Nutrient allocation in the gonads of the sea urchin Arbacia dufresnii in different stages of gonadal development
(Int Science Services/Balaban Publishers, 2014-11-26)
This study reports nutrient allocation in different stages of gonadal development for two populations of the sea urchin Arbacia dufresnii off the Patagonian coast of Argentina (Nuevo Gulf and San Jorge Gulf). The biochemical ...
Reproduction of the sea urchin Tripneustes depressus (Camarodonta: Toxopneustidae) in Bahía de La Paz, Baja California Sur, Mexico
(Universidad de Costa Rica, 2021)
Gonadal Differentiation and Development in the Snouted Treefrog, Scinax fuscovarius (Amphibia, Anura, Hylidae)
(Society for the Study of Amphibians and Reptiles, 2015-09)
Accurate descriptions of gonadogenesis are necessary to have a baseline to detect abnormalities during development and to assess the time a species may be more vulnerable to the action of pesticides, endocrine disruptors, ...
Stages of gonad development during the reproductive cycle of the blackfin snook, Centropomus medius Günther
(Aquaculture Research, 2005)
The reproductive biology of the Blackfin snook Centropomus medius was studied to expand our current knowledge on its aquaculture potential. From April 2001 to November 2002, 301 females and 193 males were captured. A 1:1.6 ...
Nyctiphanes simplex (Crustacea: Euphausiacea) temporal association among embryogenesis and early larval development with female molt and ovary cycles
(Journal of Plankton Reseach, 2012)
Embryogenesis (single cell to twitching stage) and early larval stages (nauplius to calyptopis 3) internal morphology of the sac-spawning species Nyctiphanes simplex was investigated to explore its temporal association ...
Spermatogenesis and gonadal cycle in male Tamoya haplonema and Chiropsalmus quadrumanus (Cnidaria, Cubozoa)
(2019-03-01)
Spermatogenesis has been little studied in cubozoans. This work describes spermatogenesis of two cubozoan species from Brazil, Tamoya haplonema and Chiropsalmus quadrumanus, using light microscopy and histochemical techniques ...
Gonadal development and biochemical composition of female crayfish Cherax quadricarinatus (Decapoda: Parastacidae) in relation to the Gonadosomatic Index at first maturation
(2013-08-15)
Gonadal development of female crayfish Cherax quadricarinatus at first maturation (25.5±3.8 g) was investigated using morphological criteria (Gonadosomatic and Hepatosomatic Indices or GSI and HSI), biochemical composition ...
Effect of dietary protein and lipid levels on gonadal development of female redclaw crayfish Cherax quadricarinatus
(2013-08-14)
The effect of two crude dietary protein (26% and 32% P) and two lipid levels (4.7% and 12% L) on gonadal development of female redclaw crayfish Cherax quadricarinatus was determined. The gonadosomatic index (GSI), hepatosomatic ...
