Biological Reviews, 2017 ABSTRACTSedentary broadcast‐spawning marine invertebrates, which release both eggs and sperm into the water for fertilization, are of special interest for sexual selection studies. They provide unique insight into the early stages of the evolutionary succession leading to the often‐intense operation of both pre‐ and post‐mating sexual selection in ...

According to the Hepatosomatic Index and Gonadosomatic Index
Majallah-i ̒Ilmī-i Shīlāt-i Īrān, 1997 The ribbon fishes, belonging to the family Trichiuridae, are one of the most important protein resources in the Indian Ocean. A considerable density of the dominant species of this family, Trichiurus lepturus has been observed in the Oman Sea. During the

Gonadosomatic index (GSI) of female whitefish (Coregonus lavaretus) in Lake Constance
Limnologica, 2000 AbstractFrom 1991 to 1997 the gonadosomatic index (GSI) of pelagic spawning female whitefish (Coregonus lavaretus, local name “Blaufelchen”) in Lake Constance-Obersee was determined. Average GSI increased from low values in summer to a maximum of about 24% immediately before spawning (end of November/beginning of December). The coefficient of variation

Using the gonadosomatic index to estimate the maturity ogive: application to Chilean hake (Merluccius gayi gayi) [PDF]
ICES Journal of Marine Science, 2014 Abstract The proportion of mature fish at age or length is one of the most important population attributes in assessing reproductive potential. This proportion is usually named the maturity ogive. The most crucial step in estimating this proportion deals with maturity staging assessed by macroscopic or histology analysis.
