Artemia production
The brine shrimp Artemia, especially its nauplii are considered as the best, sometimes the only live food for the larval stages of shrimp and fishes. The main sources of this is from the harvest of natural population inhabiting at GSL, Utah, SFB, California and Chaplin lake, Canada (Sorgeloos, 1975). But the quantum of supply is greatly influenced by the environmental factors of these habits. The short supply of cyst leads to the high price, which in turns affect, the cultivation Of shrimp and fishes. In India itself, the per requirement will be around 10 to 15 tonnes in a couple of years (Royan, 1992). This can be met only by the production of cyst by the culture of Artemia under controlled conditions in hyper saline ponds, which did not have any natural population of Artemia.
The first successful culture of Artemia took place in Maccua , Brazil
in April 1977 (Sorgeloos, 1978) and second in Phillippines with SFB strain (Sorgeloos, 1980) and also in some south East Asian countries like Taiwan, Vietnam etc;. (Vos and Tunsutaparich, 1979, vos and Rosa, 1980, Sahavacharin, 1981). In India,the first successful culture was carried out at the salt pans of Mundra, Gujarat (Royan, 1980) Thanjavur and Marakkanam salt pans (Rahaman, 1990,1993).
In view of this, an attempt was made to study the feasibility of Artemia culture Vietnam strain in the DCW salt works of Sahupuram,TamilNadu for biomass and cysts production which has 1400 acres of salt lands and 140 acres of crystallization ponds.Out of this seven acres have been earmarked for Artemia biomass and cysts production .The dyke construction,and all parameters required for the study have been carefully implemented.
The bore well water has been pumped to maintain required salinity and the depth in the pond. The seven acres of condensation ponds have been divided into 14 ponds and pond no: 2 is further subdivided with additional bands in order to compare the productivity with other ponds.
The salinity has been maintained at 60ppt in the first pond, and saline water is drained by gravitational flow to the other ponds.A few ponds were selected for cysts production in which salinity ranged between 80-120 ppt. Vietnam cysts were inoculated in the ponds for Artemia biomass and cysts production. With regard to the fertilization of the pond water, urea DAP and potash and chicken manure were used. However, bacterial feed was used during nauplii stage. Another bacterial consortium was used during the pre-adult stage. During the adult stage in addition to organic fertilization, bacterial culture were added in the primary pond during pumping of the brine to enable the feed mixed and distributed to all the other thirteen ponds.
In higher salinity cysts was harvested and the biomass production maintained in all ponds at 20-27 millions/pond.
The first batch of 50gms of cysts was harvested during December 2001. Cysts harvest was increased to 1.4kg/day during February,2002.
The cysts were semi processed in the field and later processed with
Fluidized bed dryer.
Cysts were characterized and found to compare favorably with the quality of
Artemia cysts produced
