Recent research has revealed the significant impact of novel feed ingredients on fish gut microbiota, affecting both the immune status and digestive performance. As a result, analyzing the microbiota modulatory capabilities may be a useful method for assessing the potential functionality of novel ingredients. Therefore, this study aimed to evaluate the effects of dietary polychaete meal (PM) from Alitta virens on the autochthonous and allochthonous gut microbiota of European seabass (Dicentrarchus labrax). Two diets were compared: a control diet with 25% fishmeal (FM) and a diet replacing 40% of fishmeal with PM, in a 13-week feeding trial with juvenile fish (initial weight of 14.5 ± 1.0 g). The feed, digesta, and mucosa-associated microbial communities in fish intestines were analyzed using high-throughput sequencing of the 16S rRNA gene on the Illumina MiSeq platform. The results of feed microbiota analyses showed that the PM10 feed exhibited a higher microbial diversity than the FM diet. However, these feed-associated microbiota differences were not mirrored in the composition of digesta and mucosal communities. Regardless of the diet, the digesta samples consistently exhibited higher species richness and diversity than the mucosa samples. Overall, digesta samples were characterized by a higher abundance of Firmicutes in PM-fed fish. In contrast, at the gut mucosa level, the relative abundances of Mycobacterium, Taeseokella and Clostridium genera were lower in the group fed the PM10 diet. Significant differences in metabolic pathways were also observed between the FM and PM10 groups in both mucosa and digesta samples. In particular, the mucosal pathways of caffeine metabolism, phenylalanine metabolism, and sulfur relay system were significantly altered by PM inclusion. The same trend was observed in the digesta valine, leucine, and isoleucine degradation and secretion pathways. These findings highlight the potential of PM as an alternative functional ingredient in aquafeeds with microbiota modulatory properties that should be further explored in the future.

“…Final length mainly for treatment A (2.84±0.11 mm) was suitable size for stocked in pond and SGR relatively higher compared with larvae fed that contained polychaeta (Nereis sp.) meal into the diet [37]. A study on higher fry density up to 30 fish Lhave been reported, however salinity media still low and maximum 2 ppt [10].…”

Provision of suitable technique for saline tilapia seed is required since demand of these species increased continuously. Most saline tilapia seed rely on sourcing freshwater fingerling and further acclimatized in brackishwater ponds. The study aimed to evaluate the effects of various fry densities on seed production parameters of tilapia under high salinity-biofloc system. Three fry densities being tested and cultured under biofloc technology (BFT) at salinity level above 20 ppt, such as: A (BFT 2.5 fry L−), B (BFT 5.0 fry L−), C (BFT 7.5 fry L−) and one treatment as control, D (Non-BFT 2.5 fry L−). The experimental set-up was completely random design and triplicated replications. Animals test were fed two times a day of 32% crude protein content and it was lasted for three weeks. Results from the experiment shown that treatment A (BFT 2.5 fry L−) performed best in term of biomass (18.00±3.61g), survival (98.00±2.00%), SGR (20.72±0.20% d−), FCR (1.72±0.38) and CF (1.59±0.17). An increasing stocking density up 7.5 fry L− will reduced survival rate, final individual weight and increased FCR. It can be concluded that production of tilapia seed at a density of 2.5 fry L− under BFT conditions performed healthy seed and best production parameters even reared at higher salinity.

High stocking density is an important factor in cultivation to increase the eficency if fish farming for nutrition requirements. High stocking density generally impact on fish physiology and growth performance. However, many studies on individual fish have different growth perfromance from different strain. Some technology had been developed to optimize tilapia production in high stocking density. This study aimed to determine the growth performance of three different strain of tilapia (red tilapia, nirwana tilapia, and jatimbulan tilapia) reared in 20 m3 of round tarpaulin with additional of microbubble generator. This study used an intensive system with 100 fish/m3 of stocking density. The results showed that the microbubble generator was able to increase the carrying capacity of water quality such as increasing dissolved oxygen in the waters, temperature and pH. The high content of dissolved oxygen in the water significantly increasing the growth of tilapia. The highest weight was found in red tilapia with a final weight of 199.56 ± 0.05 gr, followed by Nirwana tilapia with 176.59 ± 0.10 gr, and Jatimbulan tilapia with 153.91 ± 0.06 gr. In addition, the high content of dissolved oxygen in the waters also affect the rearing period of tilapia.
