Food security is threatened by the global increase of human population, climate change, inequality of wealth distribution, the state of natural resources, peace and sustainability, among others. Aquaculture has become an important part of the food supply, hence contributing to food security. Sustainable fish production, which represents an important affordable protein supply, should therefore involve feed formulation and production techniques that are not dependent on fish meal as the protein source. It is on this basis that bioeconomy becomes very important to promote the resourceful use of biomass for feed, food, biomaterials, and bioenergy. This study presents housefly maggot meal as an efficient alternative protein source to fishmeal and a valuable bioresource. Clarias gariepinus fingerlings (male and female) were fed maggot meal supplemented diets for 24 weeks and we assessed their growth and gonadal development. The findings of this study revealed that maggot-meal-enhanced diets promoted growth and faster gonadal development in fish. Maggot meal represents a quality alternative protein source to fish meal and an excellent bioresource, which can help us attain sustainable aquaculture production.

Heterotis niloticus is a fascinating freshwater fish species popularly referred to as the African bonytongue. It offers great potential for aquaculture due to its rapid growth, flesh quality, adaptability to low oxygen environments, and high market value. Domestication efforts for this species have been initiated to optimize its production and meet the increasing global demand for sustainable protein sources. This review explores the current state of H. niloticus domestication and highlights the key challenges and opportunities. Despite their promising potential, several obstacles remain, including the development of efficient hatchery techniques, optimization of feed formulations, and disease control. Overcoming these challenges is essential to promote the full potential of H. niloticus aquaculture and contribute to improved food security. Future research should focus on refining breeding programs, improving water quality management, and exploring innovative aquaculture systems. Policy support is key to driving investments, innovation, conservation efforts, and the sustainable development of H. niloticus aquaculture.
