Abstract |
The industrial farming of penaeid shrimps began in Italy in the early eighties with the introduction of Penaeus japonicus , that replaced Penaeus kerathurus . In Italy there are no farms for producing eggs and fry on a commercial basis, the restocking material is usually imported from abroad at the stage of post-larval 22-25. Various pathologies were found that appeared to be connected with husbandry techniques, such as overfeeding with low water exchange, overcrowding and poor water quality. Our laboratory diagnosed diseases caused by: virus: infectious pancreatic necrosis (IPN) virus was isolated on EPC-RTG2 cells from spawners without apparent mortality; bacteria: the most frequently isolated bacterium was Vibrio anguillarum , on TSA, marine agar and TCBS; parasites: serious infections of the gills were seen caused by zootamnium; fungi: very few infections by Fusarium solani , causing lesions in the eye, were diagnosed. |
