Mackerel-like fish

Mackerel-like (Scrombodei) from a subspecies of the Perciformes, the biggest order of fish. Mackerel (Atlantic-, horse mackerel etc), tuna, swordfish and barracudas all fall among the mackerel-like fish. Globally it is a very popular fish and forms an important source of food and income for many people. Mackerel are pelagic fish that live in large schools. While swimming in large schools, mackerel-like fish confuse their predators with the silver-like brilliance from their scales. Island mackerel is the smallest with 2o cm, the largest is the bluefin tuna that can reach a size of over 5 meters.

Albacore tuna (Longfin tuna)

Albacore, white tuna, or longfin tuna is a tuna species that mainly occurs in sub-tropical and temperate waters. The meat of this species has a white colour which makes it easy to distinguish from other tuna species. Albacore is a relatively small species (max. 140 cm) and has a short life-span of 9 years. Albacore reaches sexual maturity at age 4-5 and lives in mixed schools with other tuna species like skipjack, yellowfin and bluefin tuna.

Explanation assessment

miscellaneous albacore fisheries in the Pacific Ocean are [MSC certified]. The American, Canadian, Japanese, and New Zealander  tuna fisheries use handlines and pole lines, hand operated and mechanised. The MSC certified albacore tuna fisheries on the Fiji and the Cook islands use longlinesLonglines (drifting):
A fishing method whereby a long main line (40-100 km long) with transverse lines with hooks with bait is expanded. The line floats on buoys in the water column.

The southern albacore tuna stockStock:
The fish of a particular species reproducing in the same area in the same period. 
is healthy and not overfishedOverfished:
A stock is overfished when the stock size has decreased so far that it can no longer produce a maximum sustainable yield. The size of the fish populations is insufficient to reproduce in the long term. 
. The fishing effort however is increasing a lot.

The [troll line fishery] or [ handline and pole line (mechanised) fishery] is a selective fishery and has little bycatchBycatch:
Species caught next to species targeted for fishery. By-catches can consist of non-commercial species and species that are too small, and can be kept (this part is sometimes called by-product) or thrown back into the sea (discards). 
. Any bycatch can immediately be unhooked and released with high survivability.

The WCPFCWCPFC:
Western Central Pacific Fishery Commission, an international organisation dedicated to the conservation and management of fish stocks in the Pacific Ocean.  
is responsible for the management of southern albacore tuna. This commission sets management measures and does stock assessments. There are no [catch limits] or quotaQuota:
The maximum amount of fish of a species that may be landed per country and per year; an instrument for regulating fisheries. 
. There is however an upper limit to the number of boats per country that can take part in the fishery. More effective measures are needed to regulate the [fishing pressure] and handle the problem of bycatch.

It is difficult to make statements on the state of the albacore tuna stockStock:
The fish of a particular species reproducing in the same area in the same period. 
in the northern Pacific Ocean, because of missing biological reference points. However, it appears to be healthy and not overfishedOverfished:
A stock is overfished when the stock size has decreased so far that it can no longer produce a maximum sustainable yield. The size of the fish populations is insufficient to reproduce in the long term. 
: The increment of young albacore is good and the stock balances around the [long term average].

The [troll line fishery] or [ handline and pole line (mechanised) fishery] is a selective fishery and has little bycatchBycatch:
Species caught next to species targeted for fishery. By-catches can consist of non-commercial species and species that are too small, and can be kept (this part is sometimes called by-product) or thrown back into the sea (discards). 
. Any bycatch can immediately be unhooked and released with high survivability.

The management of the tuna stock in the Pacific Ocean is partially effective. There are two [MSC certified] trolling fisheries.
