Algal bloom kills 250,000 salmon in Canada

News reproduced from

“Grieg Seafood has experienced acute mortality at two of its BC locations in the Jervis Inlet following harmful algal blooms (HAB) in the area. Total mortality is estimated to 250,000 fish or approximately 1,000 tons. This represents some 50 percent of the total biomass from the two locations.

Grieg Seafood continuously works to improve biosecurity and all of Grieg Seafood’s sites perform algal monitoring by taking daily samples which are analyzed using advanced image analysis techniques. This allows for the identification of the species, prevalence and depth distribution of any algae present.

The HAB in Jervis consisted of Heterosigma, a species of microscopic algae that cause acute mortality in fish. Due to extraordinarily high concentration and spread throughout the entire water column, use of Aeration treatments or other protective measures could not prevent the incident.

Grieg Seafood has insurances covering such incidents, and estimated costs including individual share of insurance are limited to NOK 25 million. The costs will be charged the Q2 2018 results”.

New research links neonatal exposure to BMAA in a rat model with neurodegenerative diseases

A new paper published by Laura Louise Scott and Timothy Grant Downing of the Nelson Mandela University in South Africa, presents results about the selective toxicity of BMAA during neurogenesis in the rodent brain.  The authors have observed neuropathological symptoms typically associated with Alzheimer’s Disease, Parkinson’s Disease  and Amyotrophic Lateral Sclerosis following a single BMAA neonatal exposure. It is suggested that BMAA elicits its effect by altering dopamine and/or serotonin signaling in rats.

WRF webcast: Development of a Risk Communication Tool Kit for Cyanotoxins (June 27, 2017)

Water Research Foundation (WRF) webcast:

Development of a Risk Communication Tool Kit for Cyanotoxins

Tuesday, June 27th, 2017
3pm-4pm ET
(2pm-3pm CT, 1pm-2pm MT, 12pm-1pm PT)

Do you need to communicate the potential risk of cyanotoxins in drinking water? While some communication tools and resources for utilities have been developed, utilities and the customers that they serve need additional targeted messages and materials. This webcast will discuss the findings of WRF project #4697, Development of a Risk Communication Toolkit for Cyanotoxins. Listeners will learn about specific attributes of the cyanotoxin risk management framework that can create potential communication barriers, for example the complexity of the EPA health guidance and the uncertainty inherent in monitoring and testing timing and protocol. Listeners will also be introduced to the linguistic research carried out during the project, which was used to develop recommended health advisory/alert language. This Webcast is designed to provide listeners with the necessary knowledge to develop and deliver effective cyanotoxin risk communications.

CYANOCOST’s Annick Wilmotte in Chile

Annick Wilmotte, of the Univesity of Liege, Belgium, will give a lecture on the molecular approaches to cyanobacterial taxonomy and ecology (Aproximaciones taxonómicas y moleculares a la taxonomía y ecología de cianobacterias) in a Summer School organised by the Environmental Sciences Center (EULA) of the University of Conception, Chile. Annick has an outstanding research career especially on Antarctic cyanobacteria with great achievements and awards, including  a cyanobacterial genus named after her.

Annick will briefly present CYANOCOST to colleagues from Chile, who are welcome to join the network.
