What is blue cod?
Blue Cod is a fish found only in the waters of the ocean surrounding the rocky coast of New Zealand. In 1986 it was strongly hunted commercially and for recreation, which leads to its location in the quota management system. Depending on age and gender, the fish range of color from blue-green to brown blue is. Size and weight also vary, up to 23.6 inches (60 cm) to length and diameter of £ 8.8 (4 kg) weight.
These fish have always been an important source of food for people living in New Zealand. Native Maori used the fish as a terminal of their diet and called it raawar . Archaeologists found Blue Cod fish bones in ancient places of digging. These bones contributed to the average length of data monitoring over time, a number that indicates that the cod has risen to the size of excessive fishing.
New Zealand has the government has introduced a quota management system to monitor and restrict commercial and recreational fishing. Blue cod was one of the first 28 species fishing for this program in 1986. The number of ryB, which can be captured on a person ranges from 10 to 30 a day and the number changes on the basis of the region and the current fish population. All fish must be at least 11.8 inches (30 cm), otherwise they must be released back to the ocean.
Most of the blue cod population is concentrated in several areas, including Cook Strait, Southland, Fiordland and Chatham Island. As the lower inhabitants, fish live in sand and weeds at shallow water depths of up to 492 feet (150 m) deep. Over time, watching studies of blue cod has revealed that fish usually remain in the area they were born to and did not travel far during their lives.
The reproduction period begins at the end of the winter and lasts until late spring. The eggs emerge near the water surface and hatch over the floating for five days. The larvae of the blue cod remain near the surface for the Anopt Days, finally departure to start his life at the bottom of the dwelling.
