“…Wyban et al (1995) Nos ambientes de cultivo, a remoção da amônia pode ocorrer por meio da nitrificação das conversões de amônia para nitrato, realizada pelas bactérias nitrificantes, e de conversões de amônia para biomassa microbiana, realizada pelas bactérias heterotróficas e também pela assimilação fotoautotrófica das microalgas (Ebeling et al 2006). Segundo Hargreaves (1997), quando há pequenas concentrações de amônia no meio, as microalgas são mais eficientes na competição por esta substância do que as bactérias nitrificantes.…”

peso médio inicial de 0,112 ± 0,07g foram cultivados na densidade de 85 camarões m-2 em 6 viveiros escavados (500 m² cada) e revestidos com PEAD (geomembrana). No tratamento com fertilização de carbono não houve renovação da água de cultivo. No tratamento controle os camarões foram cultivados sem adição extra de carbono, e renovação de água foi de 10 % por semana. Não houve diferença significativa entre os parâmetros de qualidade de água (p>0,05). A sobrevivência e conversão alimentar não apresentaram diferenças significativas entre os tratamentos. Entretanto, os camarões cultivados no tratamento com fertilização de carbono apresentaram peso médio final significativamente maior (p<0,05) (10,72 g ± 2,12) em relação ao controle (8,45 g ± 2,03). PALAVRAS CHAVE: Biofloco, Litopenaeus vannamei, fertilização de carbono ABSTRACT Carbon addition in intensive culture of white shrimp Litopenaeus vannamei with bioflocThis study evaluated the effects of carbon addition in the water quality and performance of the white shrimp Litopenaeus vannamei reared in a minimal water exchange intensive system with suspended microbial flocs. Juveniles of L. vannamei with an initial mean weight of 0.112 ± 0.07 g were reared in 6 lined ponds (500 m2) at a density of 85 shrimp/m2. Two treatments with tree replicates each were applied -TM (Molasses treatment) and TC (Control Treatment). Ponds from the Molasses treatment were organically fertilized with molasses (as a carbon source) every week and no water exchange was performed. At the ponds from the control treatment shrimp were reared without molasses addition and water was exchange at a 10 % rate every week. Aeration was provided to all tanks with a 1hp paddle wheel aerators (equivalent to 20hp per hectare). The physical and chemical water quality factors were within the recommended range for this species culture and there were no significant differences between treatments throughout the experimental period. Similarly, survival and feed conversion rate did not show significant differences between treatments (p>0.05). However, shrimp reared in the Molasses treatment achieved significant higher (p<0.05) mean final weight (10.72 ± 2.12 g) than shrimp reared in the control treatment (8.45 ± 2.03 g).

“…This lower temperature tended to decrease the growth potential of the shrimp from its maximum potential (Van Wyk and Scarpa, 1999). Wyban et al (1995) reported that L. vannamei juveniles (3.9 g) showed reduced growth at a temperature of 23 ºC compared with the growth of the same-size class reared at 27 and 28 ºC. The DO 2 concentration showed a slight decreasing trend with the increase in salinity but remained within the recommended range (5.0-9.0 mg/L) for the species.…”

-The objective of this study was to evaluate the effect of salinity on the culture water quality, performance and body composition of Litopenaeus vannamei juveniles (1.16±0.30 g) reared for 36 days in a super-intensive system without water exchange at salinities of 4, 16 and 32‰. Groups of 200 animals (140/m 2 ) were stocked, with three replicates, in nine fiber-cement tanks (1.11 × 1.29 × 0.70 m) with a useful volume of 400 L. Physical and chemical parameters of water, such as temperature and dissolved oxygen before and after midday, pH, alkalinity, total suspended solids, total ammonium nitrogen, nitrite, nitrate, and phosphate, were monitored. Performance parameters like survival, weight gain, specific growth rate, feed conversion ratio and protein retention rate, were also evaluated. The proximate composition of the juveniles was analyzed through the moisture, protein, lipid and ash contents. The physical and chemical parameters of the water were influenced by the treatments. The increased salinity produced a significant increase in the alkalinity and the concentrations of total suspended solids, nitrite and phosphate. Of the parameters that were examined to evaluate the performance and proximate composition of the shrimp, only survival, protein retention rate and body lipid content were significantly influenced. The highest values were found at a salinity of 32‰. However, the analysis of the proximate composition of the bioflocs showed that the moisture, protein and lipid contents increased as the salinity decreased. Growth, use of feed and survival of L. vannamei juveniles reared in a super-intensive system without water exchange is positively influenced by an increase of salinity from 4 to 32‰.

“…However, water temperature ranged from 30.0 to 35.0 and 14.0 to 32.5°C in monsoon and winter seasons, respectively during the experimental period. The low temperature during the winter season might be responsible for low survival and growth of shrimp (Wyban et al, 1995;Yuan et al, 2010) as compared to the survival rate (%), ABW (g) at harvest and FCR of 59, 28.64 and 1.36 during 2008(CIBA, 2008) and 67.74, 26.9 and 1.37 during 2009(CIBA, 2009 respectively in the conventional shrimp ponds. The sizes of the animals in hapa were considerably lesser than the pond reared animals which might be due to more stocking density and confinement.…”

Experiments in hapa and pond were carried out with antibiotic treated tiger shrimp, Penaeus monodon seeds to assess the morphological and hematological parameters during two different seasons viz, monsoon (March to August) and winter (October to February). Survival rates of the antibiotic treated seeds during transport were found to be significantly more compared to untreated control seeds. Average body weight (ABW), feed conversion ratio (FCR) and survival rate after 134 days of culture (DOC) showed no significant difference between antibiotic treated and untreated control seeds during both the seasons. On comparison of seasonal performance, the ABW was 25.79±2.29 g in monsoon and 13.53±2.23 g in winter batch with corresponding FCR of 1.62±0.03 and 2.57±0.01 and survival rate of 55.62±4.94 and 24.62±4.78 per cent respectively with significant difference. Total hemocyte count (THC), granular hemocyte (GH) and nongranular hemocyte (NGH) counts were not statistically significant between antibiotic treated and untreated animals. Significant difference was observed in water and soil quality parameters between seasons but not between antibiotic and control group experimental ponds.
