SPERMATOGENESIS, SPERMATOPHORE, and SEMINAL FLUID PRODUCTION IN THE ADULT BLUE CRAB CALLINESTES DANAE (PORTUNIDAE)
(Crustacean Soc, 2012-03-01)
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) ...

Dry or wet? What is the best choice to determine gonadosomatic and hepatosomatic indexes in females of Macrobrachium amazonicum?
(2019-01-01)
The gonadosomatic (GSI) and hepatosomatic (HSI) indexes are widely used for the evaluation of reproductive biology in crustaceans. However, the use of either wet or dry weight for estimating these indexes is not standardized ...
Comparative liver morphology associated with the hepatosomatic index in five Neotropical anuran species
(Wiley-Blackwell, 2020-10-28)
The liver is an important metabolic organ in vertebrates. In anurans, the hepatosomatic index (HSI) reflects differences in energy storage and reproductive activities between males and females. The objective of this study ...
Effect of intermittent feeding on growth in early juveniles of the crayfish Cherax quadricarinatus
(Elsevier B.V., 2011-09-01)
Three experiments were conducted with juveniles of the crayfish Cherax quadricarinatus to investigate the effect of intermittent feeding regimes on growth and the ability to tolerate the shortage of food. In experiment 1, ...
