Salinity tolerance of European catfish (Silurus glanis Linnaeus, 1758) larvae
Keywords:
European catfish (Silurus glanis L.), larvae, salinity tolerance, sodium chlorideAbstract
The aim of the study is to establish the salinity tolerance of European catfish larvae towards
different concentrations of NaCl. The experiment is carried out with 120 fish (body weight 70.2 ±
12.05 mg and total length 22.07 ± 1.33 mm). Three concentrations of NaCl (1.5%, 3% and 5%) are
tested at different exposures. The studied individuals showed tolerance towards 1.5% NaCl solution
for 15 and 30 minutes exposure (Variant A1
& A2
), 3% NaCl – for exposure of 5 minutes (Variant
B1
) and 5% NaCl – for 1 minute (Variant C1
), which means that these concentrations at the respective
exposures can be used for the prophylactic treatment of larvae. Saline solutions of 3% NaCl for 10
minutes exposure (Variant B2
), as well as 5% NaCl for 3 minutes exposure (Variant C2
), are not in the
salinity tolerance range of the studied species due to reported mortality of 5%, respectively, are not
recommended for use in fish farming practice.
