Extraction Method of Scallop Area from Sand Seabed Images

Koichiro ENOMOTO, Masashi TODA, Yasuhiro KUWAHARA
2014 IEICE transactions on information and systems  
In Tokoro, Japan, scallop farms are located on gravel and sand seabed. Seabed images are necessary to visually estimate the number of scallops of a particular farm.  ...  In the sand field, we can see only the shelly rim because the scallop is covered with sand and opens and closes its shell while it is alive and breathing.  ...  Acknowledgments This work was supported by JSPS Grant-in-Aid for JSPS Fellows Number 24-11059.  ...

Jasna Arapov, Daria Ezgeta-Balić, Melita Peharda, Živana Ninčević Gladan
2010 Croatian Journal of Fisheries  
Due to these process bivalves have great influence in energy and nutrient flux between benthic and pelagic communities, what makes them important part of marine food webs.  ...  Although some authors describe bivalve feeding as "automatized" process, recent studies show that some bivalves species have ability to regulate filtration and select% particles based on their size, shape  ...  INTRODUCTION Bivalves are highly abundant group of organisms in majority of costal marine environments.  ...

In the darkness of the polar night, scallops keep on a steady rhythm

Damien Tran, Mohamedou Sow, Lionel Camus, Pierre Ciret, Jorgen Berge, Jean-Charles Massabuau
2016 Scientific Reports  
In this study, we investigated the circadian rhythm of the scallop Chlamys islandica by continuously recording the animal's behaviour over 3 years in the Arctic (Svalbard).  ...  Although the prevailing paradigm has held that the polar night is a period of biological quiescence, recent studies have detected noticeable activity levels in marine organisms.  ...  These rhythms are typically invoked to increase the fitness of the animal in its environment.  ...

2014 ICES Journal of Marine Science  
Although an effect of fishing was detected, it was considered insufficient to be a limiting factor for benthic biomass.  ...  Therefore it is possible to detect and assess the effects of mobile gears on benthic communities and this is the subject of ongoing work.  ...  Appendix 2 Ecological risk screening jargon Activity = one of the activities of the agent, e.g. towing a trawl Agent of change (abbreviated to 'agent') = anything likely to be causing changes in the ecosystem  ...
