Compartmentalisation in aquaculture production systems.
Compartmentalisation is a new tool for disease management within a country. In aquaculture, the successful application of compartmentalisation is largely dependent on the system of production and the epidemiology of the disease(s) for which the compartment is being defined. Therefore, compartmentalisation may not be universally applicable across all systems and diseases. The paper examines the ...
متن کاملBiofloc Production Systems for Aquaculture
Biofloc systems were developed to improve environmental control over production. In places where water is scarce or land is expensive, more intensive forms of aquaculture must be practiced for cost-effective production. There are strong economic incentives for an aquaculture business to be more efficient with production inputs, especially the most costly (feed) and most limiting (water or land)...
متن کاملApplication of Biosecurity in Aquaculture Production Systems
A significant challenge to the expansion of aquaculture production is the outbreak of disease. Potential economic losses from disease outbreaks are significant, and can affect the survival of the industry. The occurrence of disease is a combination of the health of the animal, the condition of the environment, and the presence of a pathogen. The poultry industry has implemented a biosecure prod...
متن کاملBiodegradable polymers as solid substrate and biofilm carrier for denitrification in recirculated aquaculture systems
A simple process for nitrate removal is proposed for its application in aquaculture. Biodegradable polymer pellets are acting as solid substrate and biofilm carrier for denitrification. Laboratory experiments with conventional aquaria and fish were used to examine the feasibility and a first evaluation of the process performance in a recirculated aquaculture system. All over the test-period the...
متن کاملEffects of sumithion on growth and production of phytoplankton and zooplankton in aquaculture ponds
Sumithion is an organophosphorous pesticide widely used to control tiger bug in the fish larval rearing pond. The present study was aimed to investigate the effects of sumithion on plankton population abundance in aquaculture pond. The experiment was carried out with three treatments, i.e., ponds with no sumithion (T1), with 1.0 ppm sumithion (T2) and 2.0 ppm sumithion (T3). The water quality p...
