Dietary arachidonic acid promotes growth, improves immunity, and regulates the expression of immune-related signaling molecules in Macrobrachium nipponense (De Haan)

Thoughts for the Future of Aquaculture Nutrition: Realigning Perspectives to Reflect Contemporary Issues Related to Judicious Use of Marine Resources in Aquafeeds

“…; Ding et al. ). Accordingly, a much greater effort into basic research to define individual requirements for key fatty acids—nutrients rather than raw materials—and elucidate their specific roles in aquatic animal health and optimal performance is needed.…”

“…Previous lipid nutrition research, relying primarily on traditional terrestrial and marine oils, assessed essential fatty acid requirements in terms of total n-3 or n-6 fatty acids. Now, mounting evidence suggests that the different n-3 LC-PUFAs vary substantially in their nutritional value, n-6 LC-PUFAs are also nutritionally important, and the functional differences between C 18 PUFAs and LC-PUFAs have not been adequately communicated (Glencross and Smith 2001;Koven et al 2001;Bell and Sargent 2003;Van Anholt et al 2004;Lund et al 2007;Norambuena et al 2015;Ding et al 2018). Accordingly, a much greater effort into basic research to define individual requirements for key fatty acids-nutrients rather than raw materials-and elucidate their specific roles in aquatic animal health and optimal performance is needed.…”

Effects of dietary lipid levels on the growth, fatty acid profile and fecundity in the oriental river prawn,Macrobrachium nipponense

“…These phenomena have become prevalent with the expansion of production scale (Jiang et al, ). Sexually precocious M. nipponense has a tendency of small size, poor survival, slow weight gain and short life span owing to captivity or inappropriate nutrition which seriously restricts the aquaculture development of this species (Ding et al, ; Wu et al, ). Furthermore, the adverse effects of sexual precocity on reproductive performance and offspring quality of female M. nipponense are particularly prominent.…”

“…To raise the phospholipid levels in the diet could result in enhanced lipid deposition and increased energy availability for growth and ovarian development (Wu et al, ). Highly unsaturated fatty acids (HUFAs) are known to play important roles in controlling and regulating cell membrane fluidity, signalling pathways, fatty acid β‐oxidation, growth performance, lipid metabolism, pigmentation and egg quality of broodstock in shrimp (Ding et al, , ; Jin et al, ; Luo et al, ; Wu et al, ). In some cases, increasing digestible lipid supplementation in feed has shown a protein‐sparing effect, protein utilization efficiency improvement, as well as nitrogen losses reduction to the environment (González‐Félix, Gatlin, Lawrence, & Perez‐Velazquez, ).…”

Effects of salinity acclimation on the growth performance, osmoregulation and energy metabolism of the oriental river prawn, Macrobrachium nipponense (De Haan)

“…The annual artificial aquaculture production of M. nipponense has exceeded 200,000 tons, with an output value of 2 billion RMB (Bureau of Fisheries, ). Previous studies on M. nipponense mainly focused on nutrition regulation (Ding et al., ; Gu et al., ), germplasm resources (Cui, Yu, Bao, Wang & Xiao, ; Fu et al., ) and immune performance (Li et al., ; Tang, Ji, Yang, Liu & Xie, ); few studies have reported the effects of different salinities on the growth mechanism of M. nipponense . The use of seawater species for desalination culture and freshwater species for saltwater acclimation has become a new trend in the aquaculture industry (Nikapitiya, Kim, Park & Kwak, ; Shekhar, Kiruthika & Ponniah, ; Silva, Calazans, Soares, Soares & Peixoto, ; Xu et al., ).…”
