“…In addition, a study indicated that increasing the dietary lipid level influenced the total lipid composition of shrimp, by increasing lipid deposition in hepatopancreas and muscle tissue (González-Félix et al, 2002). Likewise, result was also supported by observations of many other previous studies in shrimps (Jannathulla et al, 2019;Xie et al, 2019;Zhu et al, 2010). Whole-body moisture, protein and ash contents were not significantly affected by the dietary lipid level in the present study.…”

A feeding trial was performed for 60 days to determine the dietary lipid requirement of Penaeus vannamei juveniles reared in inland saline water (ISW) of 10 g/L salinity. Six iso-nitrogenous (360 g/kg crude protein) and heterocaloric (15.4-17.6 KJ DE/g) semipurified diets were prepared with graded level of lipid viz., 20, 40, 60, 80, 100 and 120 g/kg (L2-L12 with 20 g/kg incremental level). Two hundred and seventy P. vannamei juveniles (5.51 ± 0.01 g) were randomly allocated (15 shrimps/200 L) into six treatment groups in triplicate following a completely randomized design. The shrimp of L4 and L6 groups exhibited significantly higher per cent weight gain (WG%), specific growth rate and protein efficiency ratio and the lowest feed conversion ratio.The lipid efficiency ratio and hepatopancreatic somatic index were significantly decreased and increased with increasing levels of lipid respectively. The L6, L8 and L10 groups exhibited significantly higher (p < .05) lipase activity. Shrimp of higher dietary lipid fed groups exhibited significantly higher (p < .05) aminotransferase activity than their lower dietary lipid fed counterparts. Based on WG% data, broken-line linear and second-order polynomial regression analysis showed that the optimal dietary lipid requirement of P. vannamei in ISW of 10 g/L salinity was 46.5 and 51.4 g/kg respectively.

A feeding experiment (60 days) was conducted to evaluate the effect of Bacillus spp. fermented plant protein mix in Penaeus monodon. A control diet (CNT) contains 25% fishmeal, of which 50% was substituted (w/w) with Bacillus spp. fermented plant protein mix at two different concentrations of 0.25 and 0.50% (PP-0.25 and PP-0.50, respectively), while the diet prepared with untreated ingredients served as a negative control (PP-0). The daily growth coefficient (DGC) did not differ in the groups fed CNT, PP-0.25, and PP-0.50 diets. The feed conversion ratio (FCR) was low in the CNT and PP-0.50 diets, while (protein efficiency ratio (PER) and apparent protein utilization (APU) were high in the PP-0.50-fed group. The dietary change did not affect survival and whole-body composition, while free amino acids varied among the treatments. Increased nitrogen intake and oxygen consumption were observed in subadults fed with CNT diet. Increasing Bacillus spp. concentrations significantly lowered ammonia-N excretion by 2.09-11.69%. Regression analysis revealed higher coefficients for oxygen consumption ( R 2 = 0.8625 ) and O : N ratio ( R 2 = 0.7791 ), while it was 0.5894 for ammonia-N excretion. The dietary change significantly influenced hemolymph indices and chitinase, glutamate dehydrogenase (GDH), and arginase activity. Results conclude that Bacillus spp. fermented plant protein mix could be a viable fishmeal substitute in shrimp feed.

“…Lipid, as an essential nutrient, contributes to improving growth performance and immunity of aquatic animals (Lin & Shiau, 2003; Mai et al, 1995; Xie et al, 2019). High‐lipid content diets have been increasingly used in aquaculture because of its protein‐sparing effects (Jannathulla et al, 2019; Yigit et al, 2002), which not only reduced nitrogen waste but also decreased feed cost. Nevertheless, a high levels of dietary lipid resulted in anomalous lipid deposition and metabolic disturbance in body, which is frequently accompanied by decreased immunity in fish and shrimp (Jia et al, 2020; Li et al, 2020; Yuan et al, 2016).…”

A 100‐day feeding trial was conducted to investigate the influences of dietary lipid levels on the immunity and mechanism in abalone Haliotis discus hannai Ino. Abalones (initial weight: 10.98 ± 0.05 g) were fed with graded levels of dietary lipid, which were 15.73, 23.41, 31.72, 38.25, 46.35, 55.63, 61.70 and 67.19 g/kg. Results showed that compared with the treatment with 38.25 g/kg of dietary lipid, 67.19 g/kg of dietary lipid increased the cumulative mortality of abalone after a challenge with Vibrio parahaemolyticus. Meanwhile, 67.19 g/kg of dietary lipid decreased the activities of lysozyme (LZ) and acid phosphatase (ACP) in serum, and the mRNA levels of β‐defensin and mytimacin 6 in hepatopancreas of abalone. The mRNA levels of tumour necrosis factor α (tnfα), activator protein 1 (ap‐1), nuclear factor κB (nf‐κb), interleukin 1 receptor‐associated kinase‐4 (irak4), myeloid differentiation primary response protein MyD88 (myd88), toll‐like receptor 2 (tlr2), tlr4 and perilipin‐2, and the protein level of interleukin‐1β (IL‐1β), TNFα, NF‐κBp65, AP‐1, MyD88 and Perilipin‐2 in hepatopancreas were up‐regulated by 67.19 g/kg of dietary lipid. However, the mRNA levels of arginase and inhibitor of κBα (iκbα) were down‐regulated. Besides, 67.19 g/kg of dietary lipid up‐regulated the mRNA levels of executor apoptosis‐related cysteine peptidase 3 (caspase‐3), caspase‐7 and B‐cell lymphoma protein‐2‐associated X protein (bax), and the protein levels of caspase‐3 and c‐Jun N‐terminal kinases (JNK) in hepatopancreas. Moreover, high dietary lipid level down‐regulated the mRNA levels of copper/zinc superoxide dismutase (cuznsod), manganese superoxide dismutase (mnsod), catalase (cat), glutathione peroxidase (gpx), glutathione‐S‐transferase (gst) and NF‐E2‐related factor 2 (nrf2), while up‐regulated the mRNA and protein levels of Kelch‐like ECH‐associated protein 1 (Keap1) in hepatopancreas. It was concluded that a high level (67.19 g/kg) of dietary lipid decreased the immunity of abalone, which might be related to the aggravated inflammation and apoptosis, and decreased anti‐oxidative capacity under Perilipin‐2/TLRs/MyD88/IRAK4/(NF‐κB or AP‐1), JNK/Bcl‐2/Bax and Keap1/Nrf2 signalling.
