Opsomming
| Beskrywing |
Afrikaans: Rooiknorhane word op of naby die seebodem in dele van die Indiese en Stille Oseane aangetref. Aan die Nieu-Seelandse kus is hulle oral behalwe in die suidelike fjords aanwesig. Hulle is volopste noordwaarts van die Chathambank in vlak waters, minder as 55 meter, oor 'n sanderige of modderige seebodem.
Rooiknorhane leef sowat 16 jaar en word op twee tot drie jaar ouderdom geslagsryp wanneer hulle ongeveer 23 cm lank is (van neus tot stertvurk). Op daardie tydstip vertraag hul groeitempo en bereik hulle geleidelik 'n maksimum lengte van ongeveer 42 cm. Wyfies groei vinniger en word groter as mannetjies, maar groei verskil ook na gelang van ligging. Rooiknorhane aan die Suid-Eiland se ooskus groei vinniger as dié in ander gebiede. Rooiknorhane gebruik hul borsvinne om te kruip, of as tasters, of om hul prooi na oopwater te verskrik waar hulle gevreet kan word. Rooiknorhane vreet krappe, garnale, klein vissies en wurms.English: Red gurnard are found on or near the seabed throughout parts of the Indian and Pacific Oceans. They are found around the entire New Zealand coast (except southern fiords). They are most abundant north of the Chatham Rise in shallow waters, less than 55 metres, over a sandy or muddy seabed.
Red gurnard live to about 16 years and reach sexual maturity at two-three years of age when they are around 23 cm (from the nose to the fork in the tail). At that time their growth rate slows and they gradually reach a maximum length of around 42 cm. Females grow faster and larger than males, but growth also varies by location. Red gurnard off the east coast of the South Island grow faster than those in other areas. Red gurnard use their pectoral fins for ‘walking’, as feelers, and to scare their prey into the open where they are eaten. Red gurnard eat crabs and shrimps, small fish and worms. |
