WELLS SEATTLE, WA June 1975 ATMOSPHERIC ADMINISTRATION / Fisheries Service NOAA TECHNICAL REPORTS National Marine Fisheries Service, Special Scientific Report—Fisheries Series The majnr responsibilities of the National Marine Fisheries Service (NMFS) are to monitor and assess the abundance and geographic distribution of fishery resources, to understand and predict fluctuations in the quantity and distribution of these resources, and to establish levels for optimum use of the resources. NMFS is also charged with the development and implementation of policies for managing national fishing grounds, development and enforcement of domestic fisheries regulations, surveillance of foreign fishing off United States coastal waters, and the development and enforcement of international fishery agreements and policies. NMFS also assists the fishing industry through- marketing service and economic analysis programs, and mortgage insurance and vessel construction subsidies. It collects, analyzes, and publishes statistics on various phases of the industry. The Special Scientific Report—Fisheries series was established in 1949. The series carries reports on scientific investigations that document long-term continuing programs of NMFS. or intensive scientific reports on studies of restricted scope. The reports may deal with applied fishery problems. The series is also used as a medium for the publica- tion of bibliographies of a specialized scientific nature. NOAA Technical Reports NMFS SSRF are available free in limited numbers to governmental agencies, both Federal and State. They are also available in exchange for other scientific and technical publications in the marine sciences. -

Sand Flounder (Family Paralichthyidae) Diversity in North Carolina by the Ncfishes.Com Team
Sand Flounder (Family Paralichthyidae) Diversity in North Carolina By the NCFishes.com Team Along North Carolina’s shore there are four families of flatfish comprising 36 species having eyes on the left side of their body facing upward when lying in or atop the substrate (NCFishes.com; Table 1; Figure 1). The families and species can be confusing to tell apart. The key characteristics provided for in Table 1 should enable one to differentiate between the four families and this document will aid you in the identification of the species in the Family Paralichthyidae in North Carolina. Table 1. The four families of left-facing flounders found along and off the coast of North Carolina. Family Common Name Key Characteristics (adapted from Munroe 2002) No. Species Preopercle exposed, its posterior margin free and visible, not hidden by skin or scales. Dorsal fin long, originating above, lateral to, or anterior to upper eye. Dorsal and anal fins not attached to caudal fin. Both pectoral Paralichthyidae Sand Flounders fins present. Both pelvic fins present, with 5 or 6 rays. 20 Margin of preopercle not free (hidden beneath skin and scales). Pectoral fins absent in adults. Lateral line absent on both sides of body. Cynoglossidae Tonguefishes Dorsal and anal fins joined to caudal fin. No branched caudal-fin rays. 9 Lateral line absent or poorly developed on blind side; lateral line absent below lower eye. Lateral line of eyed side with high arch over pectoral Bothidae Lefteye Flounders fin. Pelvic fin of eyed side on midventral line. 6 Both pelvic fins elongate, placed close to midline and extending forward to urohyal. -

[email protected] 2 Laboratorio de Morfología Funcional Animal, Instituto de Biología, Facultad de Ciencias, Pontificia Universidad Católica de Valparaíso, Av. Brasil 2950, Valparaíso, Chile Abstract.– An osteological description of Hippoglossina macrops, a flounder found in the Southeast Pacific, is presented. Specimens between 11 and 32 cm of total length, captured in the area of Valparaíso and Tomé (Chile) were analyzed. Observations were carried out from dissected specimens previously preserved in formalin and cleared and stained specimens for bone and cartilage. The osteological features of those specimens were then compared to H. montemaris. In general, the Hippoglossina macrops osteology have the features given for the suborder Pleuronectoidei, showing diagnostic characters of Paralichthyidae, such as a supra occipital crest inclined towards the nadiral side; metapterygoid related to the upper edge of the quadrate by cartilage and to the rear end by the hyosimplectic cartilage; subopercle with a subsequent upward extension presenting on their sides not ossified surfaces which give uniformity to the bone; fourth abdominal bone in its portion shows a fusion of the first two anal pterygiophores, are among the most important ones. Within the Paralicthyidae family, H. macrops it shares characteristics with Pseudorhombus and Paralichthys. H. montemaris specimens do not show morphological differences with H. macrops, which questioned the validity of the species. -

PARALICHTHYIDAE Sand Flounders by T.A

Munroe, National Marine Fisheries Service, National Museum of Natural History, Washington D.C., USA iagnostic characters: Most species with eyes on left side of head, reversals frequent in some species D(right-eyed individuals nearly as common as left-eyed in some species occurring outside the Atlantic). No spines present in fins. Mouth protractile, asymmetrical, lower jaw moderately prominent; teeth in jaws some- times canine-like; no teeth on vomer. Preopercle exposed, its posterior margin free and visible, not hid- den by skin or scales. Urinary papilla on ocular side (Paralichthys group) or blind side (Cyclopsetta group), not attached to first anal-fin ray. Dorsal fin long, originating above, lateral to, or anterior to upper eye. Dorsal and anal fins not attached to caudal fin. Both pectoral fins present. Both pelvic fins present, with 5 or 6 rays (6 rays in nearly all species); base of pelvic fin of ocular side on midventral line (Cyclopsetta group), or pelvic fins symmetrically or nearly symmetrically placed on either side of midventral line (base of neither pelvic fin on midventral line) (Paralichthys group). Caudal fin with 17 or 18 rays, 10 to 13 rays branched (usually 11 or 13, rarely 10 or 12).Lateral line present and obvious on both sides of body; lateral line with (Paralichthys group) or without (Cyclopsetta group) high arch over pectoral fin; lateral line present (Paralichthys group) or absent (Cyclopsetta group) below lower eye. Some species of the Cyclopsetta group (some species of Syacium, Citharichthys, and possibly Etropus in this area) show sexual dimorphism in interorbital width, length of the pectoral fin on the ocular side, length of the anterior dorsal-fin rays, and color- ation. -
