“…2000 mg/L did not affect growth or yield of fingerling or juvenile tilapia (Perez-Fuentes et al, 2016;da Silva et al, 2018). However, 400-500 mg/L TSS appears to be a common target concentration for tilapia (Azim and Little, 2008;Long et al, 2015;Liu et al, 2018aLiu et al, , 2018b.…”

Given tilapia grown in the biofloc technology production system can consume the biofloc, it should be possible to optimize formulated diet protein content to account for nutrition derived from consuming biofloc. The present study, conducted in an outdoor biofloc technology production system, evaluated impacts on fish production indices, common microbial off-flavors, and water quality dynamics for hybrid tilapia (Oreochromis aureus × O. niloticus) fed diets formulated to contain 22.5%, 27.7%, and 32.3% digestible protein (DP) and 6% lipid. Fingerlings (32.2 ± 10.1 g/fish) were stocked in tanks (18.6 m 2 ; 16.6 m 3) in May 2016 at 25/m 2 (29/m 3) and grown for 5 months to market size. At harvest, fish fed the 22.5% DP diet were significantly smaller (518 g/fish) and had significantly higher feed conversion (1.5) than those fed the higher DP diets (553-564 g/fish and 1.4, respectively). Feed nitrogen input and nitrification rate increased linearly with increased DP. Results of this study suggest that by using ideal protein theory to formulate diets supplemented with the first four limiting amino acids (Lys, Met, Thr, Ile) digestible protein can be reduced from 32.3% to 27.7% without adversely affecting hybrid tilapia productivity indices. Market size distributions, nutrient retention, 2-methylisoborneol and geosmin off-flavors, and pond water quality dynamics in relation to diet DP also are discussed.

“…The high demand for aquaculture products entails intensified aquaculture activities, which not only require a certain degree of technical skill and knowledge but also negatively affects production quality. High stocking density (crowding) is known to decrease body size, specific growth rate, feed conversion ratio, immune response and survival of various aquaculture fish (Abdel-Tawwab et al 2014;Liu et al 2018;Maucieri et al 2019;Wang et al 2019b) and crustacean species (Li et al 2006;Sun et al 2016;Liu et al 2017). This is because, in addition to high contact ratio and transmission rate, high stocking density induces a chronic stress response, which subsequently leads to the elevation of metabolic rate (Lupatsch et al 2010;Balasch & Tort 2019).…”

Protein-protein interactions (PPIs) play integral roles in a wide range of biological processes that regulate the overall growth, development, physiology and disease in living organisms. With the advancement of high-throughput sequencing technologies, increasing numbers of PPI networks are being predicted and annotated, and these contribute greatly towards the understanding of pathogenesis and the discovery of novel drug targets for the treatment of diseases. The use of this tool is gaining popularity in the identification, understanding and treatment of diseases in humans and plants. Due to the importance of aquaculture in tackling the global food crisis by producing cheap and high-quality protein source, the maintenance of the overall health status of aquaculture species is essential. With the increasing omics data on aquaculture species, the PPI network is an emerging tool for fish health maintenance. In this review, we first introduce the concept of PPI network, how they are discovered and their general application. Then, the current status of aquaculture and disease in aquaculture are discussed. The different applications of PPI network in aquaculture fish disease management such as biomarker identification, mechanism prediction, understanding of host-pathogen interaction, understanding of pathogen co-infection interaction, and potential development of vaccines and treatments are subsequently highlighted. It is hoped that this emerging tool-PPI networkwould deepen our understanding of the pathogenesis of various diseases and hasten the prevention and treatment processes in aquaculture species.

“…Thus, raising the stocking density is considered to be a feasible approach for improving the annual production of M. japonicus. Nevertheless, an increasing stocking density can lead to crowding stress that adversely affects the growth, feed efficiency, metabolism and immune function of cultivated animals, resulting in greater production costs and poor yield (Aksakal et al, 2011;Arnold, Sellars, Crocos, & Coman, 2006a;Bolasina, Tagawa, Yamashita, & Tanaka, 2006;Coman, Arnold, Jones, & Preston, 2007;Duy et al, 2012;Lin et al, 2015;Liu, Jia, Han, Huang, & Lei, 2016;Liu et al, 2018Liu et al, , 2019Liu, Zhu, Liu, Guo, & Ye, 2017;Montero, Izquierdo, Tort, Robaina, & Vergara, 1999;Rahman et al, 2005;Refaey et al, 2018;Tolussi, Hilsdorf, Caneppele, & Moreira, 2010). Furthermore, M. japonicus shows increased cannibalism characteristics, which will heavily decrease the survival rate at high stocking density (Tom & Lewinsohn, 1983;Wu et al, 2001).…”

Stocking density is a biotic factor affecting the production of cultivated animals in aquaculture. Herein, a rearing trial was conducted to investigate the impact of stocking density on the survival, growth performance and physical injury of Marsupenaeus japonicus juveniles in a flowing water aquaculture system. Five stocking densities were examined in this study, that is, 10, 20, 40, 80 and 160 individuals/m2. Throughout the experiment, ammonia nitrogen and nitrite concentrations ranged from 0.02 ± 0.006 mg/L to 0.08 ± 0.035 mg/L and 0.002 ± 0.001 mg/L to 0.076 ± 0.021 mg/L respectively. The survival rate, specific growth rate (SGR), weight gain (WG), absolute growth rate (AGR) and coefficient of variation for weight (CV) across the stocking densities ranged from 90.38 ± 3.20% to 94.33 ± 4.73%, 1.42 ± 0.16%/day to 1.53 ± 0.05%/day, 1.09 ± 0.19 g to 1.15 ± 0.16 g, 0.018 ± 0.003 g/day to 0.019 ± 0.004 g/day and 16.21 ± 5.78% to 35.09 ± 10.68% respectively. Within the investigated densities, the survival rate and the abovementioned growth parameters were not significantly (p > .05) affected by the stocking density, consequently, a higher stocking density resulted in a significantly (p < .05) greater final biomass. The results regarding physical injury showed that the antennal breakage rate displayed a tendency of a positive correlation with the stocking density. Overall, the current study provides basic data for establishing a viable intensive farming system for M. japonicus and a promising indicator for easily assessing the crowding stress status of M. japonicus.
