the objectives of this study were to determine the age, growth, mortality and exploitation of a commercially important fish of northeastern mediterranean sea, mullus barbatus from the karatas coast of iskenderun bay during september 2002 and april 2003. a total of 212 specimens of red mullet were collected by monthly sampling using traditional bottom trawl net by commercial vessel (coskun reis,...

The spotback skate Atlantoraja castelnaui (Arhynchobatidae) is a large and threatened species subjected to fishing pressure, endemic the Southwest Atlantic that occurs from Rio de Janeiro, Brazil, San Jorge Gulf, Argentina. age, growth, age at maturity maximum intrinsic rate of population increase rmax A. were studied using 152 specimens collected off Uruguay north Argentina (35°–42° S), betwee...

Longitudinal data on individual growth and seasonal changes in body mass, girth, blubber thickness are rarely available for cetaceans, making it difficult to assess their population composition nutritional condition. During different time intervals from 1997 2020, we collected longitudinal length, girth,and seventeen harbour porpoises (Phocoena phocoena) human care. We compared Gompertz von Ber...

conclusions the high prevalence of vwd among our patients was the same as other previous reports, suggesting low awareness about this disease and under diagnosis of mild cases. results mean age of our patients was 32.5 ± 10.6 years. the level of von willebrand factor in 22.5% and von willebrand activity in 19.6% of patients was abnormal. the prevalence of vwd among patients with menorrhagia was...

Examining temporal changes in the growth and generation time of fish species can be valuable for understanding population responses to different management measures environmental conditions. Atlantic herring (Clupea harengus) is an ecologically commercially important pelagic forage that occupies southern Gulf St. Lawrence. Here, we developed von Bertalanffy curves estimated yearly values NAFO D...

Determining both the age structure and growth pattern allows to establish causal factors, environmental and/or genetic, that eventually may be responsible for observed of divergence. We examined variation in across populations two toad species, Pelobates cultripes Epidalea calamita exhibit a geographic body size southern Spain. For differed mean but did not correlate with populations. Although ...
