  • Abstract for Submission to the 11Th International Coral Reef
    Reef Fish Spawning Aggregations in Aceh, Sumatra: Local Knowledge of Occurrence and Status Authors: Campbell S.J., Mukmunin, A., Prasetia, R The Wildlife Conservation Society, Indonesian Marine Program, Jalan Pangrango 8, Bogor 16141, Indonesia Reef Fish Spawning Aggregations (FSA) are critical in the life cycle of the fishes that use this reproductive strategy as sources of larvae, but are also highly vulnerable to over exploitation. With the exception of the Komodo (Pet et al. 2005) little if any research has been focused on FSAs in Indonesia. Interview surveys were conducted among fishing communities on the island of Weh in northern Aceh in order to determine the level of awareness of FSAs among fishers; which reef fish species form FSAs; sites of aggregation formation; seasonal patterns; and to assess fishing pressure on and status of FSAs. Results show that many fishers possess reliable knowledge of spawning areas, species and times. Possible FSAs were reported from a number of areas on Weh island inside and outside protected areas. Of the 47 species of fish mentioned by respondents, we conclude that six species are very likely to form spawning aggregations in marine waters of Weh island. All six species were mentioned by more than 10 fishers, and included Bolbometopoton muricatum (Scaridae: Bumpheaded parrotfish), Cepahpholis miniata (Serranidae: Coral grouper) Variola louti (Serranidae: Yellow Edged Lyretail), Cheilinus undulatas (Labridae: Napolean wrasse), Thunnus albacares (Yellow fin tuna) and Caranx lugubris (Carangidae: Black Jack Trevally). FSAs in Aceh were areas targeted by fishers, although many were inside existing marine protected areas where prohibitions on netting from boats are in place.

  • Early Stages of Fishes in the Western North Atlantic Ocean Volume
    ISBN 0-9689167-4-x Early Stages of Fishes in the Western North Atlantic Ocean (Davis Strait, Southern Greenland and Flemish Cap to Cape Hatteras) Volume One Acipenseriformes through Syngnathiformes Michael P. Fahay ii Early Stages of Fishes in the Western North Atlantic Ocean iii Dedication This monograph is dedicated to those highly skilled larval fish illustrators whose talents and efforts have greatly facilitated the study of fish ontogeny. The works of many of those fine illustrators grace these pages. iv Early Stages of Fishes in the Western North Atlantic Ocean v Preface The contents of this monograph are a revision and update of an earlier atlas describing the eggs and larvae of western Atlantic marine fishes occurring between the Scotian Shelf and Cape Hatteras, North Carolina (Fahay, 1983). The three-fold increase in the total num- ber of species covered in the current compilation is the result of both a larger study area and a recent increase in published ontogenetic studies of fishes by many authors and students of the morphology of early stages of marine fishes. It is a tribute to the efforts of those authors that the ontogeny of greater than 70% of species known from the western North Atlantic Ocean is now well described. Michael Fahay 241 Sabino Road West Bath, Maine 04530 U.S.A. vi Acknowledgements I greatly appreciate the help provided by a number of very knowledgeable friends and colleagues dur- ing the preparation of this monograph. Jon Hare undertook a painstakingly critical review of the entire monograph, corrected omissions, inconsistencies, and errors of fact, and made suggestions which markedly improved its organization and presentation.

  • Caranx Lugubris (Black Jack)
    UWI The Online Guide to the Animals of Trinidad and Tobago Ecology Caranx lugubris (Black Jack) Family: Carangidae (Jacks and Pompanos) Order: Perciformes (Perch and Allied Fish) Class: Actinopterygii (Ray-finned Fish) Fig. 1. Black jack, Caranx lugubris. [http://marinebio.org/upload/Caranx-lugubris/1.jpg, downloaded 14 February 2016] TRAITS. Being built for speed, Caranx lugubris have a steep sloping head with a body that tapers down to a very narrow tail (Lin and Shao, 1999). The colour of the body and head are almost uniformly greyish-brown to black, they have a deeply forked tail (Fig. 1), and the average body length is around 70cm (Humann, 1989). The teeth of the upper jaw include strong canines, and there are about 8 upper and 18-21 lower gill-rakers on the gill arches. DISTRIBUTION. Caranx lugubris is widely distributed in tropical waters worldwide (Fig. 2), with a circumtropical distribution (Smith-Vaniz, 1986). This includes the waters of the Indian Ocean, Pacific, the Atlantic including the Gulf of Mexico and the Caribbean (Smith-Vaniz et al., 2015). UWI The Online Guide to the Animals of Trinidad and Tobago Ecology HABITAT AND ACTIVITY. This species of fish lives in offshore waters at depths of 10-350m (Lieske and Myers, 1994). This species is a bentho-pelagic marine fish that dwells in coral reefs, at the edges of reefs and rocks (Carpenter, 2002). They tend to form schools and primarily feed on other fish (Smith-Vaniz et al., 2015). They tend to live in solitude or in schools consisting of up to 30 individuals (Fig.

Del mismo modo, es difícil entender los agradecimientos de una tesis hasta que pones el punto y final. Es en este momento cuando se puede percibir la gratitud que sientes a todas las personas que han estado presentes durante esa etapa, ya bien sea codo a codo o simplemente trayéndote un café calentito en el momento preciso. Pero también es cierto que, entre toda esa gente que ha estado ahí, hay pocas caras que se dibujan clara e intensamente en mi cabeza. En primerísimo lugar, me gustaría dar las gracias de una manera muy especial a Montse por muchos, muchísimos motivos: por darme cariño y amistad desde el día en que nos conocimos; porque a lo largo de esta década hemos compartido muchísimos momentos alegres, acompañados de risas y carcajadas, pero también los más tristes de mi vida, inundados de lágrimas y angustia; por estar ahí para lo que sea, para todo, y tener siempre tendida su mano amiga; por escucharme una y otra vez, sin cansarse, y aconsejarme sabiamente; por confiar en mí y guiarme, no solo durante el desarrollo de esta tesis, sino también en mi formación y día a día; por su eterna paciencia;… y, sobre todo, por poner en mi vida al “morenocho”, ese pequeño loquito tímido que me comería a besos.

  • Predator-Prey Relations at a Spawning Aggregation Site of Coral Reef Fishes
    MARINE ECOLOGY PROGRESS SERIES Vol. 203: 275–288, 2000 Published September 18 Mar Ecol Prog Ser Predator-prey relations at a spawning aggregation site of coral reef fishes Gorka Sancho1,*, Christopher W. Petersen2, Phillip S. Lobel3 1Department of Biology, Woods Hole Oceanographic Institution, Woods Hole, Massachusetts 02543, USA 2College of the Atlantic, 105 Eden St., Bar Harbor, Maine 04609, USA 3Boston University Marine Program, Woods Hole, Massachusetts 02543, USA ABSTRACT: Predation is a selective force hypothesized to influence the spawning behavior of coral reef fishes. This study describes and quantifies the predatory activities of 2 piscivorous (Caranx melampygus and Aphareus furca) and 2 planktivorous (Melichthys niger and M. vidua) fishes at a coral reef fish-spawning aggregation site in Johnston Atoll (Central Pacific). To characterize preda- tor-prey relations, the spawning behavior of prey species was quantified simultaneously with mea- surements of predatory activity, current speed and substrate topography. The activity patterns of pis- civores was typical of neritic, daylight-active fish. Measured both as abundance and attack rates, predatory activity was highest during the daytime, decreased during the late afternoon, and reached a minimum at dusk. The highest diversity of spawning prey species occurred at dusk, when pisci- vores were least abundant and overall abundance of prey fishes was lowest. The abundance and predatory activity of the jack C. melampygus were positively correlated with the abundance of spawning prey, and therefore this predator was considered to have a flexible prey-dependent activ- ity pattern. By contrast, the abundance and activity of the snapper A. furca were generally not corre- lated with changes in abundance of spawning fishes.

    TheULTIMATE ATOLL A Saltwater Utopia for the Adventuresome Angler by Dylan Rose he moment I set foot on Christmas Island my life was changed forever. My first visit was a metaphorical abstraction of the island’s vibe, culture, warmth and relaxed pace. As I stepped off of the big Fiji Airways 737 onto the tarmac I noticed from Tbehind the airport fence a small gathering of villagers quietly watching us deplane. Some of the island’s sun-kissed, bronzed-faced children were standing behind the chain link fence, smiling and waving excitedly. I Dylan Rose tracks a GT that turned to look behind me expecting to see a familiar party waving back, was spotted from the boat. but I soon realized their brilliant white smiles were actually for me and my Photo: Brian Gies intrepid gang of arriving fly anglers. PAGE 1 The ULTIMATE ATOLL Of all the places I’ve traveled, the feeling of being truly welcome in a the Pacific Ocean. Captain Cook landed on the island on Christmas Eve in foreign land is the strongest at Christmas Island. It’s the attribute about the 1777 and I can only imagine what a great holiday it might have been if he had place that connects me most to it.

From the giddy bouncing children swimming in the boat harbor again by the United States in the 1960s, Christmas Island and its magnificent to the villagers tending their chores; to the guides and their families, the lodge population of seabirds got a front row view of the inception of the atomic age.
