They are primarily caught with longlines. Additional types of fishing gear include harpoons, gillnets and trawls. This chart shows how much can safely be eaten each MONTH assuming no other contaminated fish is consumed. The advice is based on EPA guidance and the latest mercury data. More on contaminants ». At recommended level in the Western and Central North Pacific. Reduced to end overfishing in the Eastern Pacific.
Fishing gear used to catch Pacific swordfish rarely contacts the seafloor so habitat impacts are minimal. According to the most recent stock assessments:. The Eastern Pacific Ocean stock is not overfished but is subject to overfishing stock assessment. The Western and Central North Pacific Ocean stock is not overfished and is not subject to overfishing stock assessment.
The annual Billfish Newsletter communicates the results of cooperative efforts between fishery…. North Pacific Swordfish Xiphias gladius. Quick Facts Region. Pacific Islands, West Coast. About the Species U. Population Above target population levels.
Habitat Impacts Fishing gear used to catch Pacific swordfish rarely contacts the seafloor so habitat impacts are minimal. Bycatch Regulations are in place to minimize bycatch. Swordfish have a long, flattened bill that looks like a sword, as their name implies.
They have a stout, rounded body and large eyes. Their first dorsal fin is tall and crescent-shaped. The second is much smaller. Their anal fins are similar in shape to the dorsal fins but smaller. They have a broad, crescent-shaped tail. Their color is darkest on top, generally black or brown. Adult swordfish have no teeth or scales. Swordfish are one of the fastest and largest predators in the ocean. There are some concerns that fishing pressure in both the Pacific and Indian Oceans is set too high, which could lead to overfished stocks in future.
Video monitoring of fishing boats operating in the tuna fisheries is a welcome advance, improving confidence in fishery log book reports. Swordfish are caught on longlines that also catch endangered wildlife, such as turtles, seabirds, whales and dolphins. Reported interactions with turtles, seabirds, whales and dolphins have increased significantly in recent years, particularly in the larger eastern fishery, most likely as a result of the introduction of video monitoring in this fishery.
The number of threatened and protected wildlife caught in the fishery is of increasing concern, and fishery managers would need to put wildlife protection measures in place to retain an Amber rating in future. Say No. Swordfish are generally taken as byproduct in longline fisheries targeting species of tuna. Bycatch of vulnerable marine wildlife is generally not monitored, but the impact of longlining on many shark species has been well-documented.
Population declines of sharks as a result of bycatch on tuna longlines is of major concern, particularly as sharks are sometimes targeted for their high value fins. Shark finning cutting the fins off dead sharks and throwing the body overboard is still legal in NZ, although bans are expected to be phased in. More information Imported from fisheries in the Pacific Ocean t Swordfish is a highly migratory species, fished throughout its range in the Pacific, Indian and Atlantic Oceans and in the Mediterranean Sea.

They have a broad, crescent-shaped tail. Their color is darkest on top, generally black or brown, and fades to a lighter color below.
Atlantic swordfish are one of the fastest predators in the ocean. Their streamlined body allows them to swim at high speeds, up to 50 mph. They grow quickly and reach a maximum size of about 1, pounds. However, the average size caught in the fishery is 50 to pounds. Swordfish live about 9 years. Females are able to reproduce between 4 and 5 years of age. Depending on their size, females can produce anywhere from 1 million to 29 million eggs.
They spawn multiple times throughout the year in warm tropical and sub-tropical waters. Swordfish feed on a variety of fish and invertebrates such as squid. They capture prey by slashing their bill back and forth, stunning or injuring prey in the process. They have developed unique characteristics, such as a special eye muscles and a heat exchange system that allows them to swim in deep, cold water in search of prey.
Swordfish feed at the top of the food chain and are rarely preyed on by other animals.
