SIAM So c. 34 (1) :65 ・70 ,1986 RECORD OF AMBICOLORATION IN CYNOGLOSSUS (PISCES : CYNOGLOSSIDAE) FROM THAILAND Thosaporn Thosaporn Wongratana * ABSTRACT An almost ambico10rate “Four- Ii ned tongu e- sole" ,Cynoglossus bilinealus (La cepede) , is is reported from Thailand. It is presumab1y the first record for the genus. Except for most of of the head on the blind side and its.corresponding finrays ,which are pale as in normal specimens ,the body and fins are pigmented. The norma Jl y cycloid scales on the blind side in in the pigmented area are who Jl y replaced by ctenoid scales ,but those on the unpigmented part part on the head are cyc10id. The latera1line sca1es of the pigmented area on the blind side are are cycloid. The pelvic fins are entirely separated from the anal fin by the absence of membrane. membrane. No other major externa1 anomaly is found. PREVIOUS ACCOUNTS Abnormalities Abnormalities in coloration 釘 e more common among members of the order Pleuronectiformes Pleuronectiformes than in any other group of fishes. Other anomalies occasionally in those those fishes are a hooked dorsal fin , incomplete eye migration and side reversa l. Abnormal pigmentation in flatfish is divided into three main types: ambicoloration , albinism ,and xanthochromism (DEVEEN , 1969; COLMAN ,1972 勾).

NORMAN'S (1 934) previous previous explanation of this phenomenon ,later accepted by many authors ,was that “..訓 nbicoloration merely represents variation in the direction of the original bilateral symmetrical symmetrical condition of the ancester of flatfishes." It is also regularly observed that that wholly ambicolorate fishes normally display a higher degree of symmetry than normal normal specimens in pigmentation ,scales , paired fins and final position of the eyes (NORMAN , 1934; COLMAN , 1972). -

(May 2006) Lindsay Ann Glass, B.S., Texas A&M University-Galveston Chair of Advisory Committee: Dr. Jay R. Rooker Several flatfish species including southern flounder (Paralichthys lethostigma) recruit to estuaries during early life. Therefore, the evaluation of estuarine sites and habitats that serve as nurseries is critical to conservation and management efforts. I used biochemical condition and growth measurements in conjunction with catch-density data to evaluate settlement sites used by southern flounder in the Galveston Bay Estuary (GBE). In 2005, beam-trawl collections were made in three major sections of the GBE (East Bay, West Bay, Galveston Bay), and three sites were sampled in each bay. -

Combined Effects of Turbulence and Salinity on Growth, Survival, and Whole-Body Osmolality of Larval Southern Flounder
JOURNAL OF THE Vol. 37, No. 4 WORLD AQUACULTURE SOCIETY December, 2006 Combined Effects of Turbulence and Salinity on Growth, Survival, and Whole-body Osmolality of Larval Southern Flounder ADAM MANGINO JR. AND WADE O. WATANABE1 University of North Carolina Wilmington, Center for Marine Science, 7205 Wrightsville Avenue, Wilmington, North Carolina 28403 USA Abstract The southern flounder (Paralichthys lethostigma) is a commercially important marine flatfish from the southeastern Atlantic and Gulf Coasts of the USA and an attractive candidate for aquaculture. Hatchery methods are relatively well developed for southern flounder; however, knowledge of the optimum environmental conditions for culturing the larval stages is needed to make these technologies more cost effective. The objectives of this study were to determine the effects of water turbulence (as controlled by varying rates of diffused aeration) on growth, survival, and whole-body osmolality of larval southern flounder from hatching through day 16 posthatching (d16ph). Embryos were stocked into black 15-L cylindrical tanks under four turbulence levels (20, 90, 170, and 250 mL/min of diffused aeration) and two salinities (24 and 35 ppt) in a 4 3 2 factorial design. Larvae were provided with enriched s-type rotifers from d2ph at a density of 10 individuals/mL. Temperature was 19 C, light intensity was 390 lx, and photoperiod was 18 L:6 D. Significant (P , 0.05) effects of turbulence on growth (notochord length [NL], wet weight, and dry weight) were observed. On d16ph, NL (mm) increased with decreasing turbulence level and was significantly greater at 20 mL/min (64.2) and 90 mL/min (58.2) than at 170 mL/min (56.3) and 250 mL/min (57.2). -

Key words. - Paralichthyidae - Paralichthys patagonicus - ASW - Argentine coast - Ambicoloration - Head anomalies. A typical anomaly of flatfishes is malpigmentation, which is characterized by either a deficiency of pigment cells on portions of the ocular side (albinism, pesudoalbinism, or hypomelanism), or the presence of dark pigmentation on the normally light-coloured underside of the fish, also called ambicoloration (Bolker and Hill, 2000).

Checklist of the Inland Fishes of Louisiana Abstract Since the publication of Freshwater Fishes of Louisiana (Douglas, 1974) and a revised checklist (Douglas and Jordan, 2002), much has changed regarding knowledge of inland fishes in the state. An updated reference on Louisiana’s inland and coastal fishes is long overdue. Inland waters of Louisiana are home to at least 224 species (165 primarily freshwater, 28 primarily marine, and 31 euryhaline or diadromous) in 45 families. This checklist is based on a compilation of fish collections records in Louisiana from 19 data providers in the Fishnet2 network (www.fishnet2.net). -
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. -
