The two photos show how fish farmers design a fish stall and display their fish. These photos were taken in Temerloh District, aka where Pangasius is the most famous and popular fish species in this region. This catfish was introduced from Thailand in the 1980’s and was successfully induced bred in captivity.

The inserted photos show a case of confiscated catch from Lake Malawi. The illegal size of the catch that seems a mixture of tilapia species represents almost all of confiscated fish.

The inserted photo shows the excavators during the construction of new fish ponds in Nepal. There is a small ongoing support program “Mission Fish” of the Ministry of Agricultural Development through which about 10-15% of the construction cost is covered as a subsidy.
Rather than pond construction and under the “Mission Fish” program, the government provides subsidies for increasing pond size or buying main production inputs such as fish feed or fingerlings. The support is provided to individuals, groups or families.

This is an annual event which is carried out at an aquaculture facility located in Muzaffar, Pakistan. This particular event took place on the 6th of November 2013. About 100 fish farmers from southern Punjab attended this event. The field day targeted to promote aquaculture and in particular tilapia culture in the region keeping in mind that tilapia culture is new in Pakistan and so many of the participants do not culture tilapia at the moment. In addition to the fish harvest, the event included a seminar on tilapia culture. Tilapia shown in the photo is the all-male of the GIFT strain of Nile tilapia, Oreochromis niloticus. In general, the average production of tilapia in the shown facility is about 7-8 tons/ha which are marketed in Lahore and nearby cities.

Arapaima gigas is Known as paiche in Peru and pirarucu in Brazil and Colombia. This species is one of the largest freshwater scaled fishes in the world. Paiche is characterized by its excellent high growth rate, no intramuscular spines, and tolerance to low oxygen as the species is an air breathing fish.
The fishing pressure has placed the wild populations of the species at risk leading to listing the species as endangered by the Convention on International Trade of Wild Fauna and Flora Species and placing this species is in the CITES II section (strictly regulated and controlled commerce). Thus, paiche has to be exclusively produced in aquaculture facilities including its fry production which has been already achieved. Moreover, farmed arapaima has to be certified by CITES authorities for export and import.
The species enjoys high demand in the amazon region. Also, preliminary market survey suggests a high market demand which could be established in the international. All of the above encouraged the farming initiatives of the species.
Because of the short history of arapaima farming, some management methods and facilities such as ponds and cage have been explored. For example, due to the carnivorous feeding habits of the species, protein-rich diets are being used. In line with that, research efforts are underway attempting to develop feed formulations with reduced costs and efficient FCRs. The forage system has been practiced by small-scale producers in which the species are stocked along with sufficient density of native forage species such as bujurqui and/or mojarra which secure a forage base for optimum growth of “paiche”. However, the present video shows that the farm relies on artificial feed; one may notice the large size of pellets used compared to smaller species. It may worth mentioning that the training of “Paiche” to consume artificial feed has been considered a key characteristic towards the farming of the species. Initial practices indicated the ability of “Paiche” to consume artificial feed of 40 -50% protein and reach a weight of about 12 kg after 12 months of growth.
This video was filmed in a fish farm upon harvesting using net seine then after shows the harvest in a plant where processing and packing took place.

This 4-slide information bite addresses the liming of fish ponds including the different purposes of liming as well as types of lime and criteria of each lime form. The applications of lime has been addressed and supported by photos. Determining the quantity and need through analysis has been also covered.

This traditional method/gear is locally named “Khora jal”. The photo shows the practice of setting the lift nets “Khora jal” in Ghagot river, Gaibandha sadar Upazila, Gaibandha District. Khora jal is one of the mostly used fishing gears in flood plain during the rainy season. This triangular net is made of mosquito net attached to its structure which is made of bamboo. This gear is commonly used in the morning and during night. The target catch of “khora jal” is small indigenous species. A fishing survey showed that four species of fish were among the catch of “Khora jal” which are Labeo rohita, Labeo calbasu, Silonia silondia and Eutrophiichthys bacha.

The inserted photos show the delivery of fish fingerlings to peasant fish producers as a sideline activity. This picture was taken in one of the provinces of Mozambique during a FAO regional project (SADC countries) financed by Sweden and Belgium. This province had a governmental experimental, demonstration (including integrated fish-duck and fish rabbit) and fingerling production farm between the years 95-97.
Note: SADC stands for “Coastal Countries of Southern African Development Community” with member States of Democratic Republic of Congo, Mauritius, Mozambique, Namibia, Seychelles, South Africa and Tanzania.
