“…Inclusion of bioflocs in the diet at BFT 75% results in improved growth performances and digestive enzyme activity of the common carp ( Najdegerami et al 2016); also biofloc as a dietary supplement at a 4% level in shrimp feed can enhance the growth and digestive enzyme activities in P. monodon . Bioflocs have been recently projected as a possible novel strategy for disease management with the Bnatural probiotic effect^in contrast to conventional approaches such as antibiotic, antifungal, and external probiotic and prebiotic application (Emerenciano et al 2013a). According to the original definition, probiotics are Borganisms and substances which contribute to intestinal microbial balance^.…”

Biofloc is a conglomeric aggregation of microbial communities such as phytoplankton, bacteria, and living and dead particulate organic matter. Biofloc technology involves manipulation of C/N ratio to convert toxic nitrogenous wastes into the useful microbial protein and helps in improving water quality under a zero water exchange system. It may act as a complete source of nutrition for aquatic organisms, along with some bioactive compounds that will enhance growth, survival, and defense mechanisms, and acts as a novel approach for health management in aquaculture by stimulating innate immune system of animals. Nutritionally, the floc biomass provides a complete source of nutrition as well as various bioactive compounds that are useful for improving the overall welfare indicators of aquatic organisms. Beneficial microbial bacterial floc and its derivative compounds such as organic acids, polyhydroxy acetate and polyhydroxy butyrate, could resist the growth of other pathogens, thus serves as a natural probiotic and immunostimulant. The technology is useful in maintaining optimum water quality parameters under a zero water exchange system, thus prevents eutrophication and effluent discharge into the surrounding environment. Moreover, the technology will be useful to ensure biosecurity, as there is no water exchange except sludge removal. The technology is economically viable, environmentally sustainable, and socially acceptable.

“…A number of broodstock nutrition studies have examined the effect of varying quantities of nutrient classes and/or compounds within such broodstock feeding regimes (Alava et al, 1993, Cahu et al, 1994, Xu et al, 1994a, Marsden et al, 1997, Naessens et al, 1997, Hoa et al, 2009, Emerenciano et al, 2013b, Emerenciano et al, 2013a, Coman et al, 2007a, Chimsung, 2014, Wouters et al, 2001a, Wouters et al, 2001b. Recent studies have suggested that biofloc technology (BFT) may help improve reproductive performance in Penaeid shrimp (Emerenciano et al, 2012, Emerenciano et al, 2013b, Emerenciano et al, 2013c, Braga et al, 2015. In male broodstock, the use of BFT during pre-conditioning allowed the reduction of dietary protein content from 68.4% to 39.9% whilst maintaining spermatophore and sperm quality in pacific white shrimp (Litopenaeus vannamei) (Braga et al, 2015).…”

“…In male broodstock, the use of BFT during pre-conditioning allowed the reduction of dietary protein content from 68.4% to 39.9% whilst maintaining spermatophore and sperm quality in pacific white shrimp (Litopenaeus vannamei) (Braga et al, 2015). When conditioned within BFT systems, female pacific blue shrimp (Litopenaeus stylirostris), pink shrimp (Farfantepenaeus duorarum) and L. vannamei broodstock matured and spawned more frequently and produced a greater numbers of eggs (Emerenciano et al, 2012, Emerenciano et al, 2013b, Emerenciano et al, 2013c. However, the ability to improve reproductive performance in female…”

Improving the Reproductive Performance of Domesticated Giant Tiger Shrimp, Penaeus monodon

The Giant or Black Tiger Shrimp, Penaeus monodon, is an economically significant aquaculture species globally, producing 4.5 million tonnes of product annually at a value of US$ 23.5 billion (FAO, 2016a). Recent innovations in the domestication and selective breeding of P. monodon have resulted in significant improvements in growth rate, survival and pathogen tolerance. However, the reproductive performance of domesticated stocks is inferior compared to that of wild-caught broodstock. Significant reductions in the number of females maturing, egg and nauplii production and hatch rates are commonly reported for domesticated stocks relative to their wild-caught counterparts.The complexities surrounding reduced reproductive performance in domesticated P. monodon are underpinned by two critical issues: 1) a poor understanding of the specific nutritional requirements for reproduction in the species and; 2) a lack of clarity as to the characteristics that define a 'good spawner' -particularly on a biochemical and molecular level. The studies that make up this thesis employed a multidisciplinary approach to assess nutritional, biochemical, and molecular factors that relate to broodstock reproductive performance. Primarily this thesis sought to: (1) investigate whether the current constraints to reproductive performance in domesticated stocks could be overcome by including the microbial biomass derived bioactive Novacq™ (Patent #2008201886) within pelleted diets; (2) evaluate whether current broodstock maturation diets are limiting in relation to repeated spawning and; (3) characterise key interactions between micronutrients and regulatory gene(s) and/or pathways linked to reproduction.A series of reproductive performance trials were undertake to assess the effect of incorporating microbial biomass (Novacq™) within pelleted maturation diets. Preliminary farm-based trials observed significant increases to maturation rate, egg production and nauplii production when domesticated broodstock were fed an experimental pelleted diet containing the Novacq™ ingredient (20% Novacq™ inclusion rate, 2.4% of total diet fed). However, in a subsequent trial conducted under controlled experimental conditions, broodstock fed commercial-grade pelleted diets (30% Novacq™, 5.5% of total diet fed) exhibited a significant decrease in egg hatch rate. Reductions in reproductive performance under controlled experimental conditions were attributed to a decrease in the quality of basal pellet diets, both as a function of increased Novacq™ inclusion and their commercial-based formulation. The above studies suggest the capacity to improve reproductive performance in domesticated P. monodon, using biofloc and its substituents, is highly dependent on the quality of the basal maturation diet fed.ii In response to the aforementioned studies, a trial was undertaken to identify potential factors limiting reproductive performance within current broodstock maturation diets. The effect of repeated spawning on reproductive performance and tissue bioche...
