Two-year study of lipophilic marine toxin profile in mussels of the North-central Adriatic Sea: First report of azaspiracids in Mediterranean seafood

Information on stock status is available only for a few of the species forming the catch assemblage of rapido fishery of the North-central Adriatic Sea (Mediterranean Sea). Species that are caught almost exclusively by this gear, either as target (such as Pectinidae) or accessory catches (such as flatfishes apart from the common sole), remain unassessed mainly due to the lack of data and biological information. Based on cluster analysis, the catch assemblage of this fishery was identified and assessed using CMSY model. The results of this data-poor methodology showed that, among the species analyzed, no one is sustainably exploited. The single-species CMSY results were used as input to an extension of the same model, to test the effect of four different harvest control rule (HCR) scenarios on the entire catch assemblage, through 15-years forecasts. The analysis showed that the percentage of the stocks that will reach Bmsy at the end of the projections will depend on the HCR applied. Forecasts showed that a reduction of 20% of fishing effort may permit to most of the target and accessory species of the rapido trawl fishery in the Adriatic Sea to recover to Bmsy levels within 15 years, also providing a slight increase in the expected catches.

We present first data on reproductive biology of male blackspotted smooth-houndMustelus punctulatusin the Adriatic Sea and first histological examination of gonads at different maturation stages and seasonal cycles for this species. We collected samples from 117 male specimens ofM. punctulatusranging in length from 44.6 to 126.5 cm, caught by commercial bottom trawls in the North-Central Adriatic Sea. Microscopic observation revealed a diametric development of testes, in which round-shaped spermatocysts have zonal arrangement, showing seven different stages of development. Males began to mature when they were between 61 and 88 cm body length, which was indicated by the presence of functional claspers or appearance of the spermatogenic cysts. While the smallest mature shark was only 80 cm long, all animals longer than 89 cm were sexually mature. The seasonal analysis of the testes indicated that mature spermatozoa dominated in testes during the first half of the year with a peak in May and June, after which followed less active period during July and August.

Control Region Sequences

AbstractThe North Adriatic Sea is considered a critical feeding and developmental area for Mediterranean loggerhead turtles. In this study, a comparative analysis of mitochondrial DNA control region sequences was carried out on sixty-five loggerhead individuals stranded and caught as bycatch in the Adriatic Sea from 1999 to 2002. We demonstrated the existence of genetic relationships between the North-Central Adriatic (NCA) aggregate and the Central-Eastern Mediterranean rookeries. Short-range and long-range migrations towards the Adriatic Sea were hypothesized by the finding of individuals bearing haplotypes endemic to the nesting populations of Greece and Turkey. The occurrence of individuals belonging to dimensional classes from juveniles to mature adults strongly support both the feeding and developmental role of the NCA.

Pithomyces chartarum (Berk. & Curt.) M. B. Ellis was isolated from bluegrass sod (Poa pratensis L.) in Illinois, Indiana, and Wisconsin during July and August 1986. This is the first report of Pithomyces chartarum in the north central United States and the first report of the fungus in bluegrass sod. The fungus appears to be a saprophyte on senescent bluegrass leaves; its interest as a possible mycotoxin producer is underlined.
