Algal blooms of spp. and Paralytic Shellfish Poisoning toxicity events in mussels farmed in Sicily.

Marine biotoxins can accumulate in filter- feeders bivalve molluscs, that may represent a source of potential health problems being vectors of toxins, that are transferred to humans through their consumption. Harmful Algal Blooms impact on aquaculture may give also economic losses due to temporary closures of contaminated shellfish harvest and marketing. The presence of toxic algae for Paralytic Shellfish Poisoning (PSP), with recurrent toxic blooms of dinoflagellates, such as several species, been known since 2000 in the waters of an Ionian bay of Sicily, the Syracuse harbour, where shellfish farms are located.

The Influence of Acute Handling Stress on Some Blood Parameters in Cultured Sea Bream ( Linnaeus, 1758).

The effect of acute handling stress on haematological profile, blood glucose and lactate (secondary stress markers) in cultured sea bream was evaluated. Sixty six were used and equally divided into two groups (A and B). Group A was not subjected to stress, Group B was subjected to acute handling stress.
