The age of Paracentrotus lividus in the gulf of Tunis was evaluated by analysing the natural growth banding in the interambulacral plates from the oral part of the test. It appeared that growth rates increased in spring and summer, and decreased in autumn and winter. The maximum age and diameter were estimated to be 8 years and 53 mm respectively, Compared to populations of Paracentrotus lividus from NW Mediterranean and Atlantic, that of the gulf of Tunis presented a more rapid growth.

Age, growth and reproductive biology of two endemic demersal bycatch elasmobranchs: Trygonorrhina fasciata and Dentiraja australis (Chondrichthyes: Rhinopristiformes, Rajiformes) from Eastern Australia
Provedor de dados: 103
Autores: Reis,Marcelo; Figueira,Will F.
ABSTRACT Bottom-dwelling elasmobranchs, such as guitarfishes, skates and stingrays are highly susceptible species to bycatch due to the overlap between their distribution and area of fishing operations. Catch data for this group is also often merged in generic categories preventing species-specific assessments. Along the east coast of Australia, the Eastern Fiddler Ray, Trygonorrhina fasciata (Muller &amp; Henle, 1841), and the Sydney Skate, Dentiraja australis (Macleay, 1884), are common components of bycatch yet there is little information about their age, growth and reproductive timing, making impact assessment difficult. In this study the age and growth (from vertebral bands) as well as reproductive parameters of these two species are estimated and...

Idade e crescimento de Lopholatilus villarii Ribeiro no Sudeste do Brasil (Osteichthyes, Malacanthidae)
Provedor de dados: 104

The tilefish, Lopholatihis villarii Ribeiro, 1915 is a commercially-important demersal fish, in the Southeast Brazil, inhabiting calcareous and rocky substrates of the outer shelf and upper continental slope. This study was based on readings of the scale's age rings of 153 especimens, caught from March, 1995 to March, 1996. Scales were found to grow on an isometric proportion with fish length, and age rings are formed betvveen the third and fourth trimesters (winter and spring). The age groups of sampled fish varied from II to X years, and the growth equation in total length (cm) is Lt = I 13.4 [1-e -0.144 (t+ 1.4)] w ith the correspondem one in weight (kg): W, = 22.5[1-e -0.144 (1 + 14)]3 184 obtained from the weight/length regression equation: ln W =...
