Y. Takemon et K. Nakanishi, REPRODUCTIVE SUCCESS IN FEMALE NEOLAMPROLOGUS-MONDABU (CICHLIDAE) - INFLUENCE OF SUBSTRATE TYPES, Environmental biology of fishes, 52(1-3), 1998, pp. 261-269
Individual variation in body size, home range size, and reproductive s
uccess among Neolamprologus mondabu (Cichlidae) females were investiga
ted with reference to substrate types in the littoral zone of northern
Lake Tanganyika. Larger females occupied sandy substrates and smaller
ones stony substrates. Female reproductive success, estimated as the
number of offspring successfully released per month, was higher on san
dy substrates than on stony substrates. This may be attributable to hi
gher spawning intensity and better protection of broods against predat
ors in open, sandy habitats.
