European Anchovy Engraulis Encrasicolus (Linnaeus, 1758) From
European anchovy Engraulis encrasicolus (Linnaeus, 1758) from the Gulf of Annaba, east Algeria: age, growth, spawning period, condition factor and mortality Nadira Benchikh, Assia Diaf, Souad Ladaimia, Fatma Z. Bouhali, Amina Dahel, Abdallah B. Djebar Laboratory of Ecobiology of Marine and Littoral Environments, Department of Marine Science, Faculty of Science, University of Badji Mokhtar, Annaba, Algeria. Corresponding author: N. Benchikh, [email protected] Abstract. Age, growth, spawning period, condition factor and mortality were determined in the European anchovy Engraulis encrasicolus populated the Gulf of Annaba, east Algeria. The age structure of the total population is composed of 59.1% females, 33.5% males and 7.4% undetermined. The size frequency distribution method shows the existence of 4 cohorts with lengths ranging from 8.87 to 16.56 cm with a predominance of age group 3 which represents 69.73% followed by groups 4, 2 and 1 with respectively 19.73, 9.66 and 0.88%. The VONBIT software package allowed us to estimate the growth parameters: asymptotic length L∞ = 17.89 cm, growth rate K = 0.6 year-1 and t0 = -0.008. The theoretical maximum age or tmax is 4.92 years. The height-weight relationship shows that growth for the total population is a major allometry. Spawning takes place in May, with a gonado-somatic index (GSI) of 4.28% and an annual mean condition factor (K) of 0.72. The total mortality (Z), natural mortality (M) and fishing mortality (F) are 2.31, 0.56 and 1.75 year-1 respectively, with exploitation rate E = F/Z is 0.76 is higher than the optimal exploitation level of 0.5. -

Joey Morrison Ethnographic Fieldschool
Joey Morrison Ethnographic Fieldschool - Peru Dr. Michelle Grocke 7/13/18 Local Knowledge and Global Trends: Fishing, Climate, and Industrialization on the Peruvian Coast Ethnographic research and the discipline-specific methods such as pile sorting and free listing are not only the cornerstone of the field of anthropology, but they complement the research of numerous disciplines ranging from geography to economics and served as the cornerstone for the field of anthropology. Although there has been collaboration in the past, currently, the incorporation of and the collaboration with “ethno” disciplines are on the rise. These schools of thought effectively combine ethnographic methods and anthropological analytical lenses to their long-established discipline-specific methods, resulting in “ethnohistory” or “ethnoecology.” The benefits of these mergers are powerful. Ethnographic methods and the resulting analyses offers intimate, lived- experience, grassroots glimpses into intricate, complex, and previously impenetrable cultural domains. Consequently, these interdisciplinary approaches not only bear the potential to revolutionize the ways in which research disciplines ask questions and approach problems, but they can enhance the robusticity of a research project, complement existing literature, and even dispel assumptions. My research question, in many ways, emerged from assumptions and the potential for ethnography to dispel problematic generalizations will emerge throughout this ethnography. I aim to demonstrate the ways in which ethnographic accounts can enhance and provide a more detailed image into the complexities of climate change and global development at local levels. Due to the myriad ways in which the lives of coastal fisherman are intimately enmeshed with the natural world, in this case, the coast, the lived-experience of these fishermen can yield powerful insights into how global climatic and macroeconomic trends are actually being experienced on a local scale. -

The Peruvian Anchoveta Case
Coupled Ecosystem/Supply Chain Modelling of Fish Products from Sea to Shelf: The Peruvian Anchoveta Case Angel Avadı´1,2*, Pierre Fre´on2, Jorge Tam3 1 Universite´ Montpellier 2– Sciences et Techniques, Montpellier, France, 2 Institut de Recherche pour le De´veloppement (IRD), UMR212 EME IFREMER/IRD/UM2, Se`te, France, 3 Instituto del Mar del Peru´ (IMARPE), Callao, Peru Abstract Sustainability assessment of food supply chains is relevant for global sustainable development. A framework is proposed for analysing fishfood (fish products for direct human consumption) supply chains with local or international scopes. It combines a material flow model (including an ecosystem dimension) of the supply chains, calculation of sustainability indicators (environmental, socio-economic, nutritional), and finally multi-criteria comparison of alternative supply chains (e.g. fates of landed fish) and future exploitation scenarios. The Peruvian anchoveta fishery is the starting point for various local and global supply chains, especially via reduction of anchoveta into fishmeal and oil, used worldwide as a key input in livestock and fish feeds. The Peruvian anchoveta supply chains are described, and the proposed methodology is used to model them. Three scenarios were explored: status quo of fish exploitation (Scenario 1), increase in anchoveta landings for food (Scenario 2), and radical decrease in total anchoveta landings to allow other fish stocks to prosper (Scenario 3). It was found that Scenario 2 provided the best balance of sustainability improvements among the three scenarios, but further refinement of the assessment is recommended. In the long term, the best opportunities for improving the environmental and socio-economic performance of Peruvian fisheries are related to sustainability-improving management and policy changes affecting the reduction industry. -

Caixa Postal 42494, 04218-970. São Paulo, SP, Brazil. E-mail: [email protected] Engraulis nattereri Steindachner, 1880 was described on the basis of five specimens collected in Pará during the Nathaniel Thayer Expedition. Later on, the species was assigned to Anchoviella by Fowler (1941). Including Anchoviella nattereri (Steindachner, 1880), Anchoviella comprises 17 small to medium-sized valid species (20–160 mm standard length), nine of them distributed in freshwaters of the Amazon, Essequibo, Corantijn and Orinoco river basins, and other eight brackish and marine species distributed along the Atlantic and Pacific coasts of North, Central and South America (Loeb & Figueiredo, 2014). Although the generic-level classification of E. nattereri within Anchoviella does not show any controversy, the characteristics provided by Steindachner (1880) in the original description of Engraulis nattereri do not allow its proper synonymization with any valid species of the Engraulidae. Thus, herein we discuss the taxonomic status of Engraulis nattereri, poiting out the reasons -
