Tilapias in fish communities
1982
McConnell, R.H.L.
This paper reviews the information available on the ecology and behavior of tilapias in natural fish communities, the species interactions and factors controlling tilapia numbers, particularly conditions under which tilapias switch from growth to reproduction. Maturation and maximum sizes tend to be smaller (i.e., the fish "dwarf") in small bodies of water than in larger ones, and populations of fish with low weight for length switch to reproduction at a smaller size than those in which the fish are in better condition. Males tend to grow larger than females in 'dwarf' populations, even in species in which the two sexes grow to comparable sizes in large lakes
