The properly has a serrated edge and the serrations at its angle are enlarged, where there is also often a spine bent upwards, clothed in skin and located on its lower edge immediately in front of its angle. The upper edge of the gill cover is notably convex.

The membranes between the dorsal fin spines have deep notches. The caudal fin has a rear margin which is convex in juveniles of standard lengths less than 30 centimeters (12 in) and is straight or concave in adults.

The overall color is dark brown with a black margin to the spiny part of the dorsal fin. Juveniles are dark brown and are marked with obvious white spots arranged in vertical rows on the rear part of the head and on the body.

The upper part of the base of the caudal fin has a deep black saddle-like mark that extends underneath the lateral line. This species attains a maximum published total length of 122 centimeters (48 in), although are more commonly around 60 centimeters (24 in), and a maximum published weight of 30 kilograms (66 lb).

The snowy grouper is found at depths of between 10 and 525 meters (33 and 1,722 ft) over rock substrates in offshore waters, although they are commonest between 100 and 200 meters (330 and 660 ft). Like most groupers this species is predatory and prey items recorded for adults include fishes, gastropods, cephalopods, and brachyuran crustaceans.

They are protogynous hermaphrodites and form aggregations for spawning. Females attain sexual maturity at ages between 3 and 5 years old and total lengths of 45.1 to 57.5 centimeters (17.8 to 22.6 in), changing to males 3 to 4 years after attaining sexual maturity as females.

Off North America this species spawns from May to June and a female may lay more than 2 million eggs in a season. The snowy grouper is targeted by commercial fisheries in the United States, in Central America and off South America using hook-and-line, bottom longlines, traps and trawls.

In United States waters the snowy grouper may be fished for from 1 January to 31 August but as its management includes an annual catch limit, the fishery may be closed if the limit has been met or is projected to be met. ^ a b c d Free, Trainer and Paul, Daniel, eds.

Range & Habitat : Western Atlantic: Massachusetts, USA to southern Brazil, includes the Gulf of Mexico and the Caribbean. Snowy groupers can be found in the outer continental shelf of the South Atlantic Bight, which is characterized by ridges, terraces and precipitous cliffs.

The species is distributed in the western Atlantic from Massachusetts to Brazil, including the Gulf of Mexico, the Lesser Antilles and the northern coast of Cuba. Identification & Biology: SnowyGrouper earmark gray all over, the snowy groupers name derives from the obscure white spots arranged in a definite geometric pattern over the body.

Smaller fish are dark brown overall, punctuated with coin-size pearly white spots on the sides. A distinctive black, saddle-shaped blotch occurs on the caudal peduncle and extends down below the lateral line.

Larger snowy groupers usually lose the white spots and caudal saddle and become dark brown with a slight coppery tint. Market Description: Like most groupers, it has a very lean white flaky flesh and is versatile in cooking.

The commercial harvest of snowy grouper in federal waters of the South Atlantic will close at 12:01 a.m., local time, on December 12, 2020. During the commercial closure, all sale or purchase of snowy grouper is prohibited, and harvest or possession of snowy grouper in or from federal waters is limited to the recreational bag and possession limits while the recreational sector is open.

The 2020 July through December commercial catch limit is 46,181 pounds gutted weight. According to the accountability measure, commercial harvest must close to prevent the catch limit from being exceeded.

Differs from marbled grouper by a more slender body, pelvic fin about equal to or slightly longer than pectoral, and scales rough to the touch; also fins lined in white; differs from the Warsaw grouper by having a less steep mouth angle and the maxilla (upper jaw) extends past the eye (does not in Warsaw). The SnowyGrouper, also known as the Brownie, chocolate or golden grouper is named for the white spots that are geometrically placed on their bodies.

This tropical species lives in the outer continental shelf in water 600 to 1,000 feet deep. Their color is dark gray or brown with scattered whitish spots.

Snowy grouper, Epimetheus hiatus, also known as Golden Grouper, is deep water fish distributed throughout Florida and the Western Bahamas, in the western Atlantic from Massachusetts to Brazil, including the Gulf of Mexico, Bermuda, Caribbean, the Lesser Antilles, Bimini and the northern coast of Cuba. Coloration is extremely pleasant, with basically darker purple or brown hues comprising a background highlighted by white dots that look like snowflakes fallen on an antique Oldsmobile.

Adults retain black or dark brown bodies, but with lighter marks on the tail and caudal fins. Rear margin of caudal fin convex in juveniles (5 to 30 cm standard length), straight or concave in adults.

Smaller fish are dark brown overall, punctuated with coin-size pearly white spots on the sides in vertical series usually extending onto head and dorsal fin. Adults are dark brown, with margin of spinors dorsal fin black.

A distinctive black, saddle-shaped blotch occurs on the caudal peduncle and extends down below the lateral line. Larger snowy groupers usually lose the white spots and caudal saddle and become dark brown with a slight coppery tint.

The eastern Pacific species Star-studded grouper is very similar to SnowyGrouper ; juvenile Star-studded grouper (5 to 10 cm standard length) have smaller eyes, pelvic fins not longer than pectoral fins, and more pectoral-fin rays (morally 19). Habitats Sometimes called the chocolate or golden grouper, the snowy is a fish of deep water with adults living in the outer continental shelf in water 600 to 1,000 feet deep.

Snowy groupers can be found in the outer continental shelf of the South Atlantic Bight, which is characterized by ridges, terraces and precipitous cliffs. These fish are usually found offshore in depths of at least 400 feet, and they are not commonly encountered by anglers.

These fish are found primarily in marine environments, but can also occur in brackish and freshwater areas. SpawningSnowygrouper are protogynous hermaphrodites, spawning from April to July and producing more than 2 million eggs.

Mating rites are assumed to involve one male and a harem of females, followed by a seasonal run up the water column, where millions of eggs are fertilized. Snowy groupers are eager to strike; they could be caught with hook-and-line, bottom longlines, and traps.

Finding one and hooking it is difficult enough, and it can take a long time to pull it to the surface. The extra lean white meat is firm and moist with large flake and a sweet, mild flavor.

Actual cooking time will depend on the thickness of the fish and the temperature of the oil. Info Summary ROV and submersible video footage recorded in 1985, 2002, and 2010 from hard bottom habitat known as the Georgetown Hole or Charleston Lumps located NE of Charleston, SC in depths ranging from 175 to 300 m were reviewed to assess temporal trends in reversal fish abundance and bottom habitat preferences for key species.

The main purpose of this long-term assessment of deep reef fish abundance and bottom habitat associations was to determine if deep reef fish populations have recovered since the development and implementation of the snapper/ grouper fishery management plan (1983) and its various amendments. Blue line Tile fish were found in the highest densities within low relief areas (5 fish/1000 m3) and mixed hard/soft bottom regions (6 fish/1000m3).

Abundance of SnowyGrouper and Blue line Tile fish have both increased from 1985 to 2010 predominantly within low relief bottom regions where they have significantly lowered prey populations of Yellow fin Bass and restored a balanced deep reef ecosystem. Smaller fish are dark brown overall, punctuated with coin-size pearly white spots on the sides.

A distinctive black, saddle-shaped blotch occurs on the caudal peduncle and extends down below the lateral line. Larger snowy groupers usually lose the white spots and caudal saddle and become dark brown with a slight coppery tint.

Snowy grouper are protogynous hermaphrodites, spawning from May to June and releasing more than 2 million eggs. Open Season: May 1 – August 31 Note: since this species is managed under an Annual Catch Limit, the fishery could close if the recreational Annual Catch Limit is met or projected to be met.

If an in-season closure were to be announced by NOAA Fisheries, all relevant information will be included here. Recreational and commercial fishermen are required to use hooking tools when fishing for snapper grouper species.

At least one hooking device is required and must be used as needed to remove hooks embedded in South Atlantic snapper- grouper with minimum damage. Definition of a Descending Device: an instrument to which is attached a minimum of a 16 ounce weight and a length of line that will release the fish at the depth from which the fish was caught or a minimum of 60 feet.

Since minimizing surface time is critical to increasing survival, descending devices shall be readily available for use while engaged in fishing. The use of non-stainless steel hooks when fishing for snapper- grouper species with hook-and-line gear and natural baits south of 28º north latitude.

Bottom longline is allowed only in depths 50 fathoms or more and only north of St. Lucie Inlet, Florida. Recreational and commercial fishermen are required to use hooking tools when fishing for snapper grouper species.

A circle hook is defined as a fishing hook designed and manufactured so that the point is turned perpendicularly back to the shank to form a generally circular, or oval, shape.

Identifying Characteristics: The western snowy plover is a small shorebird, about 6 inches long, with a thin dark bill, pale brown to gray upper parts, white or buff colored belly, and darker patches on its shoulders and head, white forehead and super cilium (eyebrow line). Juvenile and basic (winter) plumage are similar to adult, but the black patches are absent.

Some breeding males, especially in the southern portion of the species’ range, may exhibit a rusty or tawny cap. Their dark gray to black legs are a useful characteristic when comparing them to other plover species (Page et al. 1995).

Current Geographic Range: The Pacific coast population of the snowy plover is defined as those individuals that nest adjacent to tidal waters of the Pacific Ocean, and includes all nesting birds on the mainland coast, peninsulas, offshore islands, adjacent bays, estuaries, and coastal rivers (USDA Fish and Wildlife Service 2004). The current known breeding range of this population extends from Damon Point, Washington, to Bahia Magdalena, Baja California, Mexico (USDA Fish and Wildlife Service 2006).

Snowy plovers that nest at inland sites are not considered part of the Pacific coast population, although they may migrate to coastal areas during winter months. Life History: Pacific coast plovers typically forage for small invertebrates in wet or dry beach-sand, among tide-cast kelp, and within low fore dune vegetation (USDA Fish and Wildlife Service 2004).

The breeding season in the United States extends from March 1 through September 30, although courtship activities have been observed during February. Pacific coast snowy plovers are polyandrous (i.e., a female may breed with more than one male), and share incubation duties.

Females typically desert the brood shortly after hatching, leaving the chick rearing duties to the male. Snowy plover chicks are precocity, leaving the nest within hours after hatching to search for food.

Suitable nesting habitat is distributed throughout the listed range, but may be widely separated by areas of rocky shoreline. Population and Habitat Status: Historical records indicate that nesting western snowy plovers were once more widely distributed in coastal California, Oregon, and Washington.

In Washington, snowy plovers formerly nested at five coastal locations (USDA Fish and Wildlife Service 2006). In Oregon, snowy plovers historically nested at 29 locations on the coast (USDA Fish and Wildlife Service 2006).

Currently, there are only 10 nesting locations, representing a 65 percent decline in active breeding areas. Reproductive success in Recovery Unit 2 during this time period has ranged from 0.8 to 1.7 fledglings per adult male (Cowell et al. 2005).

Threats: Poor reproductive success, resulting from human disturbance, predation, and inclement weather, combined with permanent or long-term loss of nesting habitat to encroachment of non-native European beach grass (Ammonia aren aria) and urban development has lead to a decline in active nesting, as well as an overall decline in the breeding and wintering population of the snowy plover along the Pacific coast (USDA Fish and Wildlife Service 1993). Human activities, such as walking, jogging, running pets, horseback riding, and vehicle use, are key factors in the ongoing decline in breeding sites and populations.
