ABSTRACT


Effects of total suspended solids in riverine water on embryonic development and larval survival, size, and malformation rate in pike (Esox lucius L.) were studied. Total suspended solids in concentrations even below 25 mg · dm-3 (the generally accepted threshold level) were found to inhibit fish embryogenesis by affecting fertilisation (% fertilisation: untreated, filtered riverine water and tap water: 75; 91; 85, respectively), perivitelline space formation (perivitelline space %: untreated, filtered riverine water and tap water: 29.77; 33.07; 29.68, respectively), organogenesis, and hatching (in riverine water – hatching began at 95 D° and terminated at 140 D°; in filtered riverine water – hatching began at 110 D° and terminated at 150 D°). The total suspended solids were also found to affect the larval size: the larvae hatched in water containing suspended 0particulates were smaller than those hatched in clean water (larvae hatched from eggs incubated in riverine water total length 9.34mm, filtered water – 9.82 mm); the larval malformation rate was higher in the suspended solids-rich water (% malformed larvae – 9.0) than in clean water (% malformed larvae 7.0).

Key words: fish embryogenesis, pike, pike embryonic development.
