is combined with a trawl net which lifts the krill to the surface [2][3][4] Their eyes are of medium size and are set towards the top of the head, indicating that they catch prey by moving into the water column from the seafloor. One possible explanation for why icefish were able to survive the mutational events that removed their erythrocytes is that because iron is a limiting element in the oceans, icefish found a way to thrive by not needing it for oxygen transport. [6] Because of their movement into the water column, fish are observed to feed on both the seafloor and in the water column. CCAMLR (Commission for the Conservation of Antarctic Marine Living Resources) was set up in 1980 under the Antarctic Treaty to manage and protect the marine resources in the Southern Ocean.

Fishing boats travel thousands of kilometres from the Australian mainland to catch fish in the deep, icy waters of Antarctica. To ensure that the fishery does not harm these other species, CCAMLR has set limits on the krill fishery. The Antarctic Peninsula has warmed an average ofthree degrees Celsius in the past 60 years, and all predictions indicate a continual steady warming. in this area, though there have been others in the past that In case you catch them accidentally, you can also release those fishes back into the water so that they can reproduce and grow in population over time. The high level of IUU fishing has had a negative effect on toothfish stocks but has also seriously affected other species in the food web including sea bird populations putting the future sustainability of both groups into question. is 620,000 tonnes, which represents approximately 1% of the They likely mature between 13 and 17 years of age (120-133 cm in length). pros - very enjoyable, peaceful, relaxing cons- carp fishing is one of the most common causes.

However, this also implies that over time, significant amounts of plastic waste will gather in our water bodies, which can take many years or even decades to decompose. Adaptive radiation is the rapid speciation of multiple species from a common ancestor to fill empty niches. To add to that, use of non-selective fishing gear, including longlines, trawl nets and gillnets destroy around 20 million ton of marine life, including, small dolphins, porpoises and whales.
