  • Effects of intensification of the amazon river prawn, macrobrachium amazonicum, grow-out on effluent quality
    Janaina Mitsue Kimpara, Patricia Moraes-Valenti, Julio F. Queiroz, Michael Bernard New
    Journal of the World Aquaculture Society, 2013
    Studies to determine suitable levels of intensification are essential for developing sustainable aquaculture. The objective of this study was to evaluate the quality of effluents discharged from ponds stocked with 10 (D10), 20 (D20), 40 (D40), and 80 (D80) postlarvae of Macrobrachium amazonicum/m 2 . Intake and effluent water samples were taken throughout a 5.5-mo grow-out cycle. In that study, twelve 0.01-ha earthen ponds were stocked postlarvae with 0.01g. Average water exchange rate was 15%/d; water was discharged from the bottom of the ponds. Prawns were fed a commercial feed with 38% crude protein according to their biomass (3‐10%) and the concentration of dissolved oxygen (DO). In our research, temperature, turbidity, total suspended solids, conductivity, DO, pH, biochemical oxygen demand (BOD), chemical oxygen demand (COD), N-ammonia, N-nitrite, N-nitrate, N-Kjeldahl nitrogen, total phosphorus, and soluble orthophosphate were measured every 15d throughout the experiment in the early morning (0630 to 0730h). Turbidity was lower in D10 than in D20 and D40 and total phosphorus was higher in D80 than in D10 and D20. An analysis of principal components comparing treatments and intake water showed three groups: intake, D10 and a cluster of D20, D40, and D80. On the basis of the water characteristics found in our study it appears that the farming of M. amazonicum is likely to have a low environmental impact, at least up to a stocking density of 80prawns/m 2 . The increasing demand for aquatic animal products has led world aquaculture to the intensification of production systems and to the diversification of cultured species. The intensification normally means an increase in stocking density, and consequently an increase
  • Efficiency of bioaugmentation in the removal of organic matter in aquaculture systems
    RB Lopes, RA. Olinda, BAI Souza, JEP Cyrino, CTS Dias, et al.
    Brazilian Journal of Biology, 2011
    Several techniques are currently used to treat effluents. Bioaugmentation is a new bioremediation strategy and has been employed to improve effluent quality by treating the water during the production process. This technology consists basically of the addition of microorganisms able to degrade or remove polluting compounds, especially organic matter and nutrients. The objective of this study was to assess the effects of bioaugmentation on some parameters of organic matter and on the performance of juvenile tilapias in an intensive aquaculture production system. The combination of two bacterial consortiums in a complete randomized design was employed in a factorial analysis with two factors. Statistical differences between treatments were analyzed by the analysis of variance (ANOVA) and Tukey test at the 5% level. One of the treatments, heterotrophic bacterial supplementation, was able to reduce biochemical oxygen demand (BOD) by 23%, dissolved organic carbon (DOC) by 83.7% and phytoplanktonic biomass by 43%. On the other hand, no damage was done to either the physical-chemical indicators of water quality or to the growth performance of juvenile tilapias assessed in this study.

    Aquaculture ponds sequester about 16.6MTyr(-1) of organic carbon worldwide representing around 0.21% of annual, global carbon emissions.
  • Emergy assessment of integrated production systems of grains, pig and fish in small farms in the South Brazil
    Otávio Cavalett, Júlio Ferraz de Queiroz, Enrique Ortega
    Ecological Modelling, 2006
    The present study uses emergy methodology to evaluate environmental aspects of integrated production systems of grains, pig and fish in small farms in the South region of Brazil. New emergy parameters that use partial renewability factor of each input were used to improve emergy accounting. These parameters were already applied to different case studies and are very appropriate for use in emergy assessment of integrated agricultural systems. The following indicators were calculated for the integrated production system of grains, pig and fish: transformity: 948,000 sej/J; renewability: 24%; emergy yield ratio: 1.44; emergy investment ratio: 2.28; environmental loading ratio: 3.13 and emergy exchange ratio: 6.8. These values were compared with results calculated for grains, pig and fish production subsystems working in a separated way. The results obtained signalize that an integrated system has better emergy efficiency, is more sustainable and is less stressful on the environment in comparison with separated production subsystems. The emergy indicators presented are discussed in the text and they will be useful in further work to assist the formulation of public policy, and also to recommend better management practices to farmers.
  • Feasibility of Retention Structures, Settling Basins, and Best Management Practices in Effluent Regulation for Alabama Channel Catfish Farming
    Claude E. Boyd, Julio F. Queiroz
    Reviews in Fisheries Science, 2001
    The United States Environmental Protection Agency has initiated rule making for aquaculture effluents. The contents of the rule will not be finalized until June 2004, but effluent containment in retention structures, effluent treatment in settling basins, and best management practices have been components of rules for other animal production facilities. The main aquaculture activity in Alabama is pond culture of channel catfish (Ictalurus punctatus). Fish are harvested with seines, and it is not necessary to drain ponds more than once in 5 to 10 years. Thus, effluents result mainly from storm overflow in winter and early spring. Catfish ponds in Alabama cannot be operated without effluent. A retention structure of enormous size would be necessary to retain storm overflow without discharge. Treatment of storm overflow by sedimentation also is not feasible. Settling basins with enough volume to provide a hydraulic retention time of 8 h would often be larger than production areas. Most catfish farms in Alabama are built to property lines or streams, and there would seldom be enough space available for settling basins to treat draining effluent. The best approach to effluent management in Alabama catfish farming appears to be the development and implementation of best management practices (BMPS) to reduce the volume and improve the quality of effluents. Considerable research has been conducted on water quality in catfish production ponds, and there is a large database to use in forming BMPs. Several categories of BMPs are provided for consideration as follows: BMPs to reduce effluent volume; BMPs to minimize suspended solids through erosion control; BMPs to improve pond water and effluent quality; BMPs for use of therapeutic agents and other chemicals; BMPs for siting and construction of new ponds or farms. Suggestions on how a formal system of BMPs could be prepared for Alabama catfish farming are given.
  • Environmental assessment of channel catfish Ictalurus punctatus farming in Alabama
    Claude E. Boyd, Julio Queiroz, Jeongyeol Lee, Martha Rowan, Gregory N. Whitis, et al.
    Journal of the World Aquaculture Society, 2000
    An environmental assessment was made of Alabama channel catfish Ictalurus punctahrs farming which is concentrated in the west-central region of the state. There are about 10,OOO ha of production ponds with 10.7% of the area for fry and fingerlings and 89.3% for food fish. Food fish production was about 40,800 tons in 1997. Watershed ponds filled by rainfall and runoff make up 76% of total pond area. Water levels in many of these ponds are maintained in dry weather with well water. The other ponds are embankment ponds supplied by well water. Harvest is primarily by seine-through procedures and ponds are not drained frequently. The main points related to Alabama catfish farming and environment issues are as follows: 1) catfish farming in Alabama is conservative of water, and excluding storm overflow, about two pond volumes are intentionally discharged from each pond in 15 yr; 2) overflow from ponds following rains occurs mostly in winter and early spring when pond water quality is good and stream discharge volume is high; 3) total suspended solids concentrations in pond effluents were high, and the main sources of total suspended solids were erosion of embankments, pond bottoms, and discharge ditches; 4) concentrations of nitrogen and phosphorus in effluents were not high, but annual effluent loads of these two nutrients were greater than for typical row crops in Alabama; 5) ground water use by the industry is about 86,000 m3/d, but seepage from ponds returns water to aquifers; 6) there is little use of medicated feeds; 7) copper sulfate is used to control blue-green algae and off-flavor in ponds, but copper is rapidly lost from pond water; 8) although sodium chloride is applied to ponds to control nitrite toxicity, stream or ground water salinization has not resulted from this practice; 9) fertilizers are applied two or three times annually to fry and fingerling ponds and occasionally to grow-out ponds; 10) hydrated lime is applied occasionally at 50 to 100 kgha but this does not cause high pH in pond waters or effluents; 11) accumulated sediment removed from pond bottoms is used to repair embankments and not discarded outside ponds; 12) sampling above and below catfish pond outfalls on eight streams revealed few differences in stream water quality; 13) electricity used for pumping water and mechanical aeration is only 0.90 kWWkg of production; 14) each metric ton of fish meal used in feeds yields about 10 tons of dressed catfish. Reduction in effluent volume through water reuse and effluent treatment in settling basins or wetlands does not appear feasible on most farms. However, some management practices are recommended for reducing the volume and improving the quality of channel catfish pond effluents .
  • Evaluation of a Bio-Organic Catalyst in Channel Catfish, Ictalurus punctatus, Ponds
    Julio F. Queiroz, Claude E. Boyd, Amit Gross
    Journal of Applied Aquaculture, 1998
    A bio-organic catalyst was tested in ponds used to grow channel catfish, Ictalurus punctatus, at Auburn, Alabama, for its effect on water quality, soil organic carbon, and channel catfish production. Although there were no significant differences (P > 0.1), ponds treated with the bio-organic catalyst tended to have higher concentrations of dissolved oxygen than control ponds during summer months even though all ponds were aerated mechanically. Data on water quality and soil organic carbon suagested that the bio-organic catalyst caused a slight but statistically significant inhibition of phytoplankton productivity, which in turn lessened the nighttime oxygen demand. Although fish production did not increase as the result of greater dissolved oxygen availability, fish survival was higher in the treated ponds (P = 0.1). At the maximum daily feeding rate of 75 kg/ha, water quality was not severely impaired in any of the ponds. The bio-organic catalyst product might have grcater benefits in ponds with higher s...
  • Evaluation of a Kit for Estimating Organic Matter Concentrations in Bottom Soils of Aquaculture Ponds
    Julio F Queiroz, Claude E. Boyd
    Journal of the World Aquaculture Society, 1998
    The Hach CEL/700 Organic Matter Laboratory provided estimates of organic carbon concentrations in pond soil samples comparable to those obtained by the commonly-used Walkley-Black method. Dry ashing at 350–400 C tended to overestimate soil organic matter concentrations, and this procedure requires too much equipment and laboratory expertise for use on most aquaculture farms. The Hach kit can provide practical aquaculturists a simple and reliable method for measuring organic matter in pond soils. Samples from brackishwater ponds should be treated with mercuric sulfate to prevent chloride interference and overestimation of organic matter.
  • Effects of a bacterial inoculum in channel catfish ponds
    Julio F. Queiroz, Claude E. Boyd
    Journal of the World Aquaculture Society, 1998
    . A commercial bacterial Inoculum cultured on site called Biostart was applied to three channel catfish Ictalurus punctatus ponds at Auburn, Alabama, USA, three times per week from May until October 1996. There were few significant differences (P × 0.1) in concentrations of water quality variables between ponds treated with bacteria and control ponds. In addition, bottom soil carbon and nitrogen did not differ between treated and control ponds. However, survival and net production of fish was significantly (P × 0.1) greater in ponds that received the bacterial inoculum than in controls. The mechanism by which the bacterial treatment influenced fish survival cannot be explained from data collected in this study. Further studies of probiotics are needed to define the potential benefits of these treatments to aquacultural production and to determine their mechanisms of action in pond ecosystems.
