Field Identification Guide to the Sharks and Rays of the Red Sea and Gulf of Aden
FAO SPECIES IDENTIFICATION GUIDE FOR FISHERY PURPOSES ISSN 1020-6868 FIELD IDENTIFICATION GUIDE TO THE SHARKS AND RAYS OF THE RED SEA AND GULF OF ADEN PERSGA FAO SPECIES IDENTIFICATION GUIDE FOR FISHERY PURPOSES FIELD IDENTIFICATION GUIDE TO THE SHARKS AND RAYS OF THE RED SEA AND GULF OF ADEN by Ramón Bonfil Marine Program Wildlife Conservation Society Bronx, New York, USA and Mohamed Abdallah Strategic Action Program Regional Organization for the Conservation of the Environment of the Red Sea and Gulf of Aden Jeddah, Saudi Arabia FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS Rome, 2004 iii PREPARATION OF THIS DOCUMENT This document was prepared under the coordination of the Species Identification and Data Programme of the Marine Resources Service, Fishery Resources and Environment Division, Fisheries Department, Food and Agriculture Organization of the United Nations (FAO). This field guide is largely based on material prepared for training courses on elasmobranch identification delivered in the region by the first author, and promoted by the Regional Organization for the Conservation of the Environment of the Red Sea and Gulf of Aden (PERSGA), as an activity of PERSGA’s Strategic Action Programme (SAP) towards capacity building and technical assistance in the Red Sea and Gulf of Aden region. Printing was supported by Japanese Government funds. The increasing recognition of the significance of sharks and batoid fishes as ecosystem health indicators, as well as their particular importance in exploited ecosystems in the Red Sea and the Gulf of Aden, have been key considerations to promote the preparation of this Field Guide. Furthermore, in recent years the reported catches of elasmobranchs in the Red Sea and the Gulf of Aden showed a marked increase. -

Simple Summary: Paradise fish (Macropodus opercularis) has been a favored subject of behavioral research during the last decades of the 20th century. Lately, however, with a massively expanding genetic toolkit and a well annotated, fully sequenced genome, zebrafish (Danio rerio) became a central model of recent behavioral research. But, as the zebrafish behavioral repertoire is less complex than that of the paradise fish, the focus on zebrafish is a compromise. With the advent of novel methodologies, we think it is time to bring back paradise fish and develop it into a modern model of Citation: Rácz, A.; Adorján, G.; behavioral and evolutionary developmental biology (evo-devo) studies. The first step is to define the Fodor, E.; Sellyei, B.; Tolba, M.; housing and husbandry conditions that can make a paradise fish a relevant and trustworthy model. -

Analysis of the Diet Between an Invasive and Native Fishes in the Peruvian Amazon. Anthony Mazeroll [email protected] Introduct
Analysis of the diet between an invasive and native fishes in the Peruvian Amazon. Anthony Mazeroll [email protected] Introduction Non-native species are the second greatest threat to global species biodiversity after land development (Vitousek, D'Antonio, Loope, Rejmanek, & Westbrooks, 1997). Due to the magnitude of this threat, it is vital that the impacts of exotic species are understood. Fish biodiversity is especially threatened by the ecological changes caused by non-native species (Gozlan, Britton, Cowx, & Copp, 2010). Having higher species diversity allows more ecological processes to take place, protecting the resources of that system, and making it more resilient to change (Folke, 2006). Adding outside inputs, such as additional non-native species, into an ecosystem can have beneficial or compromising effects depending on the amount and type. Invasive species have been shown to reduce native species richness and diversity of native organisms. Some have argued that the transportation of species from one ecosystem to another is actually beneficial for diversity, and non-native species are not really an environmental “problem”. Introductions of non-native species increase diversity at a local level because in the short term there will be a lag time where both non-native and natives can coexist (Lodge, Stein, Brown, Covich, Bronmark, Garvey and Klosiewski, 1998). Species entering a new ecosystem have to pass through a gauntlet of barriers before they can become established. The usual progression of invasion is: transportation to the new ecosystem, initial establishment, spread to a larger region, and then naturalization into the new community (Marchetti, Light, Moyle, and Viers, 2004). -

This is most common measure to reproductive potential. Dimorphism – differences in size or body shape between males and females Dichromatism – differences in color between males and females Bioenergetics – the balance of energy between growth, reproduction and metabolism REPRODUCTIVE ANATOMY Different between sexes Different depending on the age/ size of the fish May only be able to determine by internal examination Reproductive tissues are commonly paired structures closely assoc with kidneys FEMALE OVARIES (30 TO 70%) MALE TESTES (12% OR <) Anatomy hagfish, lamprey: single gonads no ducts; release gametes into body cavity sharks: paired gonads internal fertilization sperm emitted through cloaca, along grooves in claspers chimaeras, bony fishes: paired gonads external and internal fertilization sperm released through separate opening most teleosts: ova maintained in continuous sac from ovary to oviduct exceptions: Salmonidae, Anguillidae, Galaxidae, -

Ultimate Kenya
A pair of fantastic Sokoke Scops Owls. (DLV). All photos taken by DLV during the tour. ULTIMATE KENYA 1 – 20 / 25 APRIL 2017 LEADER: DANI LOPEZ-VELASCO Kenya lived up to its reputation of being one of the most diverse birding destinations on our planet. Once again, our Ultimate Kenya recorded a mind-boggling total of more than 750 species. This was despite the fact that we were prioritizing Kenyan specialities (a task in which we were extremely successful) rather than going all out for a huge list! 1 BirdQuest Tour Report: Ultimate Kenya www.birdquest-tours.com The first leg of our epic adventure saw us focusing on the Arabuko-Sokoke Forest where the birding is tough but the rewards are great. Over the course of the two and a half days our talented local guide helped us find all of the main specialities, with the exception of the difficult Clarke’s Weavers, which were presumably on their recently discovered breeding grounds in marshes to the north. Crested Guineafowl and Northern Carmine Bee-eater. We spent much time creeping along sandy tracks, gradually finding our targets one by one. We succeeded in getting great views of a number of skulkers, including a rather showy East Coast Akalat on our last afternoon, some reclusive Eastern Bearded Scrub Robins, a very obliging Red-tailed Ant Thrush and skulking Fischer’s and Tiny Greenbuls. Once in the Brachystegia we kept our eyes and ears open for roving flocks of flock-leader Retz’s and Chestnut-fronted Helmet Shrikes, and with these we found awkward Mombasa Woodpeckers and a single Green-backed Woodpecker, and a variety of smaller species including Black-headed Apalis, Green Barbet, Eastern Green Tinkerbird, dainty Little Yellow Flycatchers, Forest Batis, Pale Batis, cracking little Amani and Plain-backed Sunbirds and Dark-backed Weaver. -

While the labyrinth gills of labyrinth fishes are relatively small and primarily organ may be one of the most obvious traits, others, such as excrete the waste products ammonia and carbon dioxide. bubble nest building for reproduction, are also associated In fact, many labyrinth fishes are obligate air breathers, with this adaptation. The bubble nest allows eggs to develop meaning they must breathe at the surface to survive. in environments with elevated temperature and low pH and Other fishes have evolved a number of solutions to allow dissolved oxygen, relatively free of predators.
