Özet

A public aquarium (or city aquarium) is the aquatic counterpart of a zoo, which houses living

aquatic animal and plant specimens for public viewing. The supply of the species to be exhibited

is one of the most important issues. The small-spotted catshark (Scyliorhinus canicula), is very

famous for public aquariums to the exhibition. Along the Turkish coast, bottom trawls primarily

take catshark. In this study, it was aimed that live S. canicula supply and their transfer to public

aquariums. Catsharks were obtained by commercial trawl at the three operations. Operations

were carried out in September 2019 in Sığacık Bay, Turkey. Totally 26 S. canicula was caught

and they had put into 50, 100 and 200-liter tanks for the transportation. In the transfer process,

the average, ammoniac, temperature, oxygen pH value and salinity values were taken and their

values are70 mg/l, 18.8 Co

, 7.16 mg/l, 8.03 and 39.8 ppt, respectively. At the end of the 3-hour

transfer period, all of the fish were successfully transferred to the quarantine process. After 1

week quarantine period, the fish were put into the aquarium to be the exhibition. Mainly

ammonia the other transfer water criteria such as temperature, oxygen pH value and salinity are

important for transportation. Because S. canicula start to release ammonia when get stressed.

Therefore, water criteria should be checked every 30 minutes and if necessary Amquel for

ammonia bicarbonate for pH added in transfer tanks. After 1.50 h later, all individuals were

successufully transported as live (100% survival rate) to the quarantine process.
