FlowCam^® - Flow Imaging Microscopy Blog

In order to reduce unnecessary travel and keep our team safe,  we have canceled our foreseeable conference appearances. In lieu of attending the Annual Meeting of the National Shellfisheries Association this month, they have provided us a platform to tell the story of the FlowCam and how it can benefit the Shellfish Aquaculture Industry. What follows below is taken from their quarterly newsletter and explains how the new FlowCam 5000 can support this industry.

Aker BioMarine (ABM) is a biotech, fishing, marine research and krill harvesting company. They recently purchased a FlowCam for use on their krill harvesting vessel, the Antarctic Endurance.  They plan to use the FlowCam to monitor the phytoplankton that the krill eat, in order to maintain a sustainable krill fishery.  

Nick Ray (PhD Candidate) and Gretchen McCarthy (Senior) from the Boston University Marine Program (BUMP) came to visit our FlowCam lab in Scarborough this week. Nick Ray had used a FlowCam in 2016 in Dr. Robinson Fulweiler's lab when he was a recipient of our Student Equipment Grant. Gretchen has worked in this lab since she was a freshman. She's planning to begin graduate school next year and will focus her studies on fisheries and aquaculture.

In the Austral Summer of 2018-2019 a Norwegian research group aboard the RV Kronprins Haakon, an ice-breaking polar research vessel, traveled to the Antarctic on a research mission with two objectives: 1) to update the estimate of biomass and distribution of krill off the coast of West Antarctica and 2) to become educated on the marine environment in this area for the purpose of implementing a Feed-Back Management (FBM) system, allowing fishery managers to set catch limits based on current ecosystem health.

In 2016, 23 million salmon died from a harmful algal bloom (HAB) at a farm in Chile.  The economic cost of  that die-off is estimated to have been $800 million.  The impact of such mortality events is serious.  Grieg Seafood is employing cutting-edge technology to expand monitoring, stay ahead of HABs, and keep their fish stocks healthy.

Nicholas Ray, PhD candidate at Boston University, was the 2016 recipient of the Fluid Imaging Technologies student research grant program.  Applicants submit proposals for how they intend to use the FlowCam within the scope of their research, and the winner is awarded the use of a FlowCam for a 4-month period. Fluid Imaging Technologies also provided Ray with a paid registration to the 2017 Coastal & Estuarine Research Federation (CERF) Conference where he gave an oral presentation on his research. 

Historically, Grieg Seafood has relied upon manual microscopy to identify and count algae as they monitored for HABs and to determine if there was a need to employ mitigation strategies. On any given day, there could be upwards of 100 species of algae, and using manual microscopy can be like trying to find a needle in a haystack. The quality of the analyzed data is not consistent, and the process is prone to error.

Grieg Seafood plans to use the FlowCam to make more informed decisions around HAB monitoring. They have the experience and the judgment to make the right calls. What they need is more data.

SCARBOROUGH, Maine - June 7, 2016 - Laboratory instrumentation manufacturer Fluid Imaging Technologies, Scarborough, Maine has awarded its 2016 Aquatic Research Student Equipment and Travel Grant to Nicholas Ray, Ph.D. student, Boston University, Department of Biology, Boston, Massachusetts under the supervision of Dr. Robinson Fulweiler. His proposal, Bivalve Control of Coastal Phytoplankton Communities, was selected after a series of in-depth reviews by a panel of independent aquatic scientists. Judging criteria included scientific merit, appropriate use of the FlowCam® and the ability to obtain measurable results during a research period of four months.
