Uku (Gray Snapper)

Uku or Gray Snapper is found in the tropical Indo-Pacific Ocean from East Africa to Hawaii, Japan, and Australia. These snappers are not considered one of the heavily managed “Deep Seven Bottomfish” in Hawaii and live in much shallower depths of less than 1000 feet.

Uku is blue-green in color on the upper third of its body, fading to grey-white on the lower two-thirds. Uku have long slender bodies with a deeply forked tail. They have a heavy bony head with a distinct horizontal groove in front of the eye and large canine looking teeth. They are one of the most popular deep-sea bottomfish harvested in Hawaii by landed weight.

Uku (Gray Snapper)

Uku reach sexual maturity at about 16 to18 inches in length, or four years old. Like many other bottomfish, Uku reach peak spawning in the summer months, but spawn a little earlier, beginning in May and peaking in June. By November, most Uku have completed spawning. Their pelagic eggs are released into the water column. The pelagic larvae float in the ocean for about 25 days until they move to deeper water before settling down on the ocean floor where they will spend the remainder of their adult life. Adult Uku inhabit open waters of deep lagoons, channels or seaward reefs. They are primarily solitary except when spawning in groups. They feed mainly on fishes, but also shrimps, crabs, cephalopods and planktonic organisms.

FISHERY OPENINGS
Hawaiian Bottomfish by Rod & Reel Sep 01 - Aug 31
These crabs mate at the time of maturity, which is approximately 3 years of age. Females are smaller than males; this is because the development of reproductive tissues required more energy for females, leaving less energy available for continued body growth. They grow through a process known as molting—regularly shedding their shell and growing a new, larger one. They continue to molt and grow after they have reached sexual maturity. During the breeding season, the crabs leave their borrows in a phenomenon characterized by mass mate-searching events. Once mating/fertilization has occurred, females spawns in the water. The larvae released during the rainy season develop in offshore waters and return to coastal waters five to eight weeks after larval release.
Mangrove crabs are important fishery resources in all Brazilian coast, mainly in the north and northeast where many fishermen depend upon their catch. In addition to its social and economic importance, the mangrove crab is a “keystone” species in ecosystem, they playing an important role in the processes of nutrient cycling and energy transfer.

Fishing Methods
