Abstract

In recent years several studies have reported on chironomid production. The purpose of my paper is to evaluate the theoretical and practical aspects of the problems associated with the experimental investigations on chironomids, more specifically on Chironomus balatonicus, and to propose some solutions. A definition for biological production was selected from the traditional statements, which served as a basis for my study, then a new approach from cybernetical aspect is suggested. I consider eight tasks which are necessary to understand the importance of a quantitatively dominant species in the life of a water-body; these are the following: 1) Investigation of the complete life cycle under laboratory conditions. 2) Estimation of the production of one generation on the basis of breeding experiments. 3) Determination of the number of generations in a water-body. 4) The possibilities and ways of extrapolation from breeding results. 5) To establish the survival strategy and to estimate the elimination. 6) Estimation of the total production of the species in a water-body. 7) Possibilities for estimating the quantity of consumed nutrients. 8) Quantitative evaluation of the role of chironomids in matter circulation and in the energy budget of a water-body.
