Once considered an undesirable fish, the Pacific Grenadier has gained some acceptance in the domestic market but is usually not targeted by fisheries. 
- Has a large head and eyes with a long body that tapers to a point. It averages 46-65 cm (18-26 inches) in length and has a small chin barbel. It has a short, pointed snout. 
- Gray to grayish brown when young, and turns a dark brown color in adulthood. 
- Has a large gas bladder that expands and is usually everted when hauled to the surface. 
- Found in deep waters ranging 300-3,700m deep off coasts all along the North Pacific, from northern Japan to the Bering seas and as far south as northern Mexico. 
- Far-ranging scavenger that typically feeds on decaying material and other benthic organisms like small fish, krill, prawns, amphipods, and cephalopods. [1,2]
- Spawning occurs throughout the year, but in coasts off southern California spawning peaks between late winter and early summer. Further north off Point Conception, heaviest spawning may occur earlier. 
- The Pacific Grenadier expends energy very slowly and takes a long time to grow and reproduce. 
- Spends its life on the sea floor, scavenging for food. Grenadier have even been observed in extreme low-oxygen environments that would be deadly for other fishes! [1,5]
- Capable of traveling long distances while scavenging. One was even found far away from its typical range in the South Atlantic! [2,6]
- Seasonal availability for recreational fishing depends on the regional management authority. Refer to your local management area's rules to see when fishing for Pacific Grenadier is allowed. 
- Landed commercially throughout the year, but landings tend to decrease during July to September. 
Regulatory and managing authority
- Managed federally by the NOAA fisheries and, as established by the Magnuson-Stevens Act, the Pacific Fishery Management Council (PFMC) through the Pacific Coast Groundfish Fishery Management Plan (FMP), where it is listed as an Ecosystem Component Species. 
- As established by the Marine Life Management Act, the California Fish and Game Commission (CFGC) regulates the fishery in state waters, and the California Department of Fish and Wildlife (CDFW) manages this fishery. [22,23]
- The California Groundfish Collective combines input from the industry and government entities to inform regulatory and management measures for this fishery. 
- Most grenadier is caught by groundfish fisheries, especially in trawl and non-sablefish endorsed longline fisheries. 
- A variety of gear is used including bottom trawl, longline, pot, and hook and line, but trawl is the most common. 
Status of fishery
- Usually caught as bycatch by fisheries targeting other species, and is typically discarded. Most Pacific Grenadier is consumed domestically. 
- Considered a 'Good Alternative' by Seafood Watch. 
- Although stocks have not been fully assessed, fishing mortality is very low relative to overfishing limits. 
Potential ecosystem impacts
- The use of bottom-tending gear like trawls has the potential to seriously damage seafloor habitat. 
- There is concern that this species is vulnerable to overfishing due to its low fecundity and slow growth. 
- Typically only the filet is consumed. 
Description of meat
- Filets are light pink when raw. When cooked, it turns white, has a mild and slightly sweet taste and a firm, flaky texture. [9,19]
- Grenadier can be fried, baked, roasted or broiled. 
- In Japan, this fish is sometimes used for surimi, which is used to make imitation crab sticks and other fish cake products.

Nutritional informaton provided is based on information for blue grenadier, a similar fish. 
There is some concern about mercury levels in grenadier as a deep-sea fish, but more studies are needed to understand the impact of mercury in this fish. [13,14]
- Available year-round in California.
