Fish and Watersheds

In recent weeks, Hyacinthe Creek – one of a handful of  salmon bearing streams on Quadra Island – has experienced a few salmon swimming up its waters. Their arrival has not been an easy journey!

Life for all adult salmon, for millennia, has been a series of survival challenges. Depending upon the species, life cycles range from 2 years (Pinks) to 7 years (Chinook). For new born salmon referred to as fry, making it from their Coastal and or Interior BC birth streams to salt water can require many weeks to months of learning what to eat, while being swept over waterfalls to then crash through rapids for many more kilometers downstream.

Fish farms underreport sea lice when not being audited, study says

“Our results suggest that sea-louse counts reported by the salmon farming industry are lower than the true abundance of parasites on their fish. When the federal government audited a sea-louse count, the industry’s mean counts for that month increased by a factor of 1.18 for L. salmonis and by 1.95 for C. clemensi.” – Sean Godwin et al, Bias in self-reported parasite data from the salmon farming industry.

Dr Sean Godwin is the lead author of eight of the fifteen scientific papers listed on his website. The bulk of these explore interactions between wild and farmed salmon. One of the most troubling, published in the journal Ecological Application, is a survey that showed fish farms underreport sea lice when they are not audited by Fisheries and Oceans Canada.
