Phaeocystis antarctica , a dominant phytoplankton species found in the Southern Ocean, is known for colony formation and large seasonal blooms. Blooms play a key role in Southern Ocean biogeochemistry, contributing to carbon export and the production of dimethylsulfoniopropionate (DMSP) and its climatically active breakdown product, dimethyl sulfide (DMS). Here we provide evidence of phagotrophy, i.e., mixotrophic behavior in...

The current generation of sequencing technologies can produce terabases of data with exceptional accuracy and speed, at a fraction of the cost of older methods. Despite this unprecedented power, adoption into aquaculture health management presents several challenges, including identifying where such capability may be optimally deployed. Here we synthesise discussions from a structured expert workshop held at the 2025 Aotearoa...
