Tołpyga Pstra - (Aristichthys nobilis) - Bighead carp

Tołpyga Pstra – (Aristichthys nobilis) – Bighead carp – Północną granicą występowania tego gatunku jest system wodny Rzeki Żółtej.

Tołpyga pstra ma rzadszy aparat filtracyjny niż tołpyga biała, więc jej głównym pokarmem jest zooplankton. Podobnie jak pozostałe ryby roślinożerne (czyli amur biały i tołpyga biała) ma niskie wymagania tlenowe. Tołpyga pstra osiąga masę do około 40 kg.

W listopadzie 2014 w Odrze we Wrocławiu złowiono osobnika o długości 122 cm, a kolejnego, o długości 120 cm, złowiono w grudniu 2015 r. w dolnośląskich stawach Jelcza-Laskowic.

hence the name bighead carp. FIGIS (2005) states that the length of the head is larger than body height and the mouth slants upwards and the lower jaw extends slightly over upper jaw. Their scales are very small. There are approximately 85-100 scales in the lateral line, and 26-28 scale rows above the lateral line. The fins of small specimens lack spines.

Large specimens have a heavy, stiff, non-serrate spine at the origin of the dorsal fin and a slightly stiffened spine at the anal fin origin. The dorsal fin has eight (rarely nine) soft rays, the anal fin has thirteen (rarely fourteen) soft rays. The gill rakers are long, comb like and close-set, not fused into a porous plate. The pharyngeal teeth count is 4-4 (The Gulf States Marine Fisheries Commission, 2003).By: Wikipedia
