Title : Maggot meal (Musca domestica), an alternative to fish meal in small and medium-sized fish farms in Burkina Faso
Abstract:
The availability in quantity and quality of animal protein sources of local origin is a concern of stakeholders in the aquaculture sector in Burkina Faso. This study consisted of finding the optimal conditions for intensive production of maggots in fish farms. It was conducted at the Lassalien Center for Introduction to Agricultural Professions in Bérégadougou from December to June 2022. The maggot production device contained 3 metal frames each topped with 4 strainers. To determine the effect of the attractants, we had 4 treatments distributed in each strainer, T0 (raw substrate), T1 (Substrate + Soumbala), T2 (Substrate + Animal blood) and T3 (Substrate + Fish viscera). To test the effect of temperature on maggot production, frame 1 was placed in the sun all day, frame 2 was placed for 6 hours in the sun and 6 hours in the shade and frame 3 was placed permanently in the shade for 4 days. As for the effect of humidity on maggot production, 4 treatments were also created. T0 was not watered, T1 received 2 liters of water on the first day, T2 received 2 liters for 2 days and T3 received 2 liters of water for 3 days. The results showed that with a temperature of 27.9 to 31.14 ºC there was a high production of maggots (1541g/m2) unlike a temperature of 30.07 to 33.37 ºC (402.25g/m2). The variation in the humidity level of the substrate made it possible to increase the production of maggots (1227g/m2 at frame n°2). Tests have shown that the best substrate is fish viscera (1541g/m2 for frame n°3).
Audience Take Away Notes:
