FAO Names: En - Red hind; Fr - Mérou couronné; Sp - Mero colorado. Diagnostic characters: Body depth distinctly less than head length, 2.7 to 3.1 in standard length (for fish 17 to 38 cm standard length). Gill rakers on first arch 8 or 9 on upper limb and 16 to 18 on lower limb, total 24 to 26. Dorsal fin with 11 spines and 15 or 16 soft rays, the third or fourth spine longest, the interspinous mem- branes incised and produced into a short flag behind tip of each spine; anal fin with 3 spines and 8 soft rays; pectoral-fin rays 16 to 18; rear edge of caudal fin convex. Preopercle rounded, evenly serrate; rear nostril larger than front nostril. Scales ctenoid, lateral scale series 92 to 104. Colour: ground colour buff, greenish white, or pale reddish brown, the head and body covered with bright red spots which be- come reddish brown dorsally; spinous dorsal fin olive, with yellow flags at tips of spines; soft dorsal, caudal, and anal fins olivaceous, with a broad blackish submarginal band and narrow pale edge; pectoral fins pale or- ange-red with darker red spots on base; pelvic fins coloured like body but darker distally and along leading edge. Size: Maximum 76 cm; maximum weight 8.3 kg. Habitat, biology, and fisheries: Shallow reefs and rocky bottoms in depths of 2 to 100 m. Red hind feed mainly on crabs (40%) and fishes (21%). Females mature at 22 to 24 cm total length, and change sex at 28 to 38 cm total length.On the outer reef in 20 m off the south coast of Puerto Rico, spawning of fish in aggregations occurred during the full moon in January and February. Ripe females were recognized by their swollen abdo- mens and colour pattern of dark spots on a white background; males displayed a darker mottled pattern, with an area of dark vertical bars or squares on the body above the anal fin. Females rested on or close to the bot- tom, while males patrolled an area that included 1 to 5 females and defended this territory from other males. On 2 occasions, spawning was initiated by a female swimming about 0.5 m up off the bottom and being joined by a male; gametes were released without any upward rush or rapid movement. In one case, another female joined the pair above the bottom and spawned with them. The transparent eggs are buoyant and usually con- tain a single oil globule. For larvae reared in the laboratory, hatching occurred 27 h after fertilization at 26.5° C; mortality increased greatly after 6 to 7 days, and no larva survived through metamorphosis. Fecundity varies from 90 000 eggs for a 26 cm (total length) fish to over 3 million eggs in a 45 cm (total length) fe- male. Although not as large as some other groupers, it is the most important species in the Caribbean grouper fishery. Caught with hook-and-line, traps, and spears. Distribution: Bermuda, North Carolina to Brazil, including Gulf of Mexico and the West In- dies. Remarks: In the West Indies, the red hind is also called ‘cabrilla morja’ or ‘strawberry grouper’; in Venezuela, it is known as ‘tofia’. Perciformes: Percoidei: Serranidae 1343 Epinephelus itajara (Lichtenstein, 1822) EET Frequent synonyms / misidentifications: Promicrops itajara (Lichtenstein, 1822) / None. FAO names: En - Goliath grouper (AFS: Jewfish); Fr - Mérou géant; Sp - Mero guasa. Diagnostic characters: Body robust, oblong, the greatest width equals half or more of body depth, which is less than head length (in fish 15 to 160 cm). Head extremely broad; interorbital flat and very wide, its width equals eye diameter in fish 10 to 15 cm standard length, is distinctly greater than eye diameter in fish 18 to 30 cm standard length, and 2 to 5 times greater than eye diameter in fish 30 to 160 cm standard length.

    SEDAR 15-RD07 Final Report Characterization of commercial reef fish catch and bycatch off the southeast coast of the United States. CRP Grant No. NA03NMF4540416 Funding amount: $100,000 Federal $4,130 Match Patrick J. Harris and Jessica Stephen Marine Resources Research Institute South Carolina Department of Natural Resources 217 Fort Johnson Road P.O. Box 12559 Charleston, SC 29412 I. Characterization of commercial reef fish catch and bycatch off the southeast coast of the United States. Patrick J. Harris, South Carolina Department of Natural Resources, Charleston, SC 29412. Grant Number: NA03NMF4540416 July 2005. II. Abstract There is clearly a need to characterize the entire catch of commercial fishermen and compare differences in abundance and species diversity to what is caught in fishery-independent gear. As we move towards a multi-species management approach, these types of data are essential. In addition, estimates of release mortality are needed for stock assessments but currently this is not being measured for fishery-dependent data. Many reef fishes captured at depths greater than ~ 20 m often have problems submerging when released by commercial fishermen. The goal of the research project was to characterize the entire (retained and discarded) catch of reef fishes from a selected commercial fisherman including total catch composition and disposition of fishes that were released. During April- November 2004, Captain Mark Marhefka dedicated one fishing trip (5-7 day duration) each month to the collection of fishery-dependent data. Date, location and collection number were recorded for each site fished by Captain Marhefka using a PDA equipped with a GPS.

  • Diet Composition of Juvenile Black Grouper (Mycteroperca Bonaci) from Coastal Nursery Areas of the Yucatán Peninsula, Mexico
    BULLETIN OF MARINE SCIENCE, 77(3): 441–452, 2005 NOTE DIET COMPOSITION OF JUVENILE BLACK GROUPER (MYCTEROPERCA BONACI) FROM COASTAL NURSERY AREAS OF THE YUCATÁN PENINSULA, MEXICO Thierry Brulé, Enrique Puerto-Novelo, Esperanza Pérez-Díaz, and Ximena Renán-Galindo Groupers (Epinephelinae, Epinephelini) are top-level predators that influence the trophic web of coral reef ecosystems (Parrish, 1987; Heemstra and Randall, 1993; Sluka et al., 2001). They are demersal mesocarnivores and stalk and ambush preda- tors that sit and wait for larger moving prey such as fish and mobile invertebrates (Cailliet et al., 1986). Groupers contribute to the ecological balance of complex tropi- cal hard-bottom communities (Sluka et al., 1994), and thus large changes in their populations may significantly alter other community components (Parrish, 1987). The black grouper (Mycteroperca bonaci Poey, 1860) is an important commercial and recreational fin fish resource in the western Atlantic region (Bullock and Smith, 1991; Heemstra and Randall, 1993). The southern Gulf of Mexico grouper fishery is currently considered to be deteriorated and M. bonaci, along with red grouper (Epinephelus morio Valenciennes, 1828) and gag (Mycteroperca microlepis Goode and Bean, 1880), is one of the most heavily exploited fish species in this region (Co- lás-Marrufo et al., 1998; SEMARNAP, 2000). Currently, M. bonaci is considered a threatened species (Morris et al., 2000; IUCN, 2003) and has been classified as vul- nerable in U.S. waters because male biomass in the Atlantic dropped from 20% in 1982 to 6% in 1995 (Musick et al., 2000). The black grouper is usually found on irregular bottoms such as coral reefs, drop- off walls, and rocky ledges, at depths from 10 to 100 m (Roe, 1977; Manooch and Mason, 1987; Bullock and Smith, 1991; Heemstra and Randall, 1993).

  • Type Species, Perca Rogaa Forsskål, 1775, by Original Designation and Monotypy; Proposed As a Subgenus
    click for previous page 16 FAO Species Catalogue Vol. 16 2.4 Information by genus and species Aethaloperca Fowler, 1904 SERRAN Aethal Aethafoperca Fowler, 1904:522; type species, Perca rogaa Forsskål, 1775, by original designation and monotypy; proposed as a subgenus. Synonyms: None. Species: A single species widely distributed in the Red Sea and Indo-West Pacific region. Remarks: The genus Aethaloperca is closely related to Cephalopholis and Gracila which also have IX dorsal-fin spines and several trisegmental pterygiophores in the dorsal and anal fin. Smith-Vaniz et al. (1988) discussed the relationships of these genera, and we agree with their decision to recognize Aethaloperca as a valid genus. It differs from Cephalopholis and Gracila in the configuration of the pectoral and median fins and in some cranial features (the anteriorly converging parietal crests and the well-developed median crest on the frontals that extends to the rear edge of the ethmoidal depression). Aethaloperca also differs from Gracila in the shape of the maxilla and in having a larger head and deeper body. Aethaloperca rogaa (Forsskål, 1775) Fig. 35; PI.

In extreme cases, when fishing pressure is high, aggregations can dwindle and even cease to form, sometimes within just a few years. Whether or not they will recover and what the long-term effects on the fish population(s) might be of such declines are not yet known. We do know, however, that healthy aggregations tend to be associated with healthy fisheries. It is, therefore, important to understand and better protect this critical part of the life cycle of aggregating species to ensure that they continue to yield food and support livelihoods. Why a Handbook? As fishing technology improved in the second half of the twentieth century, engines came to replace sails and oars, the cash economy developed rapidly, and human populations and demand for seafood grew, the pressures on reef fishes for food, and especially for money, increased enormously.

This notice is submitted on behalf of the Center for Biological Diversity, WildEarth Guardians, and Miami Waterkeeper. Specifically, the Service has failed to designate critical habitat for Nassau grouper (Epinephelus striatus). Id. §§ 1533(a)(3)(A), 1533(b)(6)(C). The Service’s failure deprives the grouper important protections and puts it at further risk of extinction. This letter is provided pursuant to the 60-day notice requirement of the citizen suit provision of the Act, to the extent that such notice is deemed necessary by a court. Id. § 1540(g). A. The ESA Requires the Service to Designate Critical Habitat for Nassau Grouper In enacting the ESA, Congress recognized that certain species “have been so depleted in numbers that they are in danger of or threatened with extinction.” Id. § 1531(a)(2).

Snapper and grouper are important fishery resources with great commercial value for exporters to major international markets. The fisheries also support the livelihoods and food security of many local, small-scale fishing communities worldwide. It is therefore all the more critical that management of these fisheries improves, thus ensuring this important resource will remain available to provide both food and income. Landings of snapper and grouper have been steadily increasing: in the 1950s, total landings were about 50,000 tonnes, but they had grown to more than 612,000 tonnes by 2013.
