Size at sexual maturity was studied in Zidona dufresnei through analysis of gonadal tissue samples and secondary sexual characters. Individuals were sampled during two reproductive seasons (austral spring–summer) in the Mar del Plata area, Argentina. Gonadosomatic index was estimated for males and oocyte size frequency was used to estimate the stage of

The size of first maturity of P. cygnus has been estimated using the intersect analysis method and shown to be applicabIe to males as well as females which are smaller than males at this stage of development. The method which is based on significant differences between slopes of regression lines also demonstrated variation in size of maturity of males ...

Fishing regulation methods, first-catch sizes, and sexual maturity of the longarm river prawn Macrobrachium tenellum were estimated through monthly biological and fishery sampling of commercial catches, obtained using the "tapo-bolso" capture system in Mexcaltitán Lagoon and cast nets with 1.0- and 1.5-inch mesh sizes at Camichin Mouth, Nayarit.

Summary Total length (TL) at first sexual maturity was estimated for Atlantoraja castelnaui and Dipturus chilensis from the south-western Atlantic Ocean. Total length at which 50% of the females were captured (50% c) was less than the TL at first sexual maturity (ML) in both species.

A progressive decrease in fish age and size at maturity has been observed in many fish stokc during the last decades, as in Flemish Cap cod (Gadus morhua). Fishing is considered as the main cause in this process because of its size selective capacity and changes that produce in the ecosystem structure.

The gametogenic cycle and number of spawning seasons per year of the female Chlamys (Azumapecten) farreri farreri were investigated by qualitative and quantitative analyses, and also the size at 50% of group sexual maturity (the size of first sexual maturity) was calculated to inform natural living resource management.

Summary The present study describes the length-weight relationships (LWRs), length-length relationships (LLRs), Fulton's condition factor (KF), size at first sexual maturity, spawning season, sex ratio and fecundity of the Morari Aspidoparia morar (Hamilton, 1822) (Cyprinidae).
