1. Assessment of the nitrification process in a culture of pacific white shrimp, using artificial substrate and bacterial inoculum in a biofloc technology system (BFT)
RESUMO: Litopenaeus vannamei é o camarão marinho mais cultivado em todos os tipos de sistemas, incluindo o Sistema de Tecnologia de Bioflocos (BFT). Os bioflocos são formados por microorganismos, entre estes, bactérias autotróficas que são responsáveis pelo processo de nitrificação. Este estudo teve como objetivo identificar e promover o desenvolvi

2. Replacement of fishmeal for soy protein concentrate in diets for juvenile Litopenaeus vannamei in biofloc-based rearing system
ABSTRACT This study aimed to assess the final body weight, weekly weight gain, yield, apparent feed efficiency, protein efficiency ratio, and feed intake of the Pacific white shrimp (Litopenaeus vannamei) fed four diets containing different levels of soy protein concentrate (SPC) as a replacement for fishmeal, reared in a super-intensive biofloc system. Diet

3. Effect of dietary supplementation with butyrate and probiotic on the survival of Pacific white shrimp after challenge with Vibrio alginolyticus
ABSTRACT This study evaluated the performance, immunology, and survival of the Pacific white shrimp Litopenaeus vannamei to experimental challenge to Vibrio alginolyticus based on the use of the probiotic Lactobacillus plantarum and the combined use of probiotic and butyrate. Four different diets resulted from the addition of additives: butyrate, probiotic,

4. Use of probiotic-supplemented diet on a Pacific white shrimp farm
ABSTRACT The objective of this study was to evaluate the use of a diet supplemented with Lactobacillus plantarum on performance, immunological parameters, and bacterial microbiota of the digestive tract of white leg shrimp (Litopenaeus vannamei). We used six earthen ponds (1.2 ha) stocked with 14 shrimp m−2 (3 g mean weight). Three ponds received a diet su

5. Replacement of fish meal by protein soybean concentrate in practical diets for Pacific white shrimp
ABSTRACTThe objective of this work was to evaluate the performance of Litopenaeus vannameifed different levels (0, 25, 50, 75, and 100%) of soybean protein concentrate (63.07% crude protein, CP) to replace fish meal-by product (61.24% CP). The study was conducted in clear water in fifteen 800 L tanks equipped with aeration systems, constant heating (29 ºC),

6. Evaluation of jumbo squid (Dosidicus gigas) byproduct hydrolysates obtained by acid-enzymatic hydrolysis and by autohydrolysis in practical diets for Pacific white shrimp (Litopenaeus vannamei)
The marine bioprocessing industry offers great potential to utilize byproducts for fish meal replacement in aquafeeds. Jumbo squid is an important fishery commodity in Mexico, but only the mantle is marketed. Head, fins, guts and tentacles are discarded in spite of being protein-rich byproducts. This study evaluated the use of two jumbo squid byproduct hydro

7. Effect of salinity on performance and body composition of Pacific white shrimp juveniles reared in a super-intensive system
The objective of this study was to evaluate the effect of salinity on the culture water quality, performance and body composition of Litopenaeus vannamei juveniles (1.16±0.30 g) reared for 36 days in a super-intensive system without water exchange at salinities of 4, 16 and 32‰. Groups of 200 animals (140/m2) were stocked, with three replicates, in nine f

8. Efeito da radiação gama na reatividade alergênica e nas propriedades físico-químicas e sensoriais de camarão (Litopenaeus vannamei) / Effect of gamma radiation on the allergenic reactivity and the physicochemical properties and sensory shrimp (Litopenaeus vannamei)
A hipersensibilidade a alimentos é comum em crianças e adultos. O camarão, apesar de muito apreciado, é um alimento potencialmente capaz de desencadear reações alérgicas em indivíduos geneticamente predispostos. O principal alérgeno em camarão é a tropomiosina. O objetivo desse experimento foi avaliar os efeitos da radiação gama na reatividade I

9. Artificial family selection based on growth rate in cultivated lines of Litopenaeus vannamei (Decapoda, Penaeidae) from Venezuela
We investigated the effects of family selection on the growth rates of four genetic lines of Litopenaeus vannamei, the Pacific white shrimp, from Venezuela. The mean family weight at selection was 16.79 g and the mean growth rate was 0.169 g d-1 at a mean age of 138 days. The mean growth rates per generation were 0.141 g d-1 for the parental generation (P0),

10. The experiences and the resistance of the native population of Cumbe in the conflicting cultural scenario of subsistence fishery and shrimp farming, and of the carcinicultura, Cumbe, Aracati-CE / O trabalho no mangue nas tramas do (des)envolvimento e da des(ilusÃo) com "esse furacÃo chamado carcinicultura": conflito socioambiental no Cumbe-Aracati-CE
Shrimp farming is the main cause of the rapid growth observed in aquiculture around the world. The practice was introduced in Brazil in the 1970s, but it required appropriate farming technology based on the Pacific white shrimp (Litopenaeus vannamei), incentive through public policies and funding by state banks beginning in 1996/1997 to trigger the boom whic

11. Fluorescent amplified fragment length polymorphism (fAFLP) analyses and genetic diversity in Litopenaeus vannamei (Penaeidae)
The Pacific white shrimp, Litopenaeus vannamei (Penaeidae), represents about 95% of all Brazilian shrimp production. The Brazilian L. vannamei foundation broodstock was made up of specimens collected from different American Pacific sites, but little information was collected on the genetic structure of the broodstock. We used the fluorescence amplified fragm
