  • Models for an Ecosystem Approach to Fisheries
    ISSN 0429-9345 FAO FISHERIES 477 TECHNICAL PAPER 477 Models for an ecosystem approach to fisheries Models for an ecosystem approach to fisheries This report reviews the methods available for assessing the impacts of interactions between species and fisheries and their implications for marine fisheries management. A brief description of the various modelling approaches currently in existence is provided, highlighting in particular features of these models that have general relevance to the field of ecosystem approach to fisheries (EAF). The report concentrates on the currently available models representative of general types such as bionergetic models, predator-prey models and minimally realistic models. Short descriptions are given of model parameters, assumptions and data requirements. Some of the advantages, disadvantages and limitations of each of the approaches in addressing questions pertaining to EAF are discussed. The report concludes with some recommendations for moving forward in the development of multispecies and ecosystem models and for the prudent use of the currently available models as tools for provision of scientific information on fisheries in an ecosystem context.

For further information contact the UOW Library: [email protected] Consuming sustainable seafood: Guidelines, recommendations and realities Abstract Objective: Encouraging people to eat more seafood can offer a direct, cost-effective way of improving overall health outcomes. However, dietary recommendations to increase seafood consumption have been criticised following concern over the capacity of the seafood industry to meet increased demand, while maintaining sustainable fish stocks. The current research sought to investigate Australian accredited practising dietitians' (APD) and public health nutritionists' (PHN) views on seafood sustainability and their dietary recommendations, to identify ways to better align nutrition and sustainability goals. Design: A self-administered online questionnaire exploring seafood consumption advice, perceptions of seafood sustainability and information sources of APD and PHN. Qualitative and quantitative data were collected via open and closed questions. Quantitative data were analysed with χ2tests and reported using descriptive statistics. Content analysis was used for qualitative data. Setting: Australia. Subjects: APD and PHN were targeted to participate; the sample includes respondents from urban and regional areas throughout Australia.

  • Reproductive Biology of the Sea Cucumber Holothuria Sanctori (Echinodermata: Holothuroidea)
    SCIENTIA MARINA 76(4) December 2012, 741-752, Barcelona (Spain) ISSN: 0214-8358 doi: 10.3989/scimar.03543.15B Reproductive biology of the sea cucumber Holothuria sanctori (Echinodermata: Holothuroidea) PABLO G. NAVARRO 1,2, SARA GARCÍA-SANZ 2 and FERNANDO TUYA2 1 Instituto Canario de Ciencias Marinas, Ctra. Taliarte s/n, Telde, 35200, Las Palmas, Spain. E-mail: [email protected] 2 BIOGES, Universidad de Las Palmas de Gran Canaria, 35017, Las Palmas de G.C., Spain. SUMMARY: The reproductive biology of the sea cucumber Holothuria sanctori was studied over 24 months (February 2009 to January 2011) at Gran Canaria through the gonad index and a combination of macro- and microscopic analysis of the gonads. Holothuria sanctori showed a 1:1 sex ratio and a seasonal reproductive cycle with a summer spawning: the mean gonad index showed a maximum (3.99±0.02) in summer (June-July) and a minimum (0.05±0.04) between late autumn (November) and early spring (March). Females had significantly wider gonad tubules than males. First maturity occurred at a size of 201 to 210 mm, a gutted body weight of 101 to 110 g and a total weight of 176 to 200 g. Holothuria sanctori shows a typical temperate species reproduction pattern. These results could be useful for managing current extractions of H. sanctori in the Mediterranean and in case a specific fishery is started in the eastern Atlantic region. Keywords: Holothuria sanctori, sea cucumber, holothurians, reproduction, life-cycle, maturity, Canary Islands.

  • Consumer Preferences for Seafood and Applications to Plant-Based and Cultivated Seafood
    Literature Review Consumer Preferences for Seafood and Applications to Plant-Based and Cultivated Seafood June 2020 Jen Lamy Sustainable Seafood Initiative Manager The Good Food Institute Keri Szejda, PhD Founder and Principal Research Scientist North Mountain Consulting Group Executive Summary Plant-based and cultivated seafood can play an essential role in expanding the global supply of fish and shellfish to healthfully and sustainably meet growing global seafood demand. A key step toward accelerating the development and commercialization of these industries is understanding consumers’ relationships with seafood. This paper assesses the available literature on consumer attitudes toward seafood. The results of this review should both inform decisions on how to best serve seafood consumers with plant-based and cultivated options and inform the prioritization of further research to advance these industries. Several key results emerge from the review: Heterogeneity: ​Consumer attitudes toward seafood often vary by species, product type, and consumer segmentation. Effectively developing and marketing seafood products require understanding these variations. Motivations: ​The main motivations for seafood consumption are habit, health, and taste. Barriers: ​The major barriers to seafood consumption are price, the perception that seafood is difficult to prepare, and social settings with others who do not like seafood. Attributes:​ The key product attributes assessed by seafood consumers include freshness and country of origin, but the relative
