The photo shows a greenhouse-type hatchery for Nile tilapia, Oreochromis niloticus. The hatchery has been constructed at the Ruhila Aquaculture Development Center. It may be of interest to know, this type of tilapia hatchery has been designed by a colleague who attended an earlier EICA training course in 2010. The hatchery is in operation whereas about 5 million mixed sex tilapia fingerlings are produced. Arrangements for mono-sex tilapia production are in progress.
The produced fingerlings are distributed to farmers, where they buy at Tanzanian shiling 50/fingerling. Others are restocked in natural water bodies; demand for fish is not high in this area. Though, after awareness the number of farmers is increasing.

The photo shows a young angler catching a specimen of orange-spotted songkhla, Epinephelus coioides in Lake Songkhla, Thailand. This lake is largest natural lake in Thailand, located on the Malay Peninsula in the southern part of the country. The lake covers an area of about 1,040 km². The coastal Fisheries Patrols are in charge of enforcing fishery laws and regulations in Songkhla Lake.
This video was filmed in the Golinga Dam (Ghana). The two individuals are fishermen, one of them lives in Tamele Town while the other in Gbulahgu Village. In the video they are seen casting nets. The fishing boat (canoe) used is a 2-person boat and has a local name “Narin”; (Local Language: Dagbani).
The Principal fish species caught in the Golinga Dam are Nile tilapia (Oreochromis niloticus), Sarotherodon Galilaea, Tilapia zillii, Heterotis niloticus, Brycinus spp and African catfish (Clarias gariepinus).
It is of importance due to the fact that the Golinga Dam is the main source of cheap source of animal protein for the rural people living around the dam and also Tamale Township and beyond. Also a number of earthen fish ponds have been constructed for Community management and the dam serves the source of water for these ponds.
The water body shown in the picture is the Golinga Dam, located in the Tolon District of the Northern Region. It was a dam constructed to provide water for the rural communities surrounding it mainly for irrigation purposes.
The Boat is a hand dug canoe used for artisanal fisheries by the rural communities. They are usually made with wood materials from Odum or Wawa depending on the kind of wood the fishermen can afford. The men in the picture are just returning from fishing after having been casting their net for a couple of hours.
This water resource contributes approximately about 15 tons of fish annually to the fishery sector in Ghana. From previous data collected and information gathered from fishermen, there is a drastic reduction in the catch of fishermen mainly as a result of overfishing. The Principal fish species here are Oreochromis niloticus, Sarotherodon Galilaea , Tilapia zillii , Heterotis niloticus, Brycinus spp. and catfish. The major types of fishing done here is through the use of cast and gill nets with a few people setting traps.

Pearl farming is a growing aquaculture activity in Tanzania especially on small- scale projects which could offer opportunities for income generation for coastal communities in Tanzania.
The photos are for black-lip pearl oyster, (Pinctada margaritifera). The spats of the pearl oysters are collected from the wild. These pearl oysters are inserted with buttons inside in order to trap the pearl. This is based on the phenomenon of the formation of pearls inside the shell of certain mollusks as a defense mechanism against a potentially threatening irritant inside the shell.
The other photo is for a farmer showing the way to keep the pearl oyster under water for 9 months, so they don’t get lost. Farmed pearls are on demand for jewelry making. However, the ideal market for Tanzanian pearl continues to be a challenge to the pearl farming in Tanzania.
The two photos show fish ponds which are privately owned and located in Kisarawe district coastal Region, Tanzania. There are eight ponds of 20 x 25 meters each. Ponds are stocked with Nile tilapia, Oreochromis niloticus. The buildings shown in the photos is are chicken houses in which chicken are grown for meat while their droppings are s source of pond fertilization.
The photos show the sampling process of milkfish (Chanos chanos) and tilapia mossambicus (Oreochromis mossambicus) grown in an earthen fish pond located in Tanga region, Tanzania. This trial aimed to evaluate the performance of the two species in marine waters. The sampling was done to check the growth rate and the overall condition of sampled fish. In this particular sample and as the photos show, sampled fish were dominated by milkfish while tilapia was able to avoid the net used in the sampling.
The hatchery facilities shown in the photos are located in the Fish Culture Station Hydroelectric Itutinga, Itutinga, MG, Brazil.
The spawning activities of the hatchery focus on migratory species including curimba, curimatâ, (Prochilodus lineatus), Pacu (Piaractus mesopotamicus), piracanjuba (Brycon orbignyanus), dourado (Salminus brasiliensis), and pirapitinga (Brycon nattereri). The reproduced species are subjected to artificial induced breeding whereas the produced progeny are used for research, subsistence fishery and for a restocking program. Approximately one million fingerlings of mentioned species are produced during the breeding season (December – early March).
The photos on cage farming are taken in Fumas reservoir, Boa Esperança, Minas Gerais, Brazil. The altitude of this site is 775 meters whereas the temperature ranges between 18°C and 26°C.
The cages shown in the photos are rectangular with a volume of 18 m3 each. Cultured fish species include curimba, curimatâ (Prochilodus lineatus), Traira (Hoplias malabaricus), Nile tilapia (Oreochromis niloticus), Pacu (Piaractus mesopotamicus), piracanjuba (Brycon orbignyanus), and dourado (Salminus brasiliensis). Fish are stocked during December at an average density of about 20 fingerlings/m3 whereas the growing season lasts till March of the following year ending by harvesting of about 10 kg/m3.
Away from cage aquaculture, the sport and subsistence fishing are practiced in the Furnas Reservoir.
The photos show the stocking of fish fingerlings in a communal fish pond located in Nangwangwa village, Nkhotakota District in central region of Malawi. In such communal system, members are helping each other in fish farming operations. The stocked fish species are Oreochromis shiranus (Nkhututu) and Tilapia rendalli (Nungutchale). The area in the pond shown in the photos is about 400 m2. The photos show the involvement of women in aquaculture which is common in Malawi.
