An investigation into the efficacy of Biokos® in controlling ciliates in laboratory cultures of Saccharina latissima gametophytes. [PDF]
J PhycolAbstract A major challenge faced by kelp aquaculture operations is the control of contaminants, including by marine ciliates. Biokos® is a commercially available treatment for ciliate parasites in fish, in which the active ingredient is a viscosin‐like lipopeptide surfactant.

Exploring indirect effects of a classic trophic cascade between urchins and kelp on zooplankton and whales [PDF]
Scientific ReportsKelp forest trophic cascades have been extensively researched, yet indirect effects to the zooplankton prey base and gray whales have not been explored. We investigate the correlative patterns of a trophic cascade between bull kelp and purple sea urchins

Ammonification by kelp associated microbes increases ammonium availability. [PDF]
PLoS ONEMicrobes contribute biologically available nitrogen to the ocean by fixing nitrogen gas from the atmosphere and by mineralizing organic nitrogen into bioavailable dissolved inorganic nitrogen (DIN). Although the large concentration of plants and algae in

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.We found that urchin culling and kelp seeding interventions can be effective at rebuilding kelp forests, but require intensive effort (e.g. removing 25%–50% of urchins over multiple years), especially in the absence of predators. Our results provide recommendations for the magnitude and timing of culling and seeding that would be needed to provide ...

Bull Kelp (Nereocystis luetkeana) enhancement plots in the Salish Sea
, 2018 Data regarding the abundance of bull kelp (Ne-reocystis luetkeana) along the east coast of Vancouver Island in British Columbia is lim-ited, but there is evidence that bull kelp popu-lations have been in steady decline within the central Strait of Georgia within recent decades (Lamb et al., 2011).

Star Power: Early life stages of an endangered sea star are robust to current and near-future warming. [PDF]
PLoS ONEThe sunflower star, Pycnopodia helianthoides, was a top benthic predator throughout its former range from Alaska to northern Mexico, until its populations were devastated starting in 2013 by a disease known as seastar wasting.
