Le séchage se fait sur les claies surélevées ou sur les treillis et concerne essentiellement le poisson de petite taille comme Lake Tanganyika sprat (Stolothrissa tanganicae) et Lake Tanganyika sardine (limnothrissa miodon). Les poissons sont exposés au soleil pendant une durée de 1à 3 jours suivant les conditions climatiques, jusqu’ à ce qu’ils soient relativement sec et peuvent ainsi être vendus sur les marchés à la longue distance.

Drying of fish is done as shown in the photos on raised racks or meshes and relates mainly small fish such as Lake Tanganyika sprat (Stolothrissa tanganicae) and Lake Tanganyika sardine (Limnothrissa miodon). Fish are exposed to the sun for a period of 1 to 3 days depending on weather conditions, until they are relatively dry and can be sold in the markets in the long distance.

Smoking is a method of preserving a food by smoke exposure. Traditionally, ovens consist of a pit about 30 cm deep, built by craftsmen processing before the smoking process. These traditional smokehouses, permanent or temporary, are often situated within a plot of artisans to enable them, usually women, to conduct jointly with other family activities.
Traditional smoking: The traditional procedure of smoking takes place just above the pit. Large branches of fuel wood are placed at the bottom of the pit and lit a bright fire. Fish is usually smoked in whole without prior removal of gills and intestines. The caudal fin of the fish is going into the hole of the gills and the fish and form a circle. These are then disposed one after the other on a branch timber which is then placed on top of the pit. A maximum of sixty four twenty fish (equivalent to eight to nine branches placed parallel one to another and carrying eight to ten fish each) can be smoke simultaneously.
“Chorkor fish smoking”: The smoker type chorkor has evolved from the traditional cylindrical furnace. Building of “chorkor” is based on compact clay or terracotta, and brick. The construction is easy and building materials are generally available at the village level. Trays are used in these smokers whereas the loading capacity of the smoker depends on the number and size of the trays. This system has proven to be in line with the traditions of smoking used by African women.

This video clip was taken in a fish farm located in Kafr El Sheikh, Egypt. The sampling practice highlights the followings:
The feed has been used to attract tilapia to the chosen place for sampling.
The operation was done very fast
When large biomass was caught in the seine, the release of a portion of caught fish was allowed to minimize the sampling stress
It is obvious; the sampling in this video was a sort of demonstration in a training program. Thus, not much effort was taken to reduce the jumping of specimens over the sampling seine to ensure a representative sample.

The photos show the facilities of a hatchery in the seed production of tilapia in Namibia. The earthen ponds shown in the photos are square of 225 m2 surface are (15×15 m). Hatched fry are stocked in aquariums and then after in plastic tanks which are furnished with a filtration system to purify the water. The 2-g fry produced during this phase are moved to nursing facility to produce the fingerlings that are required for grow out.

Intensive fish farming is practiced in cages in Ghana whereas fish production from cages dominates aquaculture production amounting about 85% of total aquaculture production in 2011 whereas the number of cages was 1525 covering about 23 hectares.

The photo shows the indoor facility of a fish hatchery which has been established in April 2010 the National Aquaculture Centre (NAC) at Domas, Zomba. The hatchery has been supported with the support from USAID through the Department of Fisheries. The hatchery includes three units which are namely broodstock unit, incubation unit and the nursery. Tilapia fingerlings amounted more than 2 million in 2010. The founder is represented by a total number of 2500 broodstock which were collected from the wild. It may worth mentioning that under the FAO-TCP, four catfish hatcheries have been established as pilot private sector hatcheries initiative.

The photo shows an extension activity on aquaculture as represented in delivering technical information to fish farmers through videos. There are other extension methods including Farmer-to-farmer exchange of technology, Farmer Associations and cooperatives, and field days.

In addition to the ecological role of sea cucumber in nutrient recycling, there is a growing demand on sea cucumber (known when processed as Bèche-de-mer) in Mauritius whether for food or for medicinal purposes. Starting 2005, the Albion Fisheries Research Centre (AFRC) has launched a program to develop technologies for the breeding and seed production of brown sea cucumber, Bohadschia marmorata and black sea cucumber, Holothuria atra. There are several methods to induce the spawning of sea cucumber including the injection of powerful jet of seawater and thermal stimulation.
