Growth and survival of pacu Piaractus mesopotamicus (Holmberg, 1887) juveniles reared in ponds or at different initial larviculture periods indoors
(Elsevier B.V., 2003-05-01)
Five-day-old pacu larvae (Piaractus mesopotamicus) with average length and weight of 5.96 mm and 0.42 mg, respectively, were reared as follows: in a semi-intensive system with larvae stocked directly into fertilized ponds ...
LARVICULTURE OF SIAMESE FIGHTING FISH Betta splendens IN LOW-SALINITY WATER
(Inst Pesca, 2017-01-01)
The low-salinity water may improve live food utilization during larviculture, mainly when larvae are fed with salt water organisms. This study aimed to determine the median lethal concentration (LC50) of NaCl in water for ...
Economic evaluation of Piaractus mesopotamicus juvenile production in different rearing systems
(2005-01-03)
In this study, the costs and gross income related to the production of pacu Piaractus mesopotamicus juveniles were evaluated. This evaluation took into consideration a semi-intensive rearing, with direct stocking of the ...
Short periods of food restriction do not affect growth, survival or muscle development on pacu larvae
(Elsevier B.V., 2015-01-20)
The present study evaluated the effects of different fasting periods on survival rate, growth, muscle development and compensatory growth in pacu (Piaractus mesopotamicus) larvae. In Phase I, larvae (5 days post hatching, ...

The effects of four light intensities (0; 2.8 ± 0.9; 5,5 ± 1,8 e 7,8 ± 2,5 1mol s-1 m-2, about 136.5 ± 87.5; 273 ± 43.8 e 390 ± 125 lux, respectively) on survival, productivity, weight gain and larval development of ...
Growth performance and incidence of skeletal anomalies in pacu larvae under different weaning protocolsDesempenho e incidência de anomalias esqueléticas em larvas de pacu sob diferentes protocolos de transição alimentar
(2019-02-03)
The inadequate supply of food during a fish’s larval stage, in addition to impairing growth and survival, may lead to the emergence of skeletal anomalies, since essential nutrients are involved in the osteogenic process. ...
Influência do formato do aquário na sobrevivência e no desenvolvimento de larvas de matrinxã Brycon cephalus (Osteichthyes, Characidae)
(Sociedade Brasileira de Zootecnia, 2006-04-01)
Neste experimento, utilizaram-se cinco aquários cilíndricos com relevo no fundo (em forma de anel) e cinco retangulares com fundo liso para estudo da influência do formato do aquário na sobrevivência e no desenvolvimento ...
Intracohort cannibalism in Dourado (Salminus brasiliensis): Ontogeny, behavior and morphological limitation
(2020-11-15)
The present study assessed the ontogeny and delimitated the morphological boundaries of intracohort cannibalism in dourado (Salminus brasiliensis), a native fish species with potential for aquaculture diversification in ...
