The Good Practice Guide to Handling and Storing Live Crustacea The Good Practice Guide to Handling and Storing Live Crustacea Research and Development, Seafish Author: Marcus Jacklin, Jason Combes This project is part-financed by the European Union through the Financial Instrument for Fisheries Guidance (FIFG), the structural fund for fisheries. FIFG aims to maintain a dynamic and competitive fishing industry and revitalise areas dependent on fishing. It is administered in the UK by the Department for Environment, Food and Rural Affairs (Defra). The Good Practice Guide to Handling and Storing Live Crustacea Summary Seafish has an ongoing programme to produce good manufacturing practice guidelines (GMP) for the fishing and related industries. These GMP guidelines have been produced for commercial operatives engaged in handling and storing live crustacea within the United Kingdom. They aim to help businesses achieve high standards of operation by encouraging practices that ensure product safety, product quality, and efficient use of resources. The advice has been produced in collaboration with the industry and appropriate regulators. The guidelines are relevant to sectors that handle live crustacea from capture to the point of dispatch (primary producers). They cover activities aboard vessels, at live holding premises ashore and during ‘vivier’ transportation. The use of this guide by fishermen is voluntary and it does not have legal status. The guide describes relevant legal requirements and some interpretation may be included; however, they do not absolve the Trade from the law. The information in it will help fishermen meet their legal obligations, and ensure the safety of the fish they land. The advice is for guidance and information purposes only; the document is not intended to be used as a formal training manual. This project has been part financed by EU FIFG (Financial Instrument for Fisheries Guidance) delivered through the Scottish Executive and administered by Seafood Scotland. i © Seafish A Practical Guide to Handling and Storing of Live Crustacea Table of Contents: Summary 1.

Seafood Watch® defines sustainable seafood as originating from sources, whether wild-caught or farmed, which can maintain or increase production in the long- term without jeopardizing the structure or function of affected ecosystems. Seafood Watch® makes its science-based recommendations available to the public in the form of regional pocket guides that can be downloaded from the Internet (seafoodwatch.org) or obtained from the Seafood Watch® program by emailing [email protected]. The program’s goals are to raise awareness of important ocean conservation issues and empower seafood consumers and businesses to make choices for healthy oceans. Each sustainability recommendation on the regional pocket guides is supported by a Seafood Report. Each report synthesizes and analyzes the most current ecological, fisheries and ecosystem science on a species, then evaluates this information against the program’s conservation ethic to arrive at a recommendation of “Best Choices”, “Good Alternatives” or “Avoid.” The detailed evaluation methodology is available upon request. In producing the Seafood Reports, Seafood Watch® seeks out research published in academic, peer-reviewed journals whenever possible. Other sources of information include government technical publications, fishery management plans and supporting documents, and other scientific reviews of ecological sustainability.

ZooKeys 935: 25–35. https://doi. org/10.3897/zookeys.935.51931 Abstract Hendersonida parvirostris sp. nov. is described from Papua New Guinea. The new species can be distin- guished from the only other species of the genus, H. granulata (Henderson, 1885), by the fewer spines on the dorsal carapace surface, the shape of the rostrum and supraocular spines, the antennal peduncles, and the length of the walking legs. Pairwise genetic distances estimated using the 16S rRNA and COI DNA gene fragments indicated high levels of sequence divergence between the new species and H. granulata. Phylogenetic analyses, however, recovered both species as sister species, supporting monophyly of the genus. Keywords Anomura, mitochondrial genes, morphology, West Pacific Introduction Squat lobsters of the family Munididae Ahyong, Baba, Macpherson & Poore, 2010 are recognised by the trispinose or trilobate front, usually composed of a slender rostrum flanked by supraorbital spines (Ahyong et al.

For over 140 years, convergent evolution of the crab-like body plan (with a wide and flattened shape, and a bent abdomen) at least five times in decapod crustaceans has been known as ‘carcinization’. The repeated loss of this body plan has been identified as ‘decarcinization’. We offer phylogenetic strategies to include poorly known groups, and direct evidence from fossils, that will resolve the pattern of crab evolution and the degree of phenotypic variation within crabs. Proposed ecological advantages of the crab body are summarized into a hypothesis of phenotypic integration suggesting correlated evolution of the carapace shape and abdomen. Our premise provides fertile ground for future studies of the genomic and developmental basis, and the predictability, of the crab-like body form.

Michel Francois Marie Bermudes Abstract The aim of this project was to define more clearly the culture conditions for the propagation of the southern rock lobster (Jasus echvardsii) in relation to environmental bioenergetic constraints. The effects of temperature and photoperiod on the first three stages of development were first studied in small-scale culture experiments. Larvae reared at 18°C developed faster and reached a larger size at stage IV than larvae cultured at 14°C. Development through stage II was shorter under continuous light. However, the pattern of response to photoperiod shifted at stage III when growth was highest in all the light/dark phase treatments than under continuous light. The influence of temperature and light intensity in early-stage larvae was further investigated through behavioural and physiological studies. Results obtained in stages I, II and III larvae indicated an energetic imbalance at high temperature (-22°C).

  • Seasonal Variation in Community Structure and Recruitment of Benthic Decapods in a Sub-Tidal Cobble Habitat
    MARINE ECOLOGY PROGRESS SERIES Vol. 206: 181–191, 2000 Published November 3 Mar Ecol Prog Ser Seasonal variation in community structure and recruitment of benthic decapods in a sub-tidal cobble habitat Martin Robinson*, Oliver Tully Department of Zoology, Trinity College, Dublin, Ireland ABSTRACT: Quantitative suction samples of benthic decapod fauna were taken in the south of Ireland during 1997. Some species settled into the area, but failed to persist to the first winter, while others were present in high numbers throughout the year. The duration of settlement was species- specific, ranging from several weeks to several months. Body size at settlement decreased with increasing temperature during larval development. Growth potential and early mortality of a number of decapod species was examined by separation of successive moult instars from length-frequency distributions. Seasonal lows in abundance and biomass of young of the year and for previously estab- lished decapod individuals were identified at the end of July and early August, which may represent the most suitable time to release juveniles for stock-enhancement purposes. Community structure differed between settlement season and over-wintering periods. Young-of-the-year community structure differed from that of previously established individuals, with higher abundance and num- ber of species recorded for the former. The data represent a baseline study of a widely distributed community and may support further work on species interactions, improving the accuracy of predic- tion of annual recruitment fluctuations.
