Abstract
Herbivorous fish living in Lake Tanganyika rely on algae as their main source of food and are constantly feeding on low quality (low energy) food. The lake is warming leading to fewer nutrient upwelling’s that are likely limiting the amount of energy available to fish. I calculated an energy budget to compare energy intake against energy expenditure of the African cichlid,
Tropheus duboisi
, by measuring metabolic rates at rest, while feeding, digesting and being aggressive as well as the caloric content of food, feces, and urine. Fish fed a low quality diet of algae contaminated with sediments had lower growth rates, but they had no significant differences in daily behaviors. As Lake Tanganyika warms I would expect fish living in the lake to have lower growth and reproduction rates. This could be detrimental to the fish populations, the ecosystems of which they are a crucial part, as well as for the many people depending on the lake for food.
