The objective of this study was to document the immunological effects of growing shrimp in biofloc systems. The experiment consisted of four types of biofloc systems in which bioflocs were produced by daily supplementation of four different carbon sources, i.e. molasses, tapioca, tapioca-by-product, and rice bran, at an estimated C/N ratio of 15 and a control system without any organic carbon a...

Biofloc systems were developed to improve environmental control over production. In places where water is scarce or land is expensive, more intensive forms of aquaculture must be practiced for cost-effective production. There are strong economic incentives for an aquaculture business to be more efficient with production inputs, especially the most costly (feed) and most limiting (water or land)...

Problem Statement: The activated sludge system needs to improve the operational performance and to achieve more effective control. To realize this, a better quantitative understanding of the biofloc characteristics is required. The objectives of this study were to: (i) Study the biofloc characteristics from kinetics-mass transfer interaction point of view by quantification of the weight of the ...

the study was conducted to evaluate the effect of different levels of synthetic lysine (slys) on dry matter intake (dmi), average daily weight gain (adg), dry matter conversion ratio (dmcr), carcass characteristics and economics of productionof finisher broiler chicks. as 240 day-old broiler chicks were randomly distributed to 12 pens of 20 chicks each and assigned to four treatment rations in ...

ABSTRAKBakteri membentuk bioflok, menghasilkan protein mikroba dan memungkinkan untuk mendaur ulang pakan yang tidak terpakai. Flok terdiri atas organisme seperti bakteri, plankton, jamur, alga, partikel tersuspensi mempengaruhi struktur nutrisinya. Pembentukan bioflok bertujuan meningkatkan pemanfaatan nutrien, menghindari stres lingkungan predasi. Akuaponik merupakan kombinasi sistem akuakult...

Success of the shrimp aquaculture industry requires technological advances that increase production and environmental sustainability. Indoor, superintensive, aquaculture systems are being developed that permit year-round production of farmed shrimp at high densities. These systems are intended to overcome problems of disease susceptibility and of water quality issues from waste products, by ope...

Biofloc technique is a method of fish culture using minimal water exchange and microbial aggregates formed within the media as supplementary feed. protein source currently not being considered part feeding dosage in catfish culture. This present work aimed to determine effects commercial feed reduction on growth performance, quality, hematology cultured biofloc ponds. Fish with an average body ...

Biofloc systems in Pacific white shrimp (Penaeus vannamei) culture generate floccules that remove wastes, and hence, biofloc formation is promoted for production. This study evaluated the induction of using microalgae probiotic bacteria hyper-intensive culture. The experiment was performed six weeks tanks (28,000 L each) stocked 350 ind m-3 weight 1400 ± 30 mg. Three treatments were assessed: 1...
