Description:
Shrimp hatcheries around the world continue to be heavily dependent of
wild brood stock. This is a common threat for shrimp hatcheries in major shrimp
farming countries. This dependence is inherently unstable and potentially
dangerous, as the number of wild shrimp stocks around the world are tested to be
positive for variety of dangerous infections increases (such as viruses). As the
shrimp aquaculture industry has developed, the number of farms relying on seed
hatcheries has increased too. On the other hand hatcheries are adopting technology
to control the reproductiove process and produce ganeration after generation of
shrimp without totally relying of wild populations.
At present. There are hatcheries in khouzestan province, Abadan region.
Which only 6 of them are active with production of 20 Milion postlarvae each
hatchery. (of course hatchery in Bandar- e- Imam was onl active in 1380).
The aim of our research project is to determine, the hatchery management, the
fungal. Bacteria and parasite flora of shrimp larvae, water supply, water physico
chemical factors and suitable use of dose chemicals. This study has been
conducted since Farvardin1380 to Aban 1381 in Abadan hatcheries and in 1380 in
Bandar-e- Imam.
In this study, 7 genus and species bacteria such as, V.alginolyticus, V.
splendidus, V. vulnificus, staphylococcous and A. hydrophila were diagnosed.
Also, 10 genus and species fungi, trichothesium, Aspergilus, A. niger,
cladosporium, mucor, fosarium, penicelium, Rhizopus and yeast were isolated.
Among the received larve, zoothaminum and vorticella protozoa wer observed in
Abadan hatchery.
Water physico chemical Factors was terlatively normal, but heavy metal
highly observed.
