Yellow-eye mullet head

Description[edit]

yellow-eye mullet are small, near-shore fish that usually reach 30-40 cm. Yellow-eyed Mullet fish is gray-green at the top, silver at the bottom, yellow at the bottom, bright yellow eyes. They like to feed on algae on rocks and eat some tiny reptiles. Although yellow-eye fish tastes good, they are most often used as bait fish. Due to their long relationship. Yellow-eye mullet is considered to be the best bait for capturing larger species. [2]Freshly caught mullet fillets, oozing blood and juice, are irresistible to almost any fish in the sea. They also have sharp heads and mouths, and the scales on the body are particularly small and thin and are very easy to fall off. Unlike most fish, it has two ridges, the first with 4 thorns and the second with 1 spine and 9 rays. These fish are olive or blue-brown with silver on both sides and bright yellow or gold eyes. The fins have brown edges. [3]They can live in water depth ranging from 0-50 m, but usually, stay in 0-10 m depth. They are most comfortable in temperature ranging from 14 to 24 degree Celsius, with the upper tolerate temperature of 28 degree Celsius and the lower limit unknown.

Distribution[edit]

Natural global range[edit]

Southwest Pacific, Also from Western Australia, Southern Australia, and Tasmania.

New Zealand range[edit]

All over New Zealand and the Chatham Islands.

Habitat preferences[edit]

They usually live in shallow bays, ports and estuaries, feeding on a variety of foods, including algae, crustaceans, diatoms, mollusks, insect larvae, fish, polychaetes, coelenterates and fish eggs. [2] They often shoaling near the surface, but rarely enter freshwater. For example, Lake Ellesmere, south of Christchurch will be found at any time of the year, but their spawning takes place in the sea. [3]

Life cycle/Phenology[edit]

The maximum age of yellow-eyed Mullet is estimated to be 7 years old. They lay their eggs between December and March, but some believe that spawning may also occur in winter [4]. They usually lay their eggs in summer and autumn coastal waters or in the estuary. Each fish can release up to 680,000 eggs. They may live for seven years and mature in 2-4 years. Female grow faster and are more than male. [5]

Diet and foraging[edit]

They are omnivores that feed on benthic debris, algae and small invertebrates, including plankton and eggs of other species. They are filtered from the sand through the mouth and cockroaches. Ingesting a certain percentage of sand helps to grind food in the muscles of the stomach

Predators, Parasites, and Diseases[edit]

In the natural food chain, they are preyed by larger predators such as dolphins and killer whales. Since they are usually used as bait fish, most large carnivorous marine life can be used as their predator.

Cultural uses[edit]

They have two commercial fisheries. One is the marine beach fishery, the goal is to lay eggs for adults, their caviar is very precious. Demand is high in Australia and overseas. It can be sold fresh, or smoked or dried. Beach fences are used for this type of fishery. The second method of commercial fisheries in the estuary fishery. This accounts for the majority of mullet fish catches. Yellow-eye are caught throughout the year, but most of the capture occurs in late summer and autumn. Coastal collection gill nets and tunnel nets are the main gear forms used in the fishery. People usually look for shiny skin, solid meat, and a fresh marine scent when choosing fish. In the fillets, look for pink, grey, solid, shiny, moist meat without any brown markings or oozing water and a pleasant fresh marine scent. [6]
