“…Highest SGR were observed in the T10 and lowest in T40. Similar observation was done by Araneda et al, (2008), Williams et al, (1996) and Sookying et al, (2011), who reported that that increasing density and shrimp biomass had negative effect on growth.…”

“…This pattern is consistent with the theory of density dependence, which states that competition for essential resources can induce density-dependent mortality to lower a population's size (Keeley 2001). Although no previous studies have examined competition between wild and captive-bred penaeids, densitydependent survival in response to food limitation has been observed in P. esculentus and P. setiferus (Williams et al 1996, Arnold et al 2005. Since epiphytes contribute significantly to the juvenile penaeid diet (Kitting et al 1984, Dall et al 1990b, competition for the epiphytes present in our competition for food experiment may have led to higher mortality rates in both wild and captive-bred juveniles when densities were increased.…”

The mechanisms that drive density dependence are rarely studied in the applied context of population management. We examined the potential for competition for food and shelter and the resulting demographic density dependence to influence how well populations of the eastern king prawn Penaeus plebejus Hess can recover following marine stock enhancement programmes in which captive-bred juveniles are released into the wild. Specifically, manipulative laboratory experiments were used to quantify the differential effects of competition for food and competition for shelter on survival of wild and captive-bred P. plebejus as densities were increased and as each category of P. plebejus (wild or captive-bred) was supplemented with the alternate category. Increasing population densities when food and shelter were limited lowered survival for both categories. When food was limited, survival of both categories was unaffected by addition of the alternative category. Adding wild P. plebejus to their captive-bred counterparts when shelter was limited under laboratory conditions resulted in significantly higher mortality in captive-bred individuals. In contrast, adding captive-bred P. plebejus to wild individuals under these conditions did not affect wild P. plebejus. We conclude that if the current results can be extended to wild conditions, competition for shelter may lead to the loss of captive-bred P. plebejus, thereby reducing the intended outcomes of stock enhancement. This highlights the importance of investigating interactions between wild and captive-bred animals prior to stock enhancement to predict long-term outcomes and identify situations where stock enhancement could be an effective response to the loss of populations or recruitment limitation.

“…The decrease in stocking density because of mortalities promoted the growth of the shrimp that survived in tanks, and several authors have reported an inverse relationship between stocking densities and the performance of shrimp (Krummenauer et al 2011;Moss and Moss 2004;Otoshi et al 2007;Williams et al 1996).…”

The use of different aerators on Litopenaeus vannamei biofloc culture system: effects on water quality, shrimp growth and biofloc composition

This study evaluated the effects of different aeration types on water quality, shrimp growth and biofloc composition in a Litopenaeus vannamei culture. The study was conducted with three treatments: (1) PR-propeller aspirator pump aerator; (2) VP-vertical pump aerator; and (3) BL-diffused air blower. The study was performed in a greenhouse with nine 35,000-L rectangular tanks. Water quality parameters (temperature, salinity, dissolved oxygen, pH, ammonia, nitrite, nitrate, settleable and suspended solids) were measured along the 33 experimental days. Moreover, samples were collected to quantify the microorganisms present in the tanks. At the end of the study, samples of the biofloc of each tank were collected to proximal analysis. Throughout the experiment, the temperature, pH, salinity and alkalinity were maintained within the recommended levels for L. vannamei. The propeller treatment showed a concentration of total ammonia above the recommended levels and lower densities of ciliates and flagellates, most likely because of inadequate biofloc formation in this treatment. The final weight was higher in the blower and propeller treatments. However, survival was lower in the propeller treatment compared to the other treatments. The results of this study suggest that diffused air systems (air blower) improve the formation of biofloc and growth performance of L. vannamei.
