Consumption Impacts by Marine Mammals, Fish, and Seabirds on The
83 Consumption impacts by marine mammals, fish, and seabirds on the Gulf of Maine–Georges Bank Atlantic herring (Clupea harengus) complex during the years 1977–2002 W. J. Overholtz and J. S. Link Overholtz, W. J. and Link, J. S. 2007. Consumption impacts by marine mammals, fish, and seabirds on the Gulf of Maine–Georges Bank Atlantic herring (Clupea harengus) complex during the years 1977–2002. ICES Journal of Marine Science, 64: 83–96. A comprehensive study of the impact of predation during the years 1977–2002 on the Gulf of Maine–Georges Bank herring complex is presented. An uncertainty approach was used to model input variables such as predator stock size, daily ration, and diet composition. Statistical distributions were constructed on the basis of available data, producing informative and uninformative inputs for estimating herring consumption within an uncertainty framework. Consumption of herring by predators tracked herring abundance closely during the study period, as this important prey species recovered following an almost complete collapse during the late 1960s and 1970s. Annual consumption of Atlantic herring by four groups of predators, demersal fish, marine mammals, large pelagic fish, and seabirds, averaged just 58 000 t in the late 1970s, increased to 123 000 t between 1986 and 1989, 290 000 t between 1990 and 1994, and 310 000 t during the years 1998–2002. Demersal fish consumed the largest proportion of this total, followed by marine mammals, large pelagic fish, and seabirds. Sensitivity analyses suggest that future emphasis should be placed on collecting time-series of diet composition data for marine mammals, large pelagic fish, and seabirds, with additional monitoring focused on the abundance of seabirds and daily rations of all groups. -

In 1999 and 2000, we sampled various fish species to better understand the effect that predation has on Chinook salmon populations. Additionally, we reviewed existing data to get a more complete picture of predation. We collected predators in three areas of the Lake Washington basin where juvenile Chinook salmon may be particularly vulnerable to predatory fishes. Two of these areas, the Cedar River and the south end of Lake Washington are important rearing areas. In these areas, Chinook salmon may be vulnerable because they are small and are present for a relatively long period of time. The other study area, Lake Washington Ship Canal (LWSC; includes Portage Bay, Lake Union, Fremont Cut, and Salmon Bay), is a narrow migratory corridor where Chinook salmon smolts are concentrated during their emigration to Puget Sound. -

Ledeganckstraat 35, B-9000 Gent, Belgium [email protected] 1 21/06/2011 - 10:33:20 Abstract The catfishes (Siluriformes) comprise a particularly diverse teleost clade, from a taxonomic, morphological, biogeographical, ecological and behavioural perspective. The Neotropical Trichomycteridae (the “parasitic” catfishes) are emblematic of this diversity, including fishes with some of the most specialized habits and habitats among teleosts (e.g. hematophagy, lepidophagy, miniaturization, fossorial habitats, altitudinal extremes). Relatively little information is available on general trichomycterid morphology, as most work so far has concentrated on phylogenetically informative characters, with little concern about general descriptive anatomy. In this paper we provide a synthesis of new and previously-available data in order to build a general picture of basal crown group trichomycterid morphology and of its main modifications. We focus on the evolutionary morphology in two relatively distal trichomycterid lineages, i.e. -
Towards a Regional Information Base for Lake Tanganyika Research
RESEARCH FOR THE MANAGEMENT OF THE FISHERIES ON LAKE GCP/RAF/271/FIN-TD/Ol(En) TANGANYIKA GCP/RAF/271/FIN-TD/01 (En) January 1992 TOWARDS A REGIONAL INFORMATION BASE FOR LAKE TANGANYIKA RESEARCH by J. Eric Reynolds FINNISH INTERNATIONAL DEVELOPMENT AGENCY FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS Bujumbura, January 1992 The conclusions and recommendations given in this and other reports in the Research for the Management of the Fisheries on Lake Tanganyika Project series are those considered appropriate at the time of preparation. They may be modified in the light of further knowledge gained at subsequent stages of the Project. The designations employed and the presentation of material in this publication do not imply the expression of any opinion on the part of FAO or FINNIDA concerning the legal status of any country, territory, city or area, or concerning the determination of its frontiers or boundaries. PREFACE The Research for the Management of the Fisheries on Lake Tanganyika project (Tanganyika Research) became fully operational in January 1992. It is executed by the Food and Agriculture organization of the United Nations (FAO) and funded by the Finnish International Development Agency (FINNIDA). This project aims at the determination of the biological basis for fish production on Lake Tanganyika, in order to permit the formulation of a coherent lake-wide fisheries management policy for the four riparian States (Burundi, Tanzania, Zaïre and Zambia). Particular attention will be also given to the reinforcement of the skills and physical facilities of the fisheries research units in all four beneficiary countries as well as to the buildup of effective coordination mechanisms to ensure full collaboration between the Governments concerned. -
