of lactobacilli per g of dry feed. This study should serve as the basis for large-scale tests which would simulate on-farm production of both fishmeal-based and unconventional, lower cost aquafeed with added value.

“…However, the size of the fish mouth, gut capacity, acceptance, and digestibility of microdiets are bottlenecks for larval culture [5,6,12]. Generally, microdiets are administered after the larval fish are reared with live food [11] or in combination with live food.…”

Protein is an essential nutrient that supports fish growth, and the inadequacy in formulating their diets with an optimum protein level can deteriorate their growth performance. The protein requirement in granulated microdiets was estimated for rockfish (Sebastes schlegeli) larvae. Five granulated microdiets (CP42, CP46, CP50, CP54, and CP58) containing 42% to 58% crude protein levels with a 4% increment at a constant gross energy level (18.4 kJ/g diets) were prepared. The formulated microdiets were also compared with imported microdiets, Inve (IV) and love larva (LL) from Belgium and Japan, respectively, and a locally marketed feed (crumble). At the cessation of the study, the survival of larval fish was not different ( P > 0.05 ), but the weight gain (%) of fish fed the CP54, IV, and LL diets was significantly ( P < 0.0001 ) higher than that of larval fish fed the CP58, CP50, CP46, and CP42 diets. The crumble diet achieved the poorest weight gain of larval fish. Furthermore, the total length of rockfish larvae fed the IV and LL diets was significantly ( P < 0.0001 ) longer than that of the fish fed all other diets. The chemical composition of the fish’s whole body, except for ash content, was not influenced by the experimental diets. The experimental diets affected essential amino acid profiles, such as histidine, leucine, and threonine, and nonessential amino acid profiles, such as alanine, glutamic acid, and proline of the whole body of larval fish. Conclusively, based on the broken line analysis of weight gain of larval rockfish, protein requirement in granulated microdiets was estimated to be 54.0%.
