Abstract
The consumer of seafood relates the potential development of animals to the constant use of commercial growth promoters. Nevertheless, nowadays with the development of non antibiotic feed additives, cultured shrimps performance has improved to great level. Present experiment was carriedconducted from 27[sup]th[/sup] May 2009 to 11[sup]th[/sup] October 2009 in shrimp grow out ponds at Diu (U.T) region of Saurashtra coast. The stocking density of tiger shrimp Penaeus monodon Fabricius, 1798 was 7.5 no/m[sup]2 [/sup]in both the culture ponds. Good survival rate (89.70%), average daily growth (0.277), total biomass (2007.48 kg) and less Feed Conversion Ratio (FCR) (1.26:1) were obtained from Kappaphycus alvarezii(Doty) Doty ex P. C. Silva, 1996 sap incorporated in pellet fed shrimps of pond 2, compare to control pond survival rate (73.70%), average daily growth (0.242), total biomass (1476.9) and high FCR(1.52:1) from control pellet fed shrimps of pond 1. There was no significant differences in temperature, pH, dissolved oxygen, turbidity and salinity, whereas micro-nutrients in water parameter vary during lastmonth of culture period. The present investigation concluded that used of K. alvarezii sap to the shrimp feed has enhanced growth in term of survival rate from 73.70% to 89.70%, average daily growth from 0.242 to 0.277 and total biomass weight from 1476.9 kg to 2007.48 kg when compare to control pond shrimps and is economically viable approach in terms of profit. K. alvarezii is rich in micro nutrient, which can boost up the tiger shrimp growth in fewer days of culture.
