Fishing is the last form of modern food production that conforms to a hunter-gatherer modus operandi. Until the mid-20th century, man considered the world’s oceans an infinite resource and there was little incentive to cultivate aquatic organisms using modern agricultural techniques. That perception has changed, especially in the last decade or two as wild fisheries production stagnate - due in large to industrial fishing fleets taking their toll on wild fisheries stocks.
Aquaculture has now become an essential component of the global food production system - one that holds great potential for food security and environmentally conscientious food production.
All of them!!!!! Hopefully, one day! Tilapia, kob, grunter, stump nose, prawns, crabs, clams, seaweed, samphire. All of the natural bounties found in our Zululand estuaries.
We previously bred and reared dusky kob and spotted grunter, but after learning a few lessons, we changed focus to Mozambique tilapia. We maintain broodstock for several of the above-mentioned species, but currently rear only tilapia fingerlings in our hatchery.
Traits that make tilapia an ideal species for farming include their rapid growth, prolific breeding abilities, mainly herbivorous diet, and white, succulent flesh. They also occupy a lower trophic level in the estuarine ecosystem compared to a dusky kob, making them a more sustainable option, and one that aligns with the philosophy of integrated multi-trophic aquaculture (IMTA), More on this topic later though.
In the first quarter of 2020, we will harvest our first pond of Zini Saltwater Tilapia, ramping up production from about 5 to 15 tonnes per month by mid 2021.
Even with the benefit of hindsight, the relatively infantile modern aquaculture industry has had many of the same negative environmental impacts that are associated with modern agriculture. Modern fish farms, generally in the form of high-density monoculture farms stocked with high trophic level species such as Salmonids, have severely damaged some of the environments in which they operate. This form of farming also demands huge quantities of fish meal and oil, derived from severely strained wild fisheries stocks.
Zini Fish Farms subscribes to a different method of farming. The location and nature of our facility allows us to emulate a natural estuarine environment in our earthen ponds. By encouraging and enabling the formation of basic ecosystems comprised of all sorts of organisms, we strive to recreate a far more effective and natural system of producing food.
It is the way that we try to farm and eloquently expressed in Wikipedia…..
“Integrated multi-trophic aquaculture (IMTA) provides the byproducts, including waste, from one aquatic species as inputs (fertilizers, food) for another. Farmers combine fed aquaculture (e.g., fish, shrimp) with inorganic extractive (e.g., seaweed) and organic extractive (e.g., shellfish) aquaculture to create balanced systems for environment remediation (biomitigation), economic stability (improved output, lower cost, product diversification and risk reduction) and social acceptability (better management practices).
Selecting appropriate species and sizing the various populations to provide necessary ecosystem functions allows the biological and chemical processes involved to achieve a stable balance, mutually benefiting the organisms and improving ecosystem health.
Ideally, the co-cultured species each yield valuable commercial "crops". IMTA can synergistically increase total output, even if some of the crops yield less than they would, short-term, in a monoculture.“
