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.

Physiological responses of two seaweed biofilter candidates, Gracilariopsis bailiniae Zhang et Xia and Hydropuntia edulis (S Gmelin), to nutrient source and environmental factor
Two gracilarioid species, Gracilariopsis bailiniae and Hydropuntia edulis, were compared based on their growth under different temperature and salinity levels and nitrogen source and on their photosynthetic responses u...
Preliminary research on the anammox process and control of nitrogen compounds in a recirculating aquaculture system
Using anammox process in biological filtration of technological water within recirculating aquaculture system is an alternative to nitrification / denitrification process which can reduce production costs, especially ene...
Feeding ecology of knout goby (Mesogobius batrachocephalus Pallas, 1814) from the Romanian Black Sea (Agigea – Eforie Nord area).
The present study investigates the variations in the feeding ecology of the knout goby (M.batrachocephalus). The index of relative importance indicated opportunistic feeding on macrobenthic fauna. The fish fed mainly on...
The effect of ascorbic acid on hatching performance and tolerance against environmental stressor (high temperature) by immersion of Prussian carp (Carassius gibelio) fertilized eggs
The aim of this study was to evaluate the influence of L-ascorbic acid (AA) in three levels (0,100, 1000 and 2000 mg L-1) on eyed egg and hatching rate, growth and viability of larva, and larval tolerance against high te...
The influence of the anthropic activities on the benthonic macroinvertebrates communities existing in the Jiu and Jiul de Vest rivers, south-west of Romania.
The different sensibility of the benthonic macro-invertebrates has been used in determining the manner in which these communities are being influenced by the alteration of the water quality. The present study aims at fol...
