Trout farms are one of the major sources of
pollution of highland streams and rivers, which are very
sensitive ecosystems otherwise scarcely influenced by
human activities. A trout farm with low annual production
was chosen for comparative monitoring of its effects
on the macrozoobenthos, epilithic diatom, and
potamoplankton communities in the receiving stream.
Research was conducted every 2 months during a period
of 1 year (one control point and three localities downstream from the farm). The fish farm discharge
induced moderate alteration of environmental factors
in the receiving watercourse, viz., significant increase
of the ionized and un-ionized ammonia fraction, dissolved
oxygen concentration, and biological oxygen
demand. Species richness and Simpson’s diversity index
did not change in any of the communities. Correspondent
analysis of potamoplankton community composition
clearly showed trout farm effects, thereby indicating
the need for reevaluation of saprobic ...valence values for
potamoplankton species. The complete lack of influence
of the trout farm discharge on the epilithic diatom community
is probably due to absence of significant changes
of phosphorus concentration in the receiving stream.
Effects of the trout farm on the macrozoobenthos community
were further characterized by 14 additional
indices. The percentages of Chironomidae larvae,
shredders, and total collectors; ratio of shredders to
collectors; and the family biotic index are suggested
as candidates for future multimetric index for measuring
of trout farm influence.
