Scophthalmus Rafinesque, 1810: The valid generic name for the turbot, S. maximus (Linnaeus, 1758) [Pleuronectiformes: Scophthalmidae] by Nicolas BAILLY* (1) & Bruno CHANET (2) ABSTRACT. - In the past 50 years, the turbot is referred to either as Scophthalmus maximus (Linnaeus, 1758) or Psetta maxima (Linnaeus, 1758) in the literature. Norman (1931) had argued that the valid name for the turbot was Scophthalmus maximus. However, his recommendation was never universally accepted, and today the confusing situation exists where two generic names are still being used for this species. We address this issue by analysing findings from recently published works on the anatomy, molecular and morphological phylogenetic systematics, and ecology of scophthalmid fishes. The preponderance of evidence supports the strong recommendation to use Scophthalmus as the valid generic name for the tur- bot. Acceptance of this generic name conveys the best information available concerning the systematic relationships of this species, and also serves to simplify the nomenclature of scophthalmid flatfishes in publications on systematics, fisheries and aquaculture, fishery statistics, ichthyofaunal and field guides for the general public, and in various legal and conserva- tion-related documents. This paper reinforces the conclusions of Chanet (2003) with more arguments. RÉSUMÉ. - Scophthalmus Rafinesque, 1810: le nom de genre valide du turbot,S. maximus (Linnaeus, 1758) (Pleuronecti- formes: Scophthalmidae). Depuis 50 ans, le turbot est dénommé dans la littérature soit Scophthalmus maximus (Linnaeus, 1758), soit Psetta maxima (Linnaeus, 1758). Norman (1931) avait montré que le nom valide pour le turbot était Scophthalmus maximus. Cependant, sa recommandation ne fut jamais universellement appliquée, et aujourd’hui la situation reste confuse avec deux noms génériques en usage pour cette espèce. -
Why Are There So Many Flatfishes? Jaw Asymmetry, Diet, and Diversification in the Pleuronectiformes
Why are there so many flatfishes? Jaw asymmetry, diet, and diversification in the Pleuronectiformes Jonathan Chang1 Functional Morphology and Ecology of Fishes Summer 2014 1Department of Ecology and Evolutionary Biology, University of California, Los Angeles, CA 90095, USA. Contact information: Jonathan Chang 610 Charles E. Young Drive S Los Angeles CA 90095 [email protected] Keywords: flatfish, Pleuronectidae, Paralichthyidae, Bothidae, asymmetry, geometric morphometrics, comparative methods, functional morphology Chang 1 Abstract Flatfishes (Actinopterygii: Pleuronectiformes) are a diverse group of teleost fishes, with over 700 species in the order. Jaw asymmetry and diet have been thought to contribute to flatfish diversity but this has not yet been tested in a comparative framework. Here I use geometric morphometric and comparative methods to test whether ocular-blind side asymmetry in flatfish head morphology contributed to flatfish diversification. I find that the repeated convergent evolution of similar morphology, jaw function, and diet likely contribute to the high diversity of flatfishes. Introduction Pleuronectiform fishes are highly diverse, with over 700 described species (Froese and Pauly, 2014). These fishes are characterized by their unique bilateral asymmetry and their benthic ecology. Flatfishes also generally consume one of three main types of prey: buried infauna, pelagic fishes and crustaceans, and a third type intermediate to the first two (de Groot 1971, Tsuruta & Omori 1976). I hypothesize that this specialization into different prey types has driven the diversification and morphological disparity in asymmetry of flatfish species. Methods 12 species of flatfish comprising of 11 genera and 2 families (Table 1) were collected via trawl and seine at these sites: Jackson Beach, [48°31'13.0"N 123°00'35.1"W] and Orcas – Eastsound [48°38'26.9"N 122°52'14.0"W]. -

Brill (Scophthalmus Rhombus) in Subarea 4 and Divisions 3.A and 7.D–E (North Sea, Skagerrak and Kattegat, English Channel)
ICES Advice on fishing opportunities, catch, and effort Celtic Seas and Greater North Sea ecoregions Published 30 June 2020 Brill (Scophthalmus rhombus) in Subarea 4 and divisions 3.a and 7.d–e (North Sea, Skagerrak and Kattegat, English Channel) ICES advice on fishing opportunities Please note: The present advice replaces the advice given in June 2019 for catches in 2021 ICES advises that when the precautionary approach is applied, catches in 2021 should be no more than 2047 tonnes. Management of brill and turbot under a combined species TAC prevents effective control of the single-species exploitation rates and could lead to the overexploitation of either species. ICES advises that management should be implemented at the species level in the entire stock distribution area (Subarea 4 and divisions 3.a and 7.d–e). Note: This advice sheet is abbreviated due to the COVID-19 disruption. The previous biennial advice issued for 2020 and 2021 is attached as Annex 1.The advice for brill is now issued annually.

It is endemic to West Java, Indonesia, specifically around Mount Gede, Mount Pangaro and south of Sukabumi. The Bleeding Toad’s scientific name, cruentata, is from the Latin word meaning “bleeding” because of the frog’s overall reddish-purple appearance and blood-red and yellow marbling on its back. Geographical range The population declined drastically after the eruption of Mount Galunggung in 1987. It is Knowledge believed that other declining factors may be habitat alteration, loss, and fragmentation. Experts Although the lethal chytrid fungus, responsible for devastating declines (and possible Get Involved extinctions) in amphibian populations globally, has not been recorded in this area, the sudden decline in a creekside population is reminiscent of declines in similar amphibian species due to the presence of this pathogen. Only one individual Bleeding Toad was sighted from 1990 to 2003. Part of the range of Bleeding Toad is located in Gunung Gede Pangrango National Park. Future conservation actions should include population surveys and possible captive breeding plans. The production of the IUCN Red List of Threatened Species™ is made possible through the IUCN Red List Partnership. -
1 Students Look at Images of Fish Caught by an Otter Trawl Net Off
BIOGEOGRAPHY OR WHAT HAPPENS TO FISH POPULATIONS DURING EL NIÑO OVERVIEW Students look at images of fish caught by an otter trawl net off southern California. Using fish charts provided in this activity, they identify the fish and record their geographic range. The fish were collected in May 1997, shortly after the beginning of a major El Niño event. Students see what effects the El Niño had on fish population during its early stages. CONCEPTS • In a given area fish populations can change as water conditions (e.g., temperature) change off- shore due to El Niño effects. • Effects of an El Niño occur over time, so the U.S. west coast may not show significant effects for several months after an El Niño begins developing in equatorial waters. MATERIALS • Movie of fish catch included with this activity (activity can be done without the movie) • Fish Keys (included) • “Catch of the Day” sheet (included) • Paper and pencil to record results • Atlas or map with geographical information about the U.S. west coast (if needed) PREPARATION Divide students into small groups. Make copies of Fish Key and Catch of the Day sheets, one for each group. PROCEDURE Engagement An El Niño event is thought to be triggered when steady westward blowing trade winds weaken and even reverse direction. This change in the winds allows the large mass of warm water that is normally located near Australia to move eastward along the equator until it reaches the coast of South America. It then spreads out along the western coasts of the Americas, affecting water temperatures and weather patterns. -
