Abstract This paper reports on the maturity pattern and the estimation of length at sexual maturity for Aristaeomorpha foliacea females, based on two years of seasonal research trawl surveys. Two approaches were used: gonadic condition (empirical scale) and presence/absence of spermatophores. Ready-to-spawn females (IV stage) occurred almost

Planktonic communities in an anchovy spawning area of the Sicilian Channel: trophic assessment.
2014The trophic structure and related indices were investigated to assess the microplankton functionality in Engraulis encrasicolus (Chordata: Actinopterygii, Clupeiformes) spawning area of the Sicilian Channel. The integrated analysis of trophic parameters and correlated indices (C/N, N/P, POC/LAP+?GLU, POC/Chl-a) highlighted both the heterogeneity and ...

Microbial metabolism and turnover of organic matter in the euphotic layer of Sicilian Channel
2014With the aim of providing an ecosystem approach to fisheries management, the monitoring of biological and environmental information was carried out during two oceanographic cruises (BANSIC 2012-13) performed in the Sicilian Channel in different seasonal conditions. The Sicilian Channel is a spawning area for the Engraulis encrasicolus (Linnaeus, 1758),

The distribution of the red giant shrimp (Aristaeomorpha foliacea) in the Sicilian Channel (Central Mediterranean Sea) is described and geographical differences suggested by the available data set are qualitatively analysed. The unit stock assumption does not seem an unrealistic hypothesis, considering the state of knowledge.

-Males and females of many avian species may show no plumage dimorphism, but often can be sexed by differences in body measurements. Sex determination of many Cory's Shearwaters Calonectris diomedea, was possible by multiplying bill length by bill depth.

Benthic foraminifera are very sensitive to oceanographic parameter variations, to which they rapidly response through changes in the abundance and/or richness of their associations and in morphological variations of their shell. Many studies have used benthic foraminifera as bioindicators. We investigated recent benthic foraminiferal assemblages in the

Sardine pilchardus and anchovy stocks are a commercially important resource for the purse seine fisheries in the South Sicilian continental shelf (Patti et al. 2004). These pelagic species form mono or plurispecific schools during the day for feeding, defense and reproductive advantages and tend to disperse during the night (Pitcher,1993).
