“…They concluded that the presence of substrates increased the surface area of the tanks and reduced the relative stocking densities; and consequently reduced the stress level of the shrimps, indicated by the higher survival rates. A positive impact of substrates on the production indices for the culture of post-larvae and juvenile shrimp has been reported by several authors [26][27][28]61]. Those authors concluded that the increase in the growth of the shrimp resulted in the reduction in the stocking density because of the presence of substrates.…”

“…The low shrimp performance in intensive cultures has been attributed to the negative social interactions between individuals which may result in an inhibitory effect such as aggressiveness [60] or stimulate cannibalism [29]. Otoshi et al [61] and Zhang [26] suggested that substrates diminish the negative effects of intensification as they provide more space for the shrimp and reduce the stress that can lower their performance.…”

“…Suresh & Lin [63] studied the effect of stocking density on the water quality and production indices of red tilapia in a recirculated water system and reported a negative correlation between stocking density of fish with growth as well as other production parameters. In intensive culture systems, however, the use of shrimp that are genetically selected for fast growth in high densities and the use of formulated feed for such conditions are considered key factors for successful cultivation [61].…”

“…Araneda et al [64] and Otoshi et al [61] suggested that crowding at high densities causes stress on the shrimp, and can compromise performance. Stressed shrimp can be more susceptible to facultative pathogenic microorganisms that are part of their natural microbial flora and aquatic environment [65], which has been noticed in the control tanks of the present experiment.…”

“…This has caused an increase in shrimp culture systems that have adopted artificial substrates to mimic nature in promoting proliferation of natural food sources. One example is the use of leaf litter to promote proliferation of natural biota for maintaining water quality (Bratvold & Browdy 2001, Otoshi et al 2006, Asaduzzaman et al 2008. Hypothetically, if the artificial substrate used is decomposing mangrove leaf litter, the growth and composition of biofilm on the decomposing leaf litter substrate may depend on the extent of exposure to sunlight and sediment.…”

In silvofishery, where shrimp culture is integrated with mangrove trees, the mangrove leaf litter may modify the environment in these culture systems. This study tested the potential of submerged leaf litter of Rhizophora mucronata and associated biofilm in providing a favorable environment for postlarval shrimp Penaeus monodon. Litter decomposition and assembly of microalgae and epifauna were assessed under exposure to sunlight or shade, and presence or absence of sediment. Litter incubated with sediment and exposed to sunlight was rapidly decomposed and supported the highest biomass and diversity of microalgae and epifauna. The litter also supported the highest abundance of diatoms, polychaetes and nematodes during the 4th week of decomposition. Cyanobacteria of the genus Microcystis dominated litter incubated without sediment, in sunlight, after decom position for 5 wk. Under shaded conditions, diatoms of the genus Navicula and the Cyanobacteria Anabaena spp. and Oscillatoria spp. continued to grow at high total ammonium nitrogen, low dissolved oxygen, low temperature and low pH. Our study illustrates synergy between sediment and direct sunlight in promoting diversity of microalgae and polychaetes (of dietary benefit to shrimps), inhibiting growth of Cyanobacteria and maintaining water quality at levels favorable to culture of post- larval shrimp. Our findings support 4 practices for a healthy environment in fish ponds: (1) locating ecological shrimp culture in less forested areas, (2) promoting sediment conditions in artificial shrimp culture systems, (3) exposing litterderived bio film within ponds to sunlight and incubating with sediment to maintain favorable water quality and control Cyanobacteria blooms, and (4) minimizing the use of pond liners and related sludge removal

Effect of biofloc technology (BFT) on the early postlarval stage of pink shrimp Farfantepenaeus paulensis: growth performance, floc composition and salinity stress tolerance

Biofloc rearing media provides a potential food source for shrimp reared in limited or zero water exchange systems. This culture system is environmentally friendly as it is based on limited water use and minimal effluent is released into the surrounding environment. In this study, we evaluated the survival, growth performance and salinity stress tolerance of pink shrimp Farfantepenaeus paulensis postlarvae reared from PL 10 to PL 25 in a biofloc technology limited water exchange system. PL (mean ± SD weight and length of 14 ± 10 mg and 8.10 ± 0.7 mm, respectively) were reared in nine 40-L plastic tanks with a stocking density of 10PL/L. Three culture treatments were applied (1) culture in the presence of bioflocs and commercial feed supply (FLOC ? CF); (2) culture in the presence of biofloc without feed supply (FLOC) and (3) culture in clear water with feed supply (control). Final biomass and survival were significantly higher in FLOC ? CF treatment than the control (P \ 0.05), but did not differ from FLOC. PL reared in the FLOC ? CF treatment achieved a significantly higher final weight, weight gain and length in comparison with the other two treatments (P \ 0.05). No significant difference (P [ 0.05) between treatments was found for salinity tolerance over 24 and 48 h durations. The proximate analysis of floc shown high levels of crude protein (30.4%), but low levels of crude lipids (0.5%). The continuous availability of bioflocs had a significant effect on growth and survival of F. paulensis postlarvae cultured in BFT nursery systems.
