چکیده

The aim of this study was to develop a pilot plant for the production of M. barbatus seed through artificial reproduction technology for possible use in aquaculture and repopulation of nursery areas. The study involved various phases: setup of the pilot plant, sourcing of M. barbatus specimens and their transplantation to an offshore long-line farm; production of live food (phytoplankton); selection of broodstock; artificial reproduction in a controlled environment and larval and post-larval feeding in the pilot plant; refinement of the offshore farming technology and evaluation of yield on the long-lines with respect to the various production systems used and the different line depths. The specimens of M. barbatus raised on long-lines gave a good yield. The results of both the stimulation and larval farming confirm the applicability of the techniques described in the literature. Encouragingly, the daily mortality was lower than results reported to date (7.9%).

Metabolic and molecular stress responses of sublittoral bearded horse mussel Modiolus barbatus to warming sea water: implications for vertical zonation.

The present study set out to investigate the thermal limits of the Mediterranean bivalve Modiolus barbatus, acclimated to various temperatures, and includes a comparison of laboratory determined limits with its temperature-dependent restriction to deeper water layers in its natural habitat. Thermal responses and limits were determined by integrating information from various levels of biological...

An energy budget for the subtidal bivalve Modiolus barbatus (Mollusca) at different temperatures.

Clearance rates, respiration rates and food absorption efficiencies of the commercially interesting subtidal bivalve Modiolus barbatus were measured at different temperatures under laboratory conditions and scope for growth calculated. Clearance rates were highest at temperatures from 20 °C to 28 °C, whereas respiration rate was maximal at 9 °C and minimal at 26 °C. Highest mean values of absor...

Mussel attachment on rocky shores: the effect of flow on byssus production.

Mussels rely on a strong byssal attachment to persist in a range of habitats with differing rates of water flow. Recent studies, however, suggest that the ability of one mussel species to sense and respond adaptively to the flow in its environment is limited under even modest flow conditions because the process of byssal thread formation is disrupted. This study extends these findings to four m...

Interspecific comparison of the mechanical properties of mussel byssus.

Byssally tethered mussels are found in a variety of habitats, including rocky intertidal, salt marsh, subtidal, and hydrothermal vents. One key to the survival of mussels in these communities is a secure attachment, achieved by the production of byssal threads. Although many studies have detailed the unique biomechanical properties of byssal threads, only a few prevalent species have been exami...

Melanin-based color variation in the Bearded Vulture suggests a thermoregulatory function.

We document a case of intraspecific variation in plumage colouration in Bearded Vultures that may have arisen as a functional response to climate conditions. Two subspecies, Gypaetus barbatus barbatus (Eurasia and North Africa populations) and Gypaetus barbatus meridionalis (Eastern and Southern Africa), have been described on the basis of plumage colour differences. The plumage of G. b. barbat...
