 Aquaculture 

Description of the Industry 
The Cacadu District Municipality have identified the Aquacultural sector as a priority investment sector due to its vast growth potential and the significant global demand. The Eastern Cape is the second greatest producer of aquaculture in the country and therefore the CDM can benefit from this as it provides a baseline for further production activities.
 
The aquaculture industry consists of the farming of aquatic i.e. freshwater and marine organisms such as fish, molluscs, crustaceans and plants under controlled conditions which include interventions such as regular stocking and feeding during the rearing process to increase production. The South African marine aquaculture sub-sector is relatively small, but the growth potential over the next few years is very promising, this is as a result of the leveling off of worldwide fishery production and an expected rise in demand and therefore price for high value fishery products.
 
The table below provides an indication of the number of aquaculture enterprises or producers per province. It can be seen that the Eastern Cape Province has the second highest number of producers (19), compared to the Western Cape with 33 producers. Thereby establishing the Eastern Cape Province as a leading aquaculture producer.

From the above table it can be seen that the Eastern Cape contributes the most to the marine sector production and very minimally to that of the freshwater sector, where only 8.6% of the value of production was generated for marine fish and 3.7% to freshwater species (table 3).

The most common types of freshwater aquaculture species are ornamental fish, tilapia and trout. Other species are cultivated locally including carp and catfish, and internationally such as bait fish, sport fish, laboratory fish for experimentation, industrial and medicinal products, and as native fish to mitigate losses to the rapidly declining wild fish populations. The most common marine aquaculture species are oysters, abalone, mussels and saltwater fish.

Value Chain 
The aquaculture value chain consists of a number of primary activities that constitute the basis of the aquaculture industry. The ‘input supply’ stage consists of 3 critical elements: that of the species stock supply which originates from hatcheries or nurseries; the feed supply which is either imported or produced locally; and the labour supply required to carry out the various activities within the hatcheries. The second element is that of ‘production technology’ where the technology utilised depends on the type of venture to be carried out i.e. whether cages or ponds are utilised etc; as well as the various transportation and other capital equipment required to assist the growing of the species.
 
The third stage is the maturing of the species and where they reach the correct age for distribution and sale. This then makes up the next step, where the trading of the particular species is underway, either to the local or export market. The traders will either process the species themselves or sell it to processors who in turn sell to the consumers. Supporting products and services include the research and technology element of this value chain.

Global and National Market Trends

The total production size and value of the South Africa marine and freshwater aquaculture sub-sectors in 2008 was 3, 664 tons, representing a product farm value of R327 million. The production volume increased at an average rate of 7.8% between 2005 and 2008, and total rand value at an average annual rate of 32% over the same period.
Table 4 and 5 below outline the total size of value of production from 2005 to 2008, showing a relatively steady growth within the freshwater sector (around 1000 tons), while the marine sector experienced modest growth during this period.

Abalone production dominates the value of production within South Africa, where in 2008 the value amounted to R268 million, generating over 80% of the total rand value of the aquaculture sector. The second largest contributor is that of trout production at R28 million, which compared to abalone is drastically smaller, representing 8.5% of the total. Koi and ornamental fish generated R11.5 million; oysters at R8.5 million and mussels at R6 million.
 
The Eastern Cape Province is the second largest contributor, where predominantly marine farms accounted for 18% of the total production representing 7% of the value of South African output in 2008. There are several aquaculture farms located in the CDM, in areas such as Port Alfred, Graaf-Reinett and Grahamstown.
 
The South African export market is mostly attributed to abalone production, where in 2008 the export of aquaculture was made up almost entirely of abalone, representing 24% of the total tonnage and 82% of the total value of South African aquaculture production. The provincial profile of marine and freshwater exports is presented in Table 6 below.

In 2008 the aquaculture products that were sold on the domestic market amounted to 2,711 tons which was valued at R58.7 million. Provincially, the Western Cape Province was the leading producer with 1395 tons worth R271 million, followed by the Eastern Cape with 593 tons of product worth R24 million.
 
The Eastern Cape and CDM has a well established and growing fishery sector, and is currently a net exporter of fishery products. However, most CDM fisheries are considered to be maximally utilised and high value product fisheries such as abalone, prawns and linefish are over-exploited. The projected increase in demand for high end fish products provides opportunity for substantial increases in marine aquaculture production. Domestic demand can also be met by imports; therefore the projected increase in demand simply and only provides an opportunity for the marine aquaculture sub-sector, if it is competitive. Furthermore, most ornamental fish sold in the province are imported, representing a further opportunity to produce them locally to reduce imports.
 
Area Identified and Land availabitilty
The Eastern Cape Province has the second longest accessible coastline, about 38% of which was deemed to have potential for marine aquaculture development. The major areas that are suitable for development are around East London and Port Elizabeth (Industrial Development Zones). Within the Cacadu District Municipality the ability to practice aquaculture is accessible within any of the areas, provided the correct infrastructure is available. However it should be noted that marine and freshwater aquaculture activities require different areas and arrangements that will be suited to adequately cater for their species.
 
Industry Associations
 
Abalone Farmers Association of South Africa (AFASA) has the capacity to organize collaborative research.
 
The Aquaculture Association of Southern Africa (AASA) has developed into a structure with representation from the various sectors contributing towards the aquaculture industry of the region, including marine species such as oysters, mussels, abalone and prawns; freshwater species such as trout, catfish, tilapia, ornamental fishes; as well as service providers such as feed companies, equipment suppliers and veterinary services.
 
Aquaculture Innovations are aquaculture consultants within the Eastern Cape, they provide assistance in developing business plans, feasibility studies, species selection, system designs, production audits and mentorship to all interested aquaculture parties.
 
The Aquaculture Institute of South Africa functions to provide an integrated and sustainable aquaculture sector for the Western Cape and South Africa in general.
 
Land and Climatic Characteristics
The high-energy nature of the South African coastline limits opportunities for sea-based aquaculture to a small number of sheltered bays and estuaries. Shore-based, pump ashore operations have been successfully developed for abalone and seaweed farming. Although South Africa possesses favourable environmental conditions for aquaculture, access to suitable sites, both sea-and land-based, has been identified as a fundamental constraint to the growth of the sector.
 
The greatest challenge that is experienced is that of acquiring the most appropriate land, the most suitable land is that of coastal land, however the price per hectare is extremely high which therefore pushes up the capital costs of the investment. Offshore activities are also limited since the South African coast lacks sheltered bays. Freshwater aquaculture activities require access to suitable water quantities and quality in order to function efficiently.
 
Infrastructure
The infrastructure required for aquaculture is extensive, there needs to be adequate transport networks, with effective transportation to guarantee the delivery of the products which are all affected by temperature and length of travel. Access to water, in terms of quantity and quality are essential as well as methods to treat the effluent water. The area in which it is situated should be free of flooding. There should be sufficient electricity and buildings in place to ensure the effective running of the facility. Consideration needs to be given as to where and how to source the feed for the respective species i.e. marine feed is imported, while freshwater feed is made in the Western Cape.
 
The CDM is well connected in terms of transport linkages as well access to electricity; the major limitation however, is that of water. 
 
Human Resources
The marine aquaculture sector is a skills-based industry at all levels, and, if it is to grow, human skills capacity needs to be developed in collaboration with the key stakeholders in the private sector, educational institutions and relevant government departments.
 
At present, formal training in aquaculture is only provided at a tertiary level. There is a significant gap between the qualifications of workers (who have secondary level education) and management (who are generally trained on a tertiary level). A need was identified to develop technical training and skills for workers. This would enable the industry to meet efficiency and transformation goals. The aquaculture industry has the ability to employ a large number of workers, and is therefore a constantly growing sector of the economy that will help to establish livelihoods for many individuals. The unskilled workers will need to acquire on-the-job training and mentorship from knowledgeable aquaculture role-players, however while they will gain knowledge and skills from training they will find it difficult to reach managerial positions without having acquired further education.  
 
Rhodes University situated in Grahamstown in the CDM is a highly recognized tertiary institute for marine fish research, which is advantageous especially since this section of the aquaculture industry has the most potential. Therefore there are opportunities to gain the skills that are required within this industry. Aquaculture Innovation is also located in Grahamstown and assists with trainings and offering of aquaculture courses to gain adequate skills in this sector.
 
Expected Return on Investment
The greatest potential and highest return on investment will be that of Abalone farming. This investment requires approximately R30 million to start-up operations; and profit will only be realized after 5 years. However, the market demand is significant as well as the illegal operations of obtaining Abalone from the wild makes it an extremely sought after species. The market is dominated by the export market where the main export countries are China and Japan, the price received is approximately $32 p/kg, including the shell.
 
Trout and ornamental fish farming is also a lucrative market; trout requires approximately R600 000 to start up, and will realize profits after roughly 1.5 years. It is a “safe” market because it is already well established; has refined technology and is a well known industry that receives a high market price. The approximate selling price is R35 p/kg when sold whole to processors. Ornamental fish is also a growing industry, and has significant potential since the majority of the ornamental fish are imported to South Africa; therefore a large local market exists that is relatively untapped. Unit value of ornamental fish is also far higher than that of any other specie.
 
Key Constraints
§         The experience of the local marine aquaculture industry to date reveals that growth has fallen far short of expectation, mainly due to an uncoordinated institutional environment, a lack of appropriate technology, difficulties in obtaining suitable culture sites, and inadequate public sector support measures to pioneer farmers.
§         Aquaculture is a form of intensive farming with relatively high unit production costs -compared to our industrial fisheries. The challenge is therefore to identify market opportunities for high value products that can be farmed profitably.
§         Production costs tend to be higher during the set-up phase of a new aquaculture sector, because production techniques have not been optimized, and economies of scale have not yet been achieved.
§         Without proper evaluation and mitigation of the impacts and implementation of responsible environmental management plans, aquaculture activities may degrade the ecosystems upon which they rely.
§         Access to appropriately structured, inexpensive funding has also suffocated the industry.
§         Identification of marine sites presents a problem for further development within this industry.
§         Illegal poaching operations compete with legitimate aquaculture operations.
 
Opportunities:
§         CDM could build comparative market advantages through various strategies including the use of indigenous species for niche markets; exploitation of local environmental advantages; the development of cost efficient technology suited to local conditions; the branding of locally produced species and a “clean, green” image.
§         Over fishing and depleted fish stocks globally translates into a growth sector for the future.
