Why does the coast of Vancouver Island turn turquoise every spring? | Herring spawn explained

The coast of Vancouver Island turns a bright turquoise blue every spring. But why? It’s fish sperm, or milt, from the herring spawn. This annual breeding event happens for millions of Pacific herring, a small fish that is at the foundation of B.C.’s marine ecosystem. This natural spectacle attracts wildlife in huge numbers to gorge on the fish and eggs.
Connel Bradwell and Emily Robertson are on the coast of Vancouver Island to explore how the herring spawn is key to healthy wildlife populations.

The spring of 1991 had a huge herring run into False Creek in Vancouver. We had just painted the bottom on our sailboat with antifouling paint. Unfortunately this killed the roe and I spent an afternoon scraping 2 to 3 cm of dead roe off the bottom. The millions and millions of roe on all the pilings and other boats hatched and swam away leaving clean surfaces.

Do our thoughts influence nature?
Indeed, our thoughts influence nature.
We live in a single global-integral system of nature, we influence it with our thoughts, and we receive feedback accordingly.
Similar to laws that operate on mechanical, electronic, electromagnetic and other material and biological scales, when we press, push or constrain something, we receive a response. Likewise, when we think positively or negatively about others, we accordingly receive a response.
The global-integral reality in which we live is a closed system, and we receive responses from it according to our attitudes to it.

So when herring release their sperm into the water it’s called “the northern lights of the ocean” but when I do that at the public pool it’s called “a breach of my probation”🤔😤
