Effect of natural production in a zero exchange suspended microbial floc based super-intensive culture system for white shrimp Litopenaeus vannamei
Zero water exchange, super-intensive culture of shrimp in enclosed raceway type systems can be considered environmentally friendly in that containment of water within the system prevents potentialExpand
Importance of biofilm for water quality and nourishment in intensive shrimp culture
Abstract Experiments were conducted to test the usefulness of biofilms—a microbial consortium associated with extracellular polymeric substances attached to submersed surfaces—in reducing the levelsExpand
Effect of practical diets with different protein levels on the performance of Farfantepenaeus paulensis juveniles nursed in a zero exchange suspended microbial flocs intensive system.
Farfantepenaeus paulensis juveniles (72 ± 24 mg), were reared in a suspended microbial flocs system and fed practical diets containing increasing amounts of crude protein (250, 300, 350, 400 and 450Expand
Biofloc technology application as a food source in a limited water exchange nursery system for pink shrimp Farfantepenaeus brasiliensis (Latreille, 1817)
In a 30-day experiment, Farfantepenaeus brasiliensis PL25 (25 � 10 mg;17.9 � 1.6 mm) were raised in nine circular £oating cages with a stocking density of 1000 shrimp m � 3 . Three treatments wereExpand
Effect of calcium hydroxide, carbonate and sodium bicarbonate on water quality and zootechnical performance of shrimp Litopenaeus vannamei reared in bio-flocs technology (BFT) systems
Abstract Litopenaeus vannamei (the Pacific white shrimp) is the most commonly reared species in super-intensive biofloc technology (BFT) without water renewal. In BFT, the pH may decrease due to theExpand
Effects of nitrate toxicity in the Pacific white shrimp, Litopenaeus vannamei, reared with biofloc technology (BFT)
In cultures of the Litopenaeus vannamei with biofloc, the concentrations of nitrate rise during the culture period, which may cause a reduction in growth and mortality of the shrimps. Therefore, theExpand
Superintensive Culture of White Shrimp, Litopenaeus vannamei, in a Biofloc Technology System in Southern Brazil at Different Stocking Densities
The white shrimp, Litopenaeus vannamei, is distributed in the Pacific Ocean from Northern Mexico to the coast of Northern Peru, in waters with temperatures usually above 20 C throughout the year (FAOExpand
Nursery of the pink shrimp Farfantepenaeus paulensis in cages with artificial substrates: Biofilm composition and shrimp performance
Abstract The use of artificial substrates (polyethylene screens) was investigated during the nursery rearing of the pink shrimp Farfantepenaeus paulensis cultured in fixed cages installed in aExpand
Effect of low salinity on microbial floc composition and performance of Litopenaeus vannamei (Boone) juveniles reared in a zero‐water‐exchange super‐intensive system
This study aimed to evaluate the eiect of low salinity on the water quality, microbial £ocs composition and performance of Litopenaeus vannamei juveniles reared over 40 days in a zero-water-exchangeExpand
Substitution of fishmeal with microbial floc meal and soy protein concentrate in diets for the pacific white shrimp Litopenaeus vannamei
Abstract Nutritional values of microbial floc meal and soy protein concentrate were evaluated as alternative protein sources to fishmeal in diets for Litopenaeus vannamei juveniles. A feeding trialExpand
