The Vocalisation of the John Dory, Zeus Faber
RESEARCH ARTICLE Barking mad: The vocalisation of the John Dory, Zeus faber 1 1 1,2 Craig A. RadfordID *, Rosalyn L. PutlandID , Allen F.

John Dory (Zeus faber) is a solitary, predatory fish that produces sound when cap- tured, but has not been documented to vocalize under natural conditions (i.e. in the wild). The present study provides the first in-situ recordings of John Dory vocalisations and corre- lates them to behavioural response of snapper (Pagrus auratus) a common species found OPEN ACCESS through New Zealand. Vocalisations or `barks', ranged between 200±600 Hz, with a peak frequency of 312 10 Hz and averaged 139 4 milliseconds in length.

Wales-Ireland Travelogue 2009
WALES AND IRELAND TRIP MAY 12 TO JUNE 4, 2009 What a coincidence! Meaningless, to be sure - but a coincidence, nonetheless. Our trip to the British Isles in 2009 began and ended one day earlier than our trip to Scotland, May 14 to June 5, 2001. (One can only hope that September of this year doesn't hold the same sort of unpleasant surprise that was visited upon us eight years ago.) OK, so I made a "small" error - we are departing two days earlier, not one. And, OK, so it wasn't much of a coincidence, was it? I mean, a real coincidence - one of excruciating consequence - occurred at the Polo Grounds in NYC on October 3, 1951 when Ralph Branca of the Blessed Brooklyn Dodgers was called in to pitch in the 9th inning and, by coincidence, Bobby Thomson of the Bestial New York Giants happened to come to bat, and, by coincidence, Mr. Branca happened to throw a pitch that the aforementioned Mr. Thomson happened to swing at, and, by coincidence, made contact with said pitch and drove it a miserable 309 feet into the first row of the left- field seats of the absurdly apportioned Polo Grounds, thus ending the Dodgers' season and causing a certain 12-year-old, watching on TV, in Brooklyn to burst into tears. Now that was a coincidence! But I digress. Tuesday, May 12 to Wednesday, May 13 Rather than leaving our car at the Seattle Airport Parking Garage (cost for three-plus weeks $468) or at an airport hotel (about $335) we decide to try the new Gig Harbor Taxi (at $95 each way, including tip). -
Demersal and Epibenthic Assemblages of Trawlable Grounds in the Northern Alboran Sea (Western Mediterranean)
SCIENTIA MARINA 71(3) September 2007, 513-524, Barcelona (Spain) ISSN: 0214-8358 Demersal and epibenthic assemblages of trawlable grounds in the northern Alboran Sea (western Mediterranean) ESTHER ABAD 1, IZASKUN PRECIADO 1, ALBERTO SERRANO 1 and JORGE BARO 2 1 Centro Oceanográfico de Santander, Instituto Español de Oceanografía, Promontorio de San Martín, s/n, P.O. Box 240, 39080 Santander, Spain. E-mail: [email protected] 2 Centro Oceanográfico de Málaga, Instituto Español de Oceanografía, Puerto Pesquero s/n, P.O. Box 285, 29640 Fuengirola, Málaga, Spain SUMMARY: The composition and abundance of megabenthic fauna caught by the commercial trawl fleet in the Alboran Sea were studied. A total of 28 hauls were carried out at depths ranging from 50 to 640 m. As a result of a hierarchical clas- sification analysis four assemblages were detected: (1) the outer shelf group (50-150 m), characterised by Octopus vulgaris and Cepola macrophthalma; (2) the upper slope group (151-350 m), characterised by Micromesistius poutassou, with Plesionika heterocarpus and Parapenaeus longirostris as secondary species; (3) the middle slope group (351-640 m), char- acterised by M. poutassou, Nephrops norvegicus and Caelorhincus caelorhincus, and (4) the small seamount Seco de los Olivos (310-360 m), characterised by M. poutassou, Helicolenus dactylopterus and Gadiculus argenteus, together with Chlorophthalmus agassizi, Stichopus regalis and Palinurus mauritanicus. The results also revealed significantly higher abundances in the Seco de los Olivos seamount, probably related to a higher food availability caused by strong localised cur- rents and upwellings that enhanced primary production. Although depth proved to be the main structuring factor, others such as sediment type and food availability also appeared to be important. -

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. -
Fish Species of Saskatchewan
Introduction From the shallow, nutrient -rich potholes of the prairies to the clear, cool rock -lined waters of our province’s north, Saskatchewan can boast over 50,000 fish-bearing bodies of water. Indeed, water accounts for about one-eighth, or 80,000 square kilometers, of this province’s total surface area. As numerous and varied as these waterbodies are, so too are the types of fish that inhabit them. In total, Saskatchewan is home to 67 different fish species from 16 separate taxonomic families. Of these 67, 58 are native to Saskatchewan while the remaining nine represent species that have either been introduced to our waters or have naturally extended their range into the province. Approximately one-third of the fish species found within Saskatchewan can be classed as sportfish. These are the fish commonly sought out by anglers and are the best known. The remaining two-thirds can be grouped as minnow or rough-fish species. The focus of this booklet is primarily on the sportfish of Saskatchewan, but it also includes information about several rough-fish species as well. Descriptions provide information regarding the appearance of particular fish as well as habitat preferences and spawning and feeding behaviours. The individual species range maps are subject to change due to natural range extensions and recessions or because of changes in fisheries management. "...I shall stay him no longer than to wish him a rainy evening to read this following Discourse; and that, if he be an honest Angler, the east wind may never blow when he goes a -fishing." The Compleat Angler Izaak Walton, 1593-1683 This booklet was originally published by the Saskatchewan Watershed Authority with funds generated from the sale of angling licences and made available through the FISH AND WILDLIFE DEVELOPMENT FUND. -
