Typically, pink shrimp average more than count per pound, compared to for the larger P. Almost all Pacific pink shrimp are cooked and peeled and sold fresh or frozen. While about a dozen species of commercially fished coldwater shrimp belong to the Pandalidae family, l arger shrimp are preferable and more expensive. Pink shrimp are medium-sized and live between three and five years. They are protandric hermaphrodites, beginning life as males and later becoming females. Juveniles mature and breed as males during their first year, and later become and breed as females for the following years.
The proportion of shrimp that change sex varies from year to year. High fishing pressures or naturally high mortality rates can induce males to change into females at a younger age, or even completely skip the male stage. Mating takes place in the fall when females produce up to eggs, which are internally fertilized. The female carries them under her abdomen for about six days before the eggs develop into planktotrophic larvae, which hatch in the spring.
They remain as plankton for four to six months, drifting with the currents. Pink shrimp are smaller than most tropical shrimp, growing up to 6.
Growth rates vary by region, sex, age, and timing of gender transition — females tend to grow larger than males. Because they reside primarily in deep water, cold water shrimp do not ingest mud or sand, giving them clearer veins than those of warm water shrimp.
They also have a longer rostrum, and claws on one pair of feet instead of three. Their prey consists primarily of smaller planktonic animals, but adults may also feed on marine worms, small crustaceans, sponges, and dead animals. They are prey to many fish species including hake, arrowtooth flounder, sablefish, petrale sole, rockfish, and skates. They generally occur at depths from to feet 45 to meters. High densities of pink shrimp occur in well-defined areas, known as beds, over green mud or mud-sand substrates.
Spawning occurs throughout their range; however, the majority of commercial quantities occur between Queen Charlotte Sound, British Columbia and Point Arguello, California.
Pink shrimp undergo diel vertical migration, inhabiting deeper waters during the day and moving to shallower waters at night to feed. After conducting the study, they formulated a list of research needs including: continued investigation of shrimp population dynamics in relation to fishing and the environment; develop methods to monitor and further reduce non-target catch; and improve their understanding of ecosystem effects of the fishery and develop methods to reduce impacts.
A study published in Fisheries Oceanography off southern Oregon suggests that poor shrimp recruitment in and in that area may be due to a northward shift in weather conditions, leading to strong spring and summer upwelling winds. Upwelling of deep-ocean water provides nutrients to coastal ecosystems, but also results in offshore transport of surface waters and pelagic larvae; such as recently hatched ocean shrimp. This raises the possibility that shrimp recruitment, especially in southern Oregon, may become more variable in the future, underscoring the need to maintain consistent fishery monitoring and sampling.
While the plan has never been formally adopted, California, Oregon, and Washington have several uniform management regulations and formally work together with the PFMC to manage the fishery. Among the uniform measures the state agencies have agreed upon are:.
Some federal regulations do apply to the pink shrimp trawl fishery along the US West Coast. Additionally, the pink shrimp fishery is subject to federal regulations outlined in the West Coast Groundfish Fishery Management Plan to protect groundfish stocks and essential fish habitat. The Oregon and Washington as well as part of California pink shrimp fisheries are limited entry with the number of available fishing permits varying by state.
Recently the number of active fishers has been less than the number of available commercial licenses. Pink shrimp currently account for the majority of the landings and revenue from the US West Coast shrimp fisheries — with the majority of landings occurring in Oregon. Oregon currently carries out stock assessments for pink shrimp while California and Washington do not.
While the shrimp fishery is dominated by pink shrimp, other northern shrimp species are caught as part of the multispecies nature of fishery. Among other measures the DFO uses to manage the shrimp fishery include:. The pink shrimp fishery along the West Coast lacks population abundance estimates, but the population is assumed to be stable and not overfished. Stocks in Newfoundland appear to be healthy.
The primary gear used to catch pink shrimp are trawls. Pink shrimp live in muddy habitats, which also lessens the gear impact. A very small number of pink shrimp fishermen use traps and pots. Bycatch in this fishery is very low, consisting mostly of smelt, flatfish, and rockfish. Bycatch reduction devices are mandatory and a Nordmore grate, which fits into the trawl, has greatly reduced Pacific rockfish bycatch. Each state on the West Coast has its own regulations concerning pink shrimp.
Although there are substantial management measures in place, there is inadequate stock monitoring. An individual fishing quota system for the Pacific Coast groundfish trawl fishery was finalized in January However, pink shrimpers expressed concern that the quotas would force additional trawlers into their fishery, which lacks the processing infrastructure to handle an increased fleet size.

Why are scientists concerned about Asian tiger shrimp in East Coast waters?
Section Navigation Section Navigation. Printer friendly. Northern shrimp are medium-sized shrimp with a rather slender body. They have a uniform pink color with no banding. The rostrum a horn-like projection between the eyes is 1. The third abdominal segment, at the bend in the abdomen, has a distinctive dorsal spine. There are also single spines on the rear margin of the third and fourth abdominal segments. In the Pacific Ocean, northern shrimp are also called pink shrimp, northern pink shrimp, Alaska pink shrimp, or spiny shrimp.
Until recently, they were considered the same species as the pink shrimp, Pandalus borealis , found in the north Atlantic. The Pacific population was reclassified as P. However, some taxonomists consider the Pacific population to be a subspecies, P. For this reason, the scientific name P. The most similar species to northern shrimp is the ocean shrimp, or ocean pink shrimp P.
The ocean shrimp has similar coloration but can be distinguished from northern shrimp because it lacks the sharp dorsal spine on the third abdominal segment. Northern shrimp larvae hatch in the spring and swim throughout the water column for most of the first summer. They molt as they grow, shedding their outgrown external skeletons and growing new, larger ones.
By the end of the summer, the larvae settle to the bottom and begin the juvenile phase. During the second summer, they molt again and become sexually mature, typically as males.
After breeding at least one or two times as a male, they gradually transform permanently into females. The transition to female usually occurs in their fourth year of life and takes most of the summer. A very small proportion of northern shrimp start out as females and stay female throughout life.
Northern shrimp breed in the fall, after the females molt and become ready for breeding. A male grasps a female and deposits a packet of sperm on underside of her abdomen. The eggs are released by the female and fertilized as they pass over the sperm packet. The fertilized eggs embryos then stick to the hair-like structures on the female's pleopods swimmerettes of the female.
Here the embryos develop over the winter, protected by the overhanging abdominal plates. When the embryos are ready to hatch the following spring, the female rests on the bottom and fans water under her abdomen to disperse the hatched larvae.
Females may hatch up to 4, eggs, but the average is about half that. Growth of northern shrimp is relatively fast at first, and then slows as they get older. Females with eggs do not molt while carrying eggs. Northern shrimp may live for a maximum of at least 5 or 6 years in the Gulf of Alaska.
Age is typically estimated based on modes, or clusters, in the distributions of length measurements. Unlike their heavy-bodied cousins the spot shrimp P. When targeting plankton, northern shrimp filter feed, capturing their prey by trapping it among their legs. During the day however, they typically forage in the bottom sediments on worms, small crustaceans, algae, and detritus dead organic matter.
Several researchers have found that the abundance of northern shrimp is correlated with the organic content of bottom sediments. Fish species that prey upon northern shrimp include sablefish, arrowtooth flounder, Pacific cod, walleye pollock, rockfish, halibut, salmon, spiny dogfish, and many others.
Northern shrimp are also consumed by common murres and other seabirds. Northern shrimp move up in the water column at night to feed, except that females carrying eggs remain near the bottom. There may also be some seasonal movements to shallower or deeper water. For example, egg-bearing females in some areas have been documented to move into shallower water when hatching larvae.
Larvae may be distributed over larger areas by strong currents, but no large movements of adults have been documented. In the Pacific Ocean, northern shrimp are found from the Bering Sea south to Oregon in the east, and south to Japan and Korea in the west. Northern shrimp are also found in the north Atlantic, but these may be a separate species or subspecies.
Northern shrimp are typically found over soft mud or silt bottoms in m of water, but have been found at depths of up to 1, m 4, ft. Northern shrimp populations in the western and central Gulf of Alaska plummeted during the late s and early s.
Although harvests were high and may not have been sustainable in some areas, declines in abundance in both fished and unfished areas suggest that fishing played a limited role in the population collapse. The decline was generally attributed to a climate regime shift beginning in , which caused significant warming of Gulf of Alaska waters. Warming is believed to have direct effects on shrimp reproduction success and favors production of fishes that prey on shrimp.
Northern shrimp abundance remains low over the western and central Gulf of Alaska, and the historically important trawl fisheries for northern shrimp remain closed.
Recent trawl survey estimates in the Kodiak Archipelago and south of the Alaska Peninsula areas have been substantially below the thresholds for allowing harvest in nearly all areas surveyed. Trawl surveys in Kachemak Bay and along the outer Kenai Peninsula continue to show low abundance of northern shrimp. Status in the Bering Sea is unknown due to a lack of surveys, but abundance is believed to be low when compared to previous levels.
In contrast, northern shrimp stocks in Southeast Alaska do not appear to have been affected by the regime shift. Following the decline in northern shrimp populations and in the shrimp market, the remaining trawl fisheries in the state began to target the larger sidestripe shrimp, Pandalopsis dispar. Available information indicates that surveyed stocks outside of Southeast Alaska remain at low abundance, with no evidence of significant improvement in the near future. The primary factors that can threaten northern shrimp populations are ocean regime shifts caused by climate cycles, ocean acidification, and overfishing.
Regime shifts are changes in climate-ocean ecosystems from one relatively stable state to another, usually as the result of cyclic or periodic changes in climatic conditions. In the North Pacific, cool regimes tend to benefit shrimp, crabs, and forage fish, while warm regimes tend to benefit cod, pollock, halibut, salmon, and other fishes.
Due to their narrow temperature tolerance, northern shrimp may be particularly sensitive to increases in ocean temperature. Ocean acidification is a potential threat to shrimp and many other invertebrates.
The ocean absorbs carbon dioxide from the atmosphere. Carbon dioxide levels in the atmosphere are increasing from changes in land use and the burning of fossil fuels. As carbon dioxide builds up in the atmosphere, more is dissolved in seawater. This makes the ocean more acidic, which reduces the amount of calcium carbonate available for shell-building organisms such as shrimp, crabs, corals, etc.
The effects of ocean acidification are projected to be larger and happen sooner at higher latitudes. Overfishing occurs when fishery removals exceed the production by the remaining stock. Although overfishing may have occurred in the past in some areas, northern shrimp are now taken mostly as bycatch in small amounts that are unlikely to result in overfishing.
