This book was released on 2006 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: This workshop stressed that the concept of reference points (RPs) needs to be closely connected to the management objective of concerned fisheries, taking into account various parameters such as maximum sustainable yield, economic and social benchmark and environment concern. Participants stressed the need to define different RPs for each dimension of management or to identify a single RP aimed at ensuring the sustainability of the system, thereby no longer limited to biological aspects. A review of possible approaches to setting RPs and indicators for Black Sea fisheries emphasized the dynamic nature of recent ecosystem changes. The traffic light approach was illustrated as a means of following dynamic changes and gaining a broad perspective on events at the ecosystem level. The workshop outlined the main RPs obtained by applying the bio-economic optimization models of effort and effort-catch as derived from the theory of population dynamics.

Book Synopsis Present Market Situation and Prospects of Meagre (Argyrosomus Regius), as an Emerging Species in Mediterranean Aquaculture by : Marie-Christine Monfort
Download or read book Present Market Situation and Prospects of Meagre (Argyrosomus Regius), as an Emerging Species in Mediterranean Aquaculture written by Marie-Christine Monfort and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2010 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document draws the picture of the existing market of meagre and describes the possible routes for development. Meagre culture started in France and in Italy in the late '90s and is developing in the Mediterranean Region, jumping from a few tonnes in 2 000 to over 10 000 tonnes expected in 2010, highlighting the appearance of a new aquaculture species on the market. Indeed, based on its aquaculture characteristics, meagre has the potential to become a mass market species, moving from the present position of a niche species with a limited production directed to selected market segments. The paper recommends some actions to be undertaken to consolidate good conditions for future growth and to reduce commercial risks.

Book Synopsis Fish Trade Among Mediterranean Countries by : Loretta Malvarosa
Download or read book Fish Trade Among Mediterranean Countries written by Loretta Malvarosa and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2010 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this paper is to analyse the trade in fish and fishery products in the Mediterranean basin. With reference to the fisheries sector, it appears that the influence of market forces on the management of fisheries (and vice-versa) is increasing. After an overview of recent trends in fishery production, the study focuses on the exchange of fishery products, based on data from UN-Comtrade and FAO and Eurostat data. The core of the study comprises an analysis of the fish trade between the two sides of the Mediterranean basin, the EU and the non-EU countries. At the European level, the trade in fish products between the northern and the southern Mediterranean is of particular importance when considering recent in production and consumption, as well as the legal framework covering both the production and trade sides of the fishery sector. The cross-sectoral analysis of fishery production and trade provides a number of conclusions and lessons for the future of fishery management.

Book Synopsis Organic Aquaculture by : Giuseppe Lembo
Download or read book Organic Aquaculture written by Giuseppe Lembo and published by Springer. This book was released on 2019-03-28 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses, reviews and evaluates key themes in organic aquaculture and is set out to show how these relate to the challenges and bottlenecks for a responsible organic aquaculture production in Europe. The key themes reflect the main challenges facing the organic aquaculture industry: guarantee and certification system, nutrition, reproduction, production system design and animal welfare. In addition, it assesses the impact of new and future potential development of new knowledge to update and modify the criteria and standards for organic aquaculture. Organic aquaculture is an alternative production approach driven by the growing interest in sustainable utilization of resources. It is rightly viewed as an important contributor to the economy and to the well-being and health of communities. This work will contribute to the scientific knowledge that needs to strengthen effective organic aquaculture. The collation of information on research and data will be of applied value to researchers, university students, end users and policy authorities in the EU and worldwide.
Book Synopsis Marketing of Aquacultured Seabass and Seabream from the Mediterranean Basin by : Marie-Christine Monfort
Download or read book Marketing of Aquacultured Seabass and Seabream from the Mediterranean Basin written by Marie-Christine Monfort and published by Food & Agriculture Org.. This book was released on 2007 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mediterranean finfish species such as the European seabass and the gilthead seabream have, over the last two decades, been attracting considerable attention among aquaculturists and investors. The net result has been a rapid increase in the supply of the finfish to European markets. Accessing these markets with the right product at the right price is a key factor in the success of any commercial aquaculture project. This report describes the current status of the European market for these and other finfish species and the major characteristics of marketing farmed fish in the Mediterranean basin. Part 1 of the report gives an overview of the global European market, including developments in finfish production and marketing performance. Part 2 reviews major market traits of the European seabass and the gilthead seabream as well as other finfish including tilapia. It discusses suppliers to Europe, prices, marketing strategies and product types. Part 3 presents important European market characteristics such as product quality, consistency of supplies and competitive prices. Part 4 gives key figures regarding aquaculture production by country. Part 5 outlines farming technologies that may be more suited to certain Mediterranean countries and may offer new investment opportunities.--Publisher's description.

Download or read book An Adaptive Approach for the Improvement of Fishery Statistical Systems in Mediterranean Countries written by Salvatore R. Coppola and published by Food & Agriculture Org.. This book was released on 2007 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The establishment of fishery statistics and information systems in many countries of the General Fishery Commission for the Mediterranean (GFCM) continues to be considered a high priority activity, and the need to monitor fishing activities and provide fishery management at all levels with accurate, reliable and timely data which can interact with stock assessment and economic and socioeconomic studies for decision-making is constantly increasing. In accordance with FAO and the GFCM mandate, the objective of MedStat is to contribute to the sustainable and responsible fisheries management of fishery resources and fish production in the Mediterranean Sea through the implementation of a long-lasting statistical and information programme which will provide a sound basis for decision-making. The whole national statistical system developed within this activity consists of a set of databases and associated statistical data collection and implementation methodologies and procedures that primarily cover the fishing vessel census, catch and effort surveys, and other surveys targeting monitoring and management issues. Strengthening the capability of the fisheries institutions of the Mediterranean countries in marine fishery statistics and information systems, with a view to meeting the relevant national needs and requirements for participation in, and complementing in its entirety, the Mediterranean Fishery Statistics and Information System, is also considered a priority issue of MedStat.

This book was released on 2007 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thirty-first session of the General Fisheries Commission for the Mediterranean (GFCM) reviewed the intersessional activities of its Scientific Advisory Committee (SAC) and its Committee on Aquaculture (CAQ) and held the first session of its Compliance Committee. Based on advice from SAC and proposals by Members, the GFCM adopted: three Resolutions, including two related to the GFCM statistical framework and one on the use of the 40 mm square mesh size in the codend of trawlnets. The Commission also adopted binding recommendations on fisheries management, including diamond mesh size of trawlnets and the Pelagos Sanctuary for the conservation of marine mammals, as well as three Recommendations emanating from the International Commission for the Conservation of Atlantic Tunas (ICCAT) on bluefin tuna and on transshipment at sea. The GFCM strengthened the mandate of CAQ and adopted a new set up and modus operandi for the subsidiary bodies of the Committee. The Commission decided to strengthen its activities in the Black Sea. It acknowledged the importance of the five regional projects supporting the activities of the Committees and endorsed a series of amendments to its Rules of Procedure. The Commission agreed on its programme of work and adopted its budget for 2007, including the establishment within the Secretariat of a post of Aquaculture specialist.

Meeting and published by Food & Agriculture Org.. This book was released on 2006 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fifth meeting of the FAO Working Group on the Assessment of Small Pelagic Fish off Northwest Africa was held in Nouadhibou, Mauritania, from 26 April to 5 May 2005. The meeting continued to focus on data quality and on the analysis of trends in the basic data (landings, catch, effort, abundance, length and age distribution) and trends in the fishery independent survey data. The structure of the report is the same as that of the previous Working Group report (FAO, 2004), with the addition of two chapters, one on bonga (Ethmalosa fimbriata) and one on anchovy (Engraulis encrasicolus). A separate section is devoted to each of the main groups of species (sardine, sardinella, horse mackerel, chub mackerel, bonga and anchovy). For each of these, standardised information is given on stock identity, fisheries, abundance indices, sampling, biological data, assessment, management recommendations and future research. In the absence of reliable length and/or age compositions, the Working Group used production models for all stocks. The results of the assessments indicate that the sardine stock in Zone C is not fully exploited and the Working Group hence noted that the total catch level may be temporarily increased but should be adjusted to natural changes in the stock. A constant monitoring of the stock abundance and structure, by scientific surveys, independent from catch data, should be ensured, to detect unanticipated changes that may require urgent management measures. As regards the central stock of sardine (Zones A+ B), it is recommended not to increase catches above the average level of the last five years (600 000 tonnes). The stock of round sardinella was found to be fully exploited and it was hence recommended not to increase catches of sardinella above the current level of 400 000 tonnes (2004). As a precautionary approach, the Working Group recommended not to increase catches above the average level of the last five years for the horse mackerels (80 000 tonnes for Trachurus trachurus and 170 000 tonnes for T. trecae) and not to increase catches above the 2004 level for chub mackerel (220 000 tonnes). For bonga the Working Group recommended as a precautionary measure that the catch level should not exceed the average over the last five years (42 000 tonnes) and for anchovy the catch level should not exceed the average over the last three years (160 000 tonnes). In formulating the results of the assessments, the Working Group noted that it lacked a set of uniform reference points and management objectives for all stocks in the area. The Group noted that the selection of appropriate reference points required more time than was available during the meeting. It was therefore decided that some members will look further into this problem, working by correspondence, and present a working paper at the 2006 meeting. At that meeting the Working Group will attempt to agree on a common policy concerning the way it presents its management advice for the various stocks.
