Studies on the fungal diseases in crustaceans. I. Lagenidum scyllae sp. nov. isolated from cultivated ova and larvae of the mangrove crab (Scylla serrata)

Lagenidium scyllae , a marine mastigomycete from the ova and larvae of the mangrove crab, is described and illustrated as new. The fungus grew at a temperature range of 16-42 C, with an optimum at 22.5-31.8 C. It grew well in peptone-yeast-glucose (PYG) broth containing 2-3% NaCl. In PYG-sea water medium, it grew at a pH range of 5-11.

New species of Berea (Copepoda, Chondracanthidae) parasitic on a flounder from Kuwait

Berea clava, new species, is described based on the specimens recovered from the gill filaments of a flounder, Pseudorhombus arsius (H.-B.), collected in Kuwait Bay of Arabian (Persian) Gulf. This is the second species of Berea.

A new parasitic isopod of the genus Norileca (Crustacea, Cymothoidae) from the Arabian Sea

A new species Norileca borealis belonging to the family Cymothoidae is described in detail and illustrated. The new species is distinguished from the other members of the genus by the details of maxilla 2, maxilliped, pleotelson and pereopod 1.

Copepods of the genus Hermilius (Caligidae) parasitic on marine catfish of Kuwait, with a key to the species of Hermilius

Three species of caligid copepods (Siphonostomatoida) belonging to genus Hermilius Heller, 1865 were recovered from the giant marine catfish, Arius thalassinus Ruppell, taken from the Persian Gulf. They are H. pyriventris Heller, 1865; H. longicaudus n. sp.; and H. longicornis Bassett-Smith, 1898. H helleri Pillai, 1963 is proposed to be relegated to the synonym of H pyriventris. A key to the eight species of Hermilius is provided.

Containing the diseases in aquaculture

A brief discussion is presented on epizootics and their containment in the aquaculture industry, in the form of a question-and-answer interview. Particular reference is made to activities carried out by the OIE (Office International des Epizooties), whose main activities include the provision of guidelines and standards for health protection applicable to international trade in live animals and their products. It has devised an early warning system to apprise its member countries of the occurence of disease outbreaks that would have serious repercussions on public health or the economics of animal products.
