The chosen species to be cultured is the first consideration for any project. The species requirements determine every aspect of the project and is the paramount consideration for both design parameters and for the projects' profitability and feasibility.
Certain species requirements must be known to develop an operation and system accordingly. These include; water parameters, nutritional requirements, growth rates, metabolic profile and life stage husbandry requirements. All should be accounted for in as much detail as possible to tailor the system accordingly. A system built to the profile of the chosen species will allow the optimal growth rates to be achieved and also be an efficient system to operate.
Some species such as "tilapia", are less technically demanding to design systems for which is a function of its' natural life history and physiology. It is a species that is well adapted for living in high densities in the drying pools of East Africa, able to live comfortably within a varied range of conditions and so the requirements of this species are not for extremely refined levels of water quality. Other species by contrast, such as Atlantic Salmon, require a much increased level of water processing technology to maintain well oxygenated, low CO2 levels and reduced nutrient content within the water column and would not survive in water conditions tilapia would thrive.
AES encourages clients to consider and research their candidate species carefully, particularly when planning for RAS production. RAS facilities have to compete with products that may not have the same level of overheads (i.e. pond aquaculture) or a market to accept/ understand the premium quality prices.
Aqua EcoSystems has worked with numerous species within land based systems, including tropical shrimp, tilapia, sea bass, turbot, sturgeon, salmon, carp, trout, yellow tail tuna, sea bream and perch;
