Aquaculture

You are also encouraged to view the “Fisheries and Ocean Economy” and “Aquaponics” pages.

The primary types (or branches) of aquaculture are marine aquaculture (saltwater / coastal), freshwater aquaculture (fresh water / inland) and brackish water aquaculture.

  • Marine aquaculture is a branch of aquaculture involving the farming of marine plants and animals which is conducted in the open ocean, in enclosed sections of the ocean, or in tanks, ponds or raceways which are filled with seawater.
  • Freshwater aquaculture is a branch of aquaculture involving the farming of freshwater plants and animals which is conducted primarily in ponds, open water cages or tanks.
  • Brackish water aquaculture is a branch of aquaculture involving the farming of fish and crustacea found in the saline waters of creeks, lagoons and estuaries.

 

Freshwater species are generally farmed in recirculating systems, earth ponds, cages or raceways whereas marine fish are farmed in onshore recirculating systems or cages in sheltered bays. The marine molluscs are farmed on rafts or longlines, and abalone are produced in tanks through which marine water is pumped continuously.

Aquaculture has food security, job creation and export potential.

South Africa: imports and exports

  • South Africa remains a net importer for aquaculture products (International Trade Centre, 2021).
  • Nonetheless, sub-Saharan Africa as a region presents a good opportunity for fish farmers in South Africa. South Africa’s tilapia exports increased by 8 950 % between 2012 and 2020, from 30 tons in 2012 to 2 715 tons in 2020. Malawi was the largest market destination for tilapia exports from South Africa, with over 2 000 tons during the 2020 marketing season, which is in line with the FAO’s predictions on the rising fish demand in Africa (NAMC, 2021).
  • The Fish SA brochure “Fishing for a sustainable and equitable future” at http://fishsa.org provides overviews of the fisheries (as opposed to aquaculture) exports of squid, hake, Cape horse mackerel, lobster and other species.

Local business environment

The annual A Profile Of The South African Aquaculture Market Value Chain (see the “Websites & publications” heading) covers aquaculture projects happening nationally.

  • South Africa (SA) accounts for less than 1% of global aquaculture production. Its aquaculture sector is in its infancy relative to the (wild) fishing sector, and as a result it is often viewed as support sector in response to increased demand for fish during a period of declining wild fish stock.
  • Aquaculture is diverse in both the farming methods used and specie farmed. Broadly the sector comprises of two culture environments with associated species: Marine: Abalone, Mussels, Oysters, Seaweeds, Dusky kob; Freshwater: Trout, Tilapia, Catfish, Ornamentals.
  • The SA aquaculture sector is characterised by three commercial anchor industries namely trout, abalone and mussels which jointly make up 92% of the total value of the sector, with total sales across the sector of R1 billion.
  • Abalone is the species with the highest value, and currently South African producers focus their marketing and sales efforts towards the Asian markets (in particular China).
  • Operations are concentrated in rural and semi-rural areas of South Africa (mostly in the Western Cape), and acts as an important contributor to economic development in these areas.
  • The sector supports approximately 6,500 jobs (direct and indirect).
  • In recent years the industry has expanded substantially with production levels increasing by almost 75% since 2013 to approximately 6,000 tons (Aquaculture South Africa, 2020).
  • The total sales value across the aquaculture sector in 2018 was approximately R1 billion excluding additional value generated through leisure and tourism, e.g. trout farming.

 

CHALLENGES

  • After a period of significant growth there has been a slowdown in activity due to increasing economic pressure (Covid-19 and other).
  • Significant operating costs including electricity, manpower, feed and services are hampering competitiveness in global markets
  • Market participants rely on costly private security service providers to combat stock theft due to a spillover from poaching and increased criminality in rural farming areas.
  • There is a high administrative burden across the sector with a plethora of regulations across different levels of the value chain.
  • The sector faces similar challenges to Agriculture and requires similar support structures relating to breeding programmes, research, globally competitive farming practices, feed formulation, disease control, and market access.

 

Further reference:

  • The Aquaculture Association of Southern Africa presentation to the Portfolio Committee on Environmental, Forestry and Fisheries (June 2020), from which the above points are taken, sets out the challenges of abalone, trout, mussels, tilapia and catfish sectors. It also sets out a projected path post COVID-19. A more recent fisheries report back (2023, March 28) – as opposed to aquaculture – gives feedback on abalone and other species in the wild.
  • The DALRRD-NAMC TradeProbe Issue 85 (May 2021) includes the report “An analysis of the South African aquaculture market and opportunities“.
 

Heart of Abalone – Agritourism Hermanus

 

For the newcomer

Several articles are available to the prospective fish farmer, mainly with headings like the following:

 

1. Market

Do you understand the market you plan to supply?

2. Species Choice, Climate & Infrastructure

The species selection will in turn drive the choice of infrastructure that is most appropriate for your climate, market requirements and skill of the management.

3. Scale of Operation & Expansion Rate

The market information you obtained will guide you in terms of an appropriate scale on which to start the business and according to which expansion should occur. Essentially there are two options:

  • start big and bring in skilled management
  • start small, learn from mistakes and grow with successes. (The second option is strongly recommended for new comers to the industry).

4. Technical Skills

Knowing the species and infrastructure types you will be using will guide you towards the skill sets you require.

5. Feed Supplier

Feed makes up more than 50% of operating costs. Don’t skimp on costs – quality is important!

6. Site Selection

Consider not only the water supply, climate and other onsite considerations, but also the related matters such as selective advantages offered by different sites in terms of labour source, buildings available, gravity fed vs pumped water supply, road quality and distances, electrical supply and telecommunications.

7. Capital Requirement

Having completed all the steps above you will have a clear idea of how much capital you require for construction, for cash flow through the lowest point in the budget and a healthy reserve for just in case. Insufficient capital can quickly starve the life out of a business, even a very profitable business!

8. Legislation

The final step in the planning, or the first in the execution, is to appoint an environmental consultant to obtain the permits for you. A good service will be expensive but an essential step in the process. Going through the steps above carefully and with attention to detail will give you the best possible chance of succeeding in the very exciting industry.
