This course covers an array of theoretical knowledge with practical aspects pertaining to fishery husbandry practice and standards applicable to the modern aquaculture industry. Fishery Husbandry and aquaculture necessitates a full appreciation of the life support systems and optimum rearing environment. Thus very high quality conditions must always prevail in a fishery, including fine control of water quality, flow rates, oxygen saturation level and many other variables meeting strict life support requirements.
Species destined for food production and those classed as ornamentals or biosciencesshare common needs. Their fishery will require care and maintenance as do those in captive or in public aquaria. It is also vital to ascertain the feasible stocking density appropriate for specific species and size class throughout production. This Fishery Husbandry course will enable Participants to be competent with respect to the presentation of feed and feeding strategy for different species of fish.
The course will also emphasise good farm practice and record keeping of stock and management approaches. This course will be of value to any practising fish farmer or aquaculture management team, especial in dealing with disease identification and treatment/preventative routes.
By the end of this course you will be able to:
The module will include a core element addressing the major issues relating to the husbandry and welfare of farmed fish in particular. The conditions for the breeding, maintenance of ornamental fish will also be covered as this is an important area of interest. The following sections provide the basic for this module content.
Water chemistry and quality:
Key water quality criteria needed to sustain fish under varying production levels with emphasis on oxygen, ammonia and other nitrogenous excretions, their threshold limits for different fish species and measurements. The different techniques for water parameter measurements ranging from simple test kits to spectroscopic methods will be addressed.
Water quality and resource management:
The optimum conditions of supporting the maintenance and production as well as the health of various farmed fish will be an important component of this module. The related life support requirements and associated abiotic parameters such as dissolve oxygen, nitrogen loading and carbon dioxide, acidity (pH) levels will be noted as important to the efficiency of healthy aquaculture production The module will focus on salmonid species such as rainbow trout, warm water fish e.g. tilapia and carp as well as marine fish species and exotics in relation to their requirements.
Aquarium management and the development of RAS (Recirculation Aquaculture Systems):
New emerging engineering technologies will feature in this course forming the basis of RAS Recirculation Aquaculture Systems with full control and monitoring of environment featuring modern filtration systems, aeration and water treatment processes are important areas to be included. Management of fish stock from extensive to intensive production systems will be covered in the module and risks and benefits identified compared to more traditional methods of fish culture.
The assessment instruments for the module will be comprised of a single component contributing 100% of the marks for the module:
An assignment will be set requiring the analysis of a ‘real life’ system (in the work place). This may be an existing sector of the industry/business or it may be as a proposal for a new business venture. The participant will be expected to consider the key issues, strategies and developments which may be implemented to either improve the system, solve and problems or issues and improve efficiencies using the theory and knowledge covered by the module. Relevant analyses will be included to test the plan.
