Effect of Water Exchange and Mechanical Aeration on Grow-out of the Amazon River Prawn in Ponds
(Journal of the World Aquaculture Society, 2013-12-01) [Artigo]
Exchange and aeration of pond water are common practices in semi-intensive freshwater prawn culture, but there is lack of scientifically based information on the results. We evaluated the effects of water flow through the ...
SPERMATOGENESIS, SPERMATOPHORE, and SEMINAL FLUID PRODUCTION IN THE ADULT BLUE CRAB CALLINESTES DANAE (PORTUNIDAE)
(Journal of Crustacean Biology, 2012-03-01) [Artigo]
Sperm and spermatophore production in Callinectes danae Smith, 1869 were examined by histochemistry and correlated with gonadosomatic (GSI) and hepatosomatic (HSI) indices. The GSI from developing (DE) and mature (MAT) ...
Effect of salinity on the metabolism and osmoregulation of selected ontogenetic stages of an Amazon population of Macrobrachium amazonicum shrimp (Decapoda, Palaemonidae)
(Brazilian Journal of Biology = Revista Brasleira de Biologia, 2015) [Artigo]
Probably as a function of their wide geographical distribution, the different population of Macrobrachium amazonicum shrimp may present distinct physiological, biochemical, reproductive, behavioral, and ecological patterns. ...
Reproductive migration and population dynamics of the blue crab Callinectes danae in an estuary in southeastern Brazil
(Marine Biology Research, 2012-01-01) [Artigo]
Portunid crabs are an important resource in estuaries, and require appropriate management to guarantee their long-term availability. We investigated the population dynamics and reproduction of Callinectes danae in the ...
Effect of polyunsaturated fatty acids on the fecundity of the Amazon river prawn Macrobrachium amazonicum (Heller, 1862)
(Aquaculture Research, 2012-11-01) [Artigo]
Effects of the ratio of dietary fatty acids, namely n-3 (mainly long chain polyunsaturated LC-PUFA) to n-6 PUFA on the fecundity of Macrobrachium amazonicum were evaluated. In T1, the diet had equal and low levels of dietary ...
Male reproductive system of the red brocade hermit crab Dardanus insignis (Diogenidae) and its relationship to other family members
(Zoomorphology, 2014-06-01) [Artigo]
The reproductive system of hermit crabs shows species-specific morphology, which can be used in phylogenetic analysis. Here, we describe the male reproductive system of the hermit crab Dardanus insignis, including morphological ...
