Here are also some recent project updates:
Feed fortification studies: We aim to develop an intervention based around our custom-formulated feed, which we hypothesize will improve water quality and nutrition. We are currently conducting two studies to assess this: a lab-based efficacy study (120 fishes) and a farm-based effectiveness study (12 farms). Both are progressing on track. See previous posts.
Remote Sensing of Water Quality: We aimed to develop an intervention to remotely sense (via satellites) or predict water quality. Unfortunately, our in-house modeling did not yield any viable models. We are doing some final wrap-up work, but don’t expect any breakthroughs. We expect to publish a full writeup of our results by the end of June. See previous posts.
Improved Slaughter (Chill Kill): We aim to develop an intervention that replaces air asphyxiation with immersion in an ice bath at slaughter (still causes significant suffering, but less than the alternative). Our main bottlenecks remain a) logistical feasibility, and b) trader and consumer demand. To test the former, we are planning a trial of 1,000 fishes in the coming weeks—our largest yet. See previous posts.
China Work: As part of our efforts to continue understanding and engaging the industry, we recently visited a rainbow trout farm and observed our first harvest event. We are also continuing to research interventions on various priority species, focusing on pond loach, sturgeon, and mandarin fishes.
Our staff Roshan and Gokul sampling fishes recently in the feed fortification pond-based study, in order to assess health and growth—proxies for welfare. Handling fishes in this way does cause them significant stress, but we believe the information is worth the costs (though these are tricky ethical tradeoffs that we sometimes struggle with).
