There are two major sources of fish in Uganda; one is from aquaculture, the other from fishing in rivers and lakes. [1] Different types of fish flourish in different water sources. The waters of Uganda contain an impressive array of fish species—over 90 in all.
With its wide range of habitat types, Uganda is regarded as a hotspot for biodiversity. Some 345 species of mammals have been recorded in the country, along with 1,020 species of bird (around half of the total number found in Africa), 142 species of reptile, 86 species of amphibian, 501 species of fish and 1,242 species of butterfly.

The longline method developed in the 1980s for the effective exploitation of predatory fish e.g. Lates niloticus, Protopterus, Clarias, Bagrus, etc.A typical gear comprises a long length of a mainline 100–300 m (328.08–984.25 ft), rigged with monofilament twine (diameter 1.00-2.00 mm) or multifilament twine (ply 36–60) and bears short snoods 0.3–0.8 m (0.98–2.62 ft) carrying baited ...
Johann Christian Daniel von Schreber named Canis mesomelas in 1775. [12] It was later proposed as the genus Lupulella Hilzheimer 1906. [13]The black-backed jackal has occupied eastern and southern Africa for at least 2–3 million years, as shown by fossil deposits in Kenya, Tanzania, and South Africa.

It is known as cassava croaker or croaker in some parts of West Africa. [3] [2] The main diet are prawns and epibenthic crustaceans. [3]
Fish account for more than half of vertebrate species. As of 2016, there are over 32,000 described species of bony fish, over 1,100 species of cartilaginous fish, and over 100 hagfish and lampreys. A third of these fall within the nine largest families; from largest to smallest, these are Cyprinidae , Gobiidae , Cichlidae , Characidae ...
The genus Canis contains many different species and has a wide range of different mating systems that varies depending on the type of canine and the species. [27] In a study done in 2017, it was found that in some species of canids females use their sexual status to gain food resources.
