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.

Journal of Fish Biology, EarlyView.Abstract The European pilchard, Sardina pilchardus, is a key small pelagic fish sustaining Mediterranean ecosystems and fisheries. This study represents the first comprehensive biological and population dynamics assessment of the European pilchard by applying the length‐based spawning potential ratio (LB‐SPR) approach to S.

Journal of Fish Biology, EarlyView.Abstract Alternative male morphs are found in many species of fishes. These morphs often differ in suites of social behaviours, such as aggression and territoriality, associated with alternative reproductive tactics. Such consistent morph‐typical behavioural profiles suggest common differences in underlying neuroendocrine mechanisms.

Efficiency of letrozole loaded PLGA nanoparticles on sex reversal of Poecilia reticulata (Peters, 1859) [PDF]
, 2015 Males of Poecilia reticulata showed extreme diversity in color, particularly of their fins, while the females lack the bright colors and are largely whitish. Such extreme variability of color and finnage lead to demand of males in the markets. The aim of

Journal of Fish Biology, EarlyView.Abstract Anadromous Arctic char (Salvelinus alpinus) and northern form Dolly Varden (Salvelinus malma malma) are highly valued by Indigenous communities in northern Canada. Rapid, ongoing environmental changes are affecting populations of both of these iteroparous species, and understanding variability in life‐history tactics is essential for ...
