a. This paper presents an account of fecundity studies into T. mossambica under Middle Central American conditions and limnological investigations into Lake Moyua/Nicaragua which have been performed during 1961/62.

b. Data obtained as to fecundity of T. mossambica are discussed in the light of the term prolificy and with regard to ecological and biological characteristics of Nicaraguan waters and native fish fauna.

c. A more detailed contemplation about the possible effects of a spread out or transplantation of T. mossambica into other Nicaraguan waters concludes the paper.
