Despite their distinctive geographic, historic and cultural features, these countries share a common past in that they were all colonized in the frst half of the 20th century, by a motley assemblage of European powers. These were, from North to South: Guinea-Bissau by Portugal; Côte d’Ivoire by France; Togo by Germany, then France; Benin by France; Nigeria by the United Kingdom; Cameroon by Germany, then France and the UK; Gabon (by France); Congo (Brazzaville) by France; Congo (ex-Zaire) by Belgium; and Angola by Portugal. The development trajectory upon which these West African countries found themselves when they became independent was strongly shaped by this colonialism, which was harsh and diffcult to get rid of - particularly for the ex-Portuguese colonies. Traces of colonialism are thus felt at all levels, notably where the struggle for political and economic ‘agency’ after formal independence plunged these countries into perennial political instability (e.g., Guinea Bissau), or long and murderous civil wars and/or wars over natural resources (e.g., Angola, Congo ex-Zaire). Some other countries transited smoothly into neo-colonies, where development and research institutions fail to play their nation-building role, as they serve mainly to maintain previous colonial ties. This has resulted, particularly in the former French colonies, in a general reluctance to transfer knowledge to local institutions. Neo-colonial ties are also illustrated through the profle of exploitation of natural resources, notably fsh stocks, to which the former colonial powers often maintains a privileged access. As a result, West African countries did not develop truly national industrial fsheries, which would have formed an obstacle to the foreign industrial feets that gradually invaded their Exclusive Economic Zones (EEZ). As a consequence, in most of their coastal areas, foreign vessels and the stock depletions they cause(d) hinder the development of the artisanal and local industrial fsheries. This has led to growing tensions, which are only partly alleviated by foreign feets being refagged to the countries in whose waters they operate, and landing the low-value part of their catch locally. The resolution of these tensions, increased by growing demands for fsh by both consumers in Western Europe and East Asia, and the inhabitants of West African countries, will determine whether issues of food security will prevail over the power of international markets. This is the reason why we contrast, for each country, the catches of small- scale fsheries, which mostly enter the local economies, and those of industrial (mostly foreign) fsheries, which tend to hinder their development. The Editors Vancouver, April 2015 Guinea-Bissau - Belhabib and Pauly 1 Fisheries in troubled Waters: a catch reconstruction For Guinea-bissau, 1950-20101 Dyhia Belhabib and Daniel Pauly Sea Around Us, Fisheries Centre, University of British Columbia, 2202 Main Mall, Vancouver, BC, V6T 1Z4, Canada [email protected]; [email protected] abstract Marine fsheries catches of Guinea Bissau were reconstructed to account for sectors that have never been considered previously. Two main sectors were identifed, the large-scale (industrial) sector, which includes foreign industrial catches, the catches of so-called ‘domestic’ vessels, and the discards they both generate. The other main sector consists of the small-scale fsheries, including subsistence, recreational and, most importantly, the artisanal sectors. Catches were estimated at 13 million tonnes between 1950 and 2010, of which 1.6 million tonnes were caught by domestic fsheries. This is much higher than the 207,000 tonnes supplied to the FAO on behalf of Guinea Bissau. A sharp decline in catches is noted over the last decade, probably due to over-exploitation which threatens the food security of the population of Guinea-Bissau. On the other hand, losses due to illegal fsheries are very high, and controlling illegal fshing will go a long way towards improving the status of the fsheries of, and seafood supply to, Guinea Bissau. introduction Guinea Bissau is located at the edge of the Guinea Current Large Marine Ecosystem (LME) and the Canary Current LME between 11°52’N and 15°36’W. Thanks to coastal upwellings and extensive nutrients from river input, the extensive continental shelves off Guinea Bissau – one of the largest in West Africa – within an Exclusive Economic Zone of 106,000 km2 (Figure 1) is home to an estimated one million tonnes of fsheries resources, of which, according to Anon. (2009), 350,000 to 500,000 tonnes could be extracted annually. The history of Guinea Bissau could be described as eventful. Following independence from Portuguese colonial rule in 1974, after a long war of liberation, the frst government was overthrown, and it was only twenty years later that the frst democratic elections were held. A civil war occurred after a few years, in 1998, followed by a frst coup d’état in 1999 and another in 2003. In 2004, the mutiny of a military faction again caused unrest, and eventually led, in 2009, to another coup d’état, after which a new government was elected. The sudden death of the newly elected president in 2012 led to another coup d’état. Unsurprisingly, these events stifed the development, economic and otherwise, of Guinea Bissau, now listed as one of the poorest countries in the world (www. worlbank.org); see also Fernandes (2012). Figure 1. Map of Guinea-Bissau with its Exclusive Economic Zone (EEZ). This, along with agricultural resources limited almost exclusively to cashew nuts, left fsheries as one of the few avenues for economy growth and food security (Dia and Bedingar 2001), although the people of Guinea Bissau were seen as “lazy fshers” in colonial times because they lacked a strong fshing tradition (Bordonaro 2006). Yet, although the country’s offcial statistics show that Guinea Bissau strongly depends on one export commodity – with 99% of the exports, Guinea Bissau is more dependent on cashew nuts than Nigeria is on oil – the fees from foreign fshing access agreements account for 40% of government revenues. This fgure, which is among the highest in the world (Anon. 2013), demonstrates how important fshing is to the country’s economy (Anon. 2010). 1 Cite as: Belhabib, D. and Pauly, D.

As an alternative to shrimp extractive activities, the authors evaluated the rearing of these species in a recirculation culture system. For each species, the grow-out study was carried out in two 120-day production cycles, using 3,300 juveniles of an average length of 25 mm and weight of 0.9 grams in each, distributed in 12 tanks of 1,500 liters and 1.32 m2, at a population density of 208.3 shrimp per m2. The growth parameters were obtained using the von Bertalanffy model based on the length (mm) and age (weeks) data. The adjustments were made in the R environment of the non-linear least-square method. The von Bertalanffy growth model showed a proper fit, with determination coefficients of 0.900 for L. schmitti and 0.841 for F. paulensis. The values of L∞ and k were 172.66 and 0.027 mm for L. schmitti and 110.13 mm and 0.050 for F.

    32nd Annual Report of the PACIFIC MARINE FISHERIES COMMISSION FOR THE YEAR 1979 TO THE CONGRESS OF THE UNITED STATES AND TO THE GOVERNORS AND LEGISLATURES OF WASHINGTON, OREGON, CALIFORNIA, IDAHO, AND ALASKA Pacific Marine Fisheries Commission 528 S.W. Mill Street Portland, Oregon 97201 July 8, 1980 32nd Annual Report of the PACIFIC MARINE FISHERIES COMMISSION FOR THE YEAR 1979 PREFACE The Pacific Marine Fisheries Commission was created in 1947 with the consent of Congress. The Commission serves five member States: Alaska, California, Idaho, Oregon and Washington. The purpose of this Compact, as stated in its Goal and Objectives, is to promote the wise management, utilization, and development of fisheries of mutual concern, and to develop a joint program of protection, enhancement, and prevention of physical waste of such fisheries. The advent of the Fishery Conservation and Management Act {FCMA) of 1976 and amendments thereto has caused spectacular and continuing changes in the management of marine fisheries in the United States. The FCMA created the Fishery Conservation Zone (FCZ) between 3 and 200 nautical miles offshore, established 8 Regional Fishery Management Councils with authority to develop fishery management plans within the FCZ, and granted the Secretary of Commerce the power to regulate both domestic and foreign fishing fleets within the FCZ. The FCMA greatly modified fishery management roles at state, interstate, national and international levels. The Pacific Marine Fisheries Commission recognized early that its operational role would change as a result of possible functional overlaps with the two regional fishery management councils established on the Pacific Coast. On the one hand, the FCMA provides non-voting Council membership to the Executive Directors of the interstate Marine Fisheries Commissions, thus assuring active participation as the Councils deliberate on fishery matters of concern to the States.

Doremus_Final_Web_Ready_FINAL_12May2013 7/18/2013 4:24 PM WHY INTERNATIONAL CATCH SHARES WON’T SAVE OCEAN BIODIVERSITY Holly Doremus* Skepticism about the efficacy and efficiency of regulatory approaches has produced a wave of enthusiasm for market-based strategies for dealing with environmental conflicts. In the fisheries context, the most prominent of these strategies is the use of “catch shares,” which assign specific proportions of the total allowable catch to individuals who are then free to trade them with others. Catch shares are now in wide use domestically within many nations, and there are increasing calls for implementation of internationally tradable catch shares. Based on a review of theory, empirical evidence, and two contexts in which catch shares have been proposed, this Article explains why international catch shares are not likely to arrest the decline of ocean biodiversity.

    - 1 - This paper can be freely cited without prior reference to the authors International Council ICES CM 2007/D:21 for the Exploration Theme Session D: Comparative Marine Ecosystem of the Sea (ICES) Structure and Function: Descriptors and Characteristics Fronts in the World Ocean’s Large Marine Ecosystems Igor M. Belkin and Peter C. Cornillon Abstract. Oceanic fronts shape marine ecosystems; therefore front mapping and characterization is one of the most important aspects of physical oceanography. Here we report on the first effort to map and describe all major fronts in the World Ocean’s Large Marine Ecosystems (LMEs). Apart from a geographical review, these fronts are classified according to their origin and physical mechanisms that maintain them. This first-ever zero-order pattern of the LME fronts is based on a unique global frontal data base assembled at the University of Rhode Island. Thermal fronts were automatically derived from 12 years (1985-1996) of twice-daily satellite 9-km resolution global AVHRR SST fields with the Cayula-Cornillon front detection algorithm. These frontal maps serve as guidance in using hydrographic data to explore subsurface thermohaline fronts, whose surface thermal signatures have been mapped from space. Our most recent study of chlorophyll fronts in the Northwest Atlantic from high-resolution 1-km data (Belkin and O’Reilly, 2007) revealed a close spatial association between chlorophyll fronts and SST fronts, suggesting causative links between these two types of fronts.

  • Seafood Traceability for Fisheries Compliance – Country- Level Support for Catch Documentation Schemes
    ISSN 2070-7010 FAO 619 FISHERIES AND AQUACULTURE TECHNICAL PAPER 619 Seafood traceability for fisheries compliance Country-level support for catch documentation schemes Seafood traceability for fisheries compliance This document explores ways in which individual countries in seafood supply chains can, in their capacities as coastal, flag, port, processing or end-market states, contribute to maximizing the effectiveness of catch documentation schemes. The focus is on the traceability of seafood consignments, but the authors also explore other important compliance mechanisms that are not directly related to traceability but – that support the effective implementation of catch documentation schemes at the Country-level support for catch documentation schemes country level. The document explains which traceability mechanisms are built into catch documentation schemes, and which additional support mechanisms must be provided by individual countries along seafood supply chains. The study finds that traditional fisheries monitoring, inspection and sanctioning mechanisms are of primary importance with regard to flag, coastal and end-market states, whereas effective country-level traceability mechanisms are critical of particular importance in port and processing states.

Twenty-four cross bred weaner (8 weeks old) rabbits comprising twelve each of bucks and does were randomly allocated according to sex and feed supplement (conventional anticoccidia drug and garlic) in a 2x2 factorial arrangement. Data were collected on growth performance, faecal microbial population and carcass yield and analysed using ANOVA. Result showed that neither sex nor feed supplement had significant (P>0.05) effect on the growth performance of weaner rabbits. Coccidial load was progressively and completely eliminated in bucks and does from the baseline population of 1680epg and 600epg, respectively with rabbits fed diet supplemented with garlic. Also, does fed diet supplemented with commercial coccidiostat had complete coccidial load elimination from 5200epg at 8th week to the 16th week. Helminthic load (3800epg) recorded with bucks fed diet supplemented with garlic at the beginning of study were totally eliminated at the end of the study (56d).
