The R/V Kaho, based in Oswego, New York, was built in 2011 and currently operates on Lake Ontario. The new Kaho replaced the original R/V Kaho (built in 1961), which was the workhorse of the multiagency fisheries research fleet on Lake Ontario for more than three decades. The new Kaho participates in long-term data collections including population studies of prey fish and stocked lake trout, fish and environmental sampling for contaminants monitoring, and documentation of changes in food webs and fish distributions associated with invasive species. The Kaho can be at sea five days with sleeping accommodations for six people. The Kaho has a full galley and two heads, one with a shower.
