In contrast, for crustacean species, notably penaeid shrimp information is limited (Bureau et al., 2000). Data from crustaceans are difficult to interpret due to wide differences in species, development stages, feed position, feeding rate and estimation of feed consumption then nutrient intake. And because of a lack of data on L. stylirostris some estimates on main parameters collected on different species were necessary to review briefly in order to set a same order of magnitude for each parameters contributing to the energy budget. Sick and Andrew (1972) estimatedHP (HE,HeE+HiE) feeding Macrobrachiumlarvae (7mgav. wt.) tobe on Jmg?1 live weight day?1. Similar data were reported and presented for postlarvae of the same species, since Stephenson and Knight (1980) observed that Macrobrachium postlarvae respired J mg?1 live weight day? values appeared to be high in parison with estimated HE of lobster postlarvae (stages IV and V) at about J postlarvae?1 day?1 (Capuzzo and Lancaster,1979). ButMarsh et al. (2001) measured 3 J larvae?1 day?1 from zoea to megalope (2 wk) stages of Hemigrapsus crassipes. Similarly, F. brasiliensis larvae respired 3 J larvae?1 day?1 (Gaxiola et al., 2002). Heat production (HE) was calculated to be 8–12% above the resting rate (HeE) in P. esculentus (Dall, 1986。 Dall and Smith, 1986).Resting rate of P. vannamei juveniles consumed 21 Jshrimp?1 h?1 reported on a 15day period (Comoglio et al.,2004). Molting (SE) depending directly on water temperature has a determinant effect on metabolism. P. monodon juveniles used 26% accumulated energy for molting。 Read and Caulton (1980) calculated
