Microbial Diversity in Aquaculture Prawn Ponds [PDF]
The microbial populations of aquaculture prawn ponds waters and sediments wereinvestigated using a range of microbiological and microscopical techniques.There were twice as many microorganisms in the sediment in the inner parts of theaquaculture ponds (15.5 x 109 microorganisms/g sediment dry weight) than there werein the outer parts (8.1 x 109 ...

Aquaculture in Ponds, Raceways, and Tanks
1995An earlier chapter discussed aquaculture in natural and modified systems, those systems requiring little or no input by man to achieve a desired production level. This chapter deals with more advanced culture systems, that is, those requiring significant inputs by man in terms of resources, energy, and investment.

The role of microorganisms in aquaculture ponds
Aquaculture, 1997Microorganisms have major roles in pond culture, particularly with respect to productivity, nutrient cycling, the nutrition of the cultured animals, water quality, disease control and environmental impact of the effluent. Management of the activities of microorganisms in food webs and nutrient cycling in ponds is necessary for optimising production ...

Selection of aerators for intensive aquacultural pond
Aquacultural Engineering, 2013Abstract Aeration cost is the third largest cost in intensive aquaculture system after post larvae and feed cost representing about 15% of total production cost. Therefore, selection of aerators plays a major role in maximizing the profit in such system.

A water budget model for pond aquaculture
Aquacultural Engineering, 1998A water budget simulation model that can be used for forecasting water requirements for aquaculture ponds has been developed. Water sources considered in the model include regulated inflow, precipitation and runoff, whereas water losses include evaporation, seepage, effluent discharge, and overflow. The model has been validated for ponds located at the

Evaluation of the aquaculture pond water quality
2003, Las Vegas, NV July 27-30, 2003, 2003According to the questionnaire and the fish’s endurance to the factors of water quality, this paper brings forward five grades water quality standard, establishes the index system of the evaluation, and calculates and selects the thickness of index system of the evaluation. The evaluation model and method were established.

Development of a silt pump for aquacultural ponds
Aquacultural Engineering, 1989Abstract Silt and organic residues accumulate in prawn ponds over time reducing harvest efficiency and production levels. A floating silt pump controlled by two guide wires stretched above the water was developed to remove this layer of silt material.

A GENERAL MODEL OF THE AQUACULTURE POND ECOSYSTEM
Journal of the World Mariculture Society, 1984ABSTRACTA computer model of a fertilized warm‐water aquaculture pond has been developed. The model is intended to represent the pond ecosystem and its response to external stimuli. The major physical, chemical, and biological processes and parameters are included in the model.

Waste Management in Aquaculture Ponds
2013Su ürünleri yetiştiricilik faaliyetleri sonucu oluşan atıklar organik ve inorganik kaynaklıdır. Su ürünleriyetiştiriciliğinde organik atığın başlıca kaynağı yem ve fekal atıklardır. Bu tip atıklar ekosisteme girdiklerinde kafesaltında tabana çökerek sedimentte bir takım kimyasal ve biyokimyasal reaksiyonların meydana gelmesine ...
