“…According to Lwamba (2015), temperature variations of water in ponds follow the periodicity imprinted by sunrise and sunset. These results are those obtained by Kiener and Therzien (1958) who assert that the variation of water temperature in ponds is closely linked to radiation solar. According to Rabemazava (1986), the fermentation of organic matter increases the temperature.…”

In order to promote the nourishment of carp in farming, four foods have been created from traditional raw materials and containing different quantities of locally produced banana flour 3%, 6%, 10%. We tested these foods which contain 36% crude proteins and 8% lipids on carp fry with an initial weight of 9g. After 50 days of experiment, the final weights of the fish fluctuated between 121.53g and 122.45g depending on the treatments used. The food containing 10% banana flour and the control food showed the highest growth and food transformation rates, with specific growth rates (SGR) of 5.18%/d and 5.14% /d as well as a conversion rate of 1.17 and 1.15 while the food with 6% banana flour obtained a SGR of 5.15 and a conversion index (CI) of 1.15 while that the food with 3% obtained a SGR of 5.14 and a CI of 1.16. Thanks to this test, we were able to observe the impact of bananas on the premature development of tilapia. We will continue to study the use of local agri-food by-products and waste in feeding this fish.

“…In Madagascar, A. bengalensis is known to inhabit altitudes higher than 900 m.a.s.l. (Kiener, 1963). Anguilla mossambica is a more generalist species and has been recorded along the entire length of catchments (Marshall, 2011).…”

“…This phenomenon has been observed in the western Indian Ocean region, with A. bicolor commonly found in the lower reaches of freshwater systems below 300 m.a.s.l. in Madagascar (Kiener, 1963) and below 100 m.a.s.l. in Mayotte (Valade, Hoarau & Bonnefoy, 2018).…”

These catadromous fishes face multiple stressors, including habitat alteration and deterioration, barriers to migration, pollution and the adverse impacts of alien species, but knowledge of eel species occurrence, abundance and ecology in Africa remains poor.2. This study investigated the present and historical distribution of anguillid eels and the potential associated drivers of declines at the southern extremities of their ranges in South Africa. Data analysed included sampling conducted in KwaZulu-Natal and Eastern Cape between 2015 and 2020, and secondary data extracted from databases, museums and local management agencies.3. The median extent of inland penetration increased as follows: 22 km for A. bicolor, 29 km for A. marmorata, 94 km for A. bengalensis and 293 km for A. mossambica.
