    Description / Table of Contents: The aim of this book is to review and analyse the goods and services of bivalve shellfish. How they are defined, what determines the ecological functions that are the basis for the goods and services, what controversies in the use of goods and services exist, and what is needed for sustainable exploitation of bivalves from the perspective of the various stakeholders. The book is focused on the goods and services, and not on impacts of shellfish aquaculture on the benthic environment, or on threats like biotoxins; neither is it a shellfish culture handbook although it can be used in evaluating shellfish culture. The reviews and analysis are based on case studies that exemplify the concept, and show the strengths and weaknesses of the current applications. The multi-authored reviews cover ecological, economic and social aspects of bivalve goods and services. The book provides new insights for scientists, students, shellfish producers, policy advisors, nature conservationists and decision makers. This book is open access under the CC BY license

    Seawater carbonate chemistry and post-larval growth and metabolism in two populations of the great scallop (Pecten maximus L.) (2023)
    PANGAEA
    Details
    Publication Date: 2024-03-15
    Description: We carried out a common garden experiment to investigate how different populations of the economically important great scallop (Pecten maximus) from France and Norway responded to variation in temperature and pCO2 concentration. After acclimation, post-larval scallops (spat) were reared for 31 days at one of two temperatures (13°C and 19°C) under either ambient or elevated pCO2 (pH 8.0 and pH 7.7). We combined measures of proteomic, metabolic, and phenotypic traits to produce an integrative picture of how physiological plasticity varies between the populations.

    On the relationship between low winter temperatures and mortality of juvenile scallops, Pecten maximus L., cultured in western Norway (2003)

    Notes: The mortality of juvenile scallops (Pecten maximus L.) cultured at two densities at 8- and 15-m depth was investigated at 17 trial locations along the western Norwegian coast between latitudes 58 and 65°N. During the winter of 1995/1996, scallops suffered high mortality at many sites. The results show a clear relationship between minimum temperature recorded on the sites and scallop mortality. All the scallops died at sites where minimum temperatures were lower than 2°C, while a mortality rate below 30% was only obtained at locations where the minimum temperature was 4–5°C. At temperatures between 2 and 4°C, mortality was intermediate, ranging from 52% to 100%. There were no mortality differences between culture densities, while a significantly higher mortality at 8- than at 15-m depth was shown for two of the four sites with a total mean mortality lower than 30%. The results are discussed in relation to low-temperature conditions along the Norwegian coast to suggest risk assessments for site selection in scallop culture.

    Notes: We investigated handling time, persistence time and shell-breaking techniques by crab, Cancer pagurus (L.) (13–15 cm carapace width), offered cultured scallops, Pecten maximus(L.), within the recommended release size for bottom culture. Three shell height groups were used: 50–55, 60–65 and 70–75 mm. The results showed that the crabs managed to open scallops from all the three size groups. The median handling time in the 50–55 mm group (788 s) was significantly different from the median handling time of the 60–65 mm (2482 s) and 70–75 mm (2980 s) groups. The median persistence time increased significantly with each scallop size, from 89 s in the 50–55 mm group to 97 s in the 60–65 mm and 125 s in the 70–75 mm group. We observed a change in the shell-breaking techniques from a dominance of smashed scallops in the 50–55 mm group to more punched and chipped scallops in the 60–65 and 70–75 mm groups. The shift in predation behaviour when crabs were offered 50–55 mm scallops compared with the larger groups is discussed in relation to strategies in the release of scallops to seabed cultures.

    Notes: Abstract Scallop spat produced for continued culture normally requiretransportation between sites, and the associated stresses may causemortalities. In the present experiment, scallops of 40–55 mm shell heightwere emersed in air for time intervals up to 24 h and their behaviourexamined once re-immersed. Scallops were placed upside-down and thenumber of movements and the cumulative numbers righting in 5 min timeblocks were recorded. The greatest frequency for all behaviouralresponses was found at 15–17 °C in August. Responses were reducedin November and June (9–11 °C) and least at 5 °C in January.All effects of treatment, temperatures and season, and increases in airexposure were significantly different. Following the treatments, mortalitiesafter 10 days in culture was about 10–30% for scallops emersed for 18 and24 h in August and June. Scallops did not show significantly differentbehaviour whether they were emersed upright or inverted. However,scallops emersed at 15 °C had fewer responses than scallops held at 〈10 °C, so chilling during transport may prolong scallop vitality. Theresults suggest that air exposure 〉12 h should be avoided. At temperatures〉9 °C, behavioural responses may be a simple and effective method toassess vitality which can assist in the management of scallop culture.

    Mussels or tunicates: That is the question. Evaluating efficient and sustainable resource use by low-trophic species in aquaculture settings (2019)
    Elsevier
    In:  Journal of Cleaner Production, 231 . pp. 132-143.

    Description: The growing demand for aquaculture products can only be maintained by increasing the production of lower trophic species such as bivalves and tunicates. Low trophic species avoid the energy losses during trophic transfers to build animal protein, making them ideal candidates to exploit available resources in coastal waters. In the particular case of fjords, forced upwelling of deep nutrient-rich waters can promote phytoplankton growth, or in other words, the growth of bivalve and tunicate food. However, the density at which bivalves and tunicates are cultured can compromise phytoplankton populations and consequently, marine food chains. A highly configurable environmental model was constructed to study the ecosystem effects and potential biomass production of hypothetical bivalve and tunicate aquaculture scenarios in a Norwegian fjord under forced upwelling conditions. The simulations objectively determined the level of aquaculture development that maximizes the sustainable utilization of resources towards bivalves and tunicates biomass production. The model also highlighted the positive effect of the forced upwelling on both cultured production and phytoplankton abundance under aquaculture scenarios. Finally, the model predicted that tunicates would be more efficient than mussels at extracting resources due to their lower metabolic cost and higher filtration capacity. Although a full economic analysis would be required to decide on the preferred species to be cultured, these results encourage current pilot studies in which tunicates are explored as a sustainable way to efficiently exploit marine resources for aquafeed production.
