The West Coast fishery managers put it to a vote; suffer now or maybe suffer forever. They voted on Thursday to ban salmon fishing for one year hoping a rest will allow the salmon population to recover along the Oregon and California coast.
Two years ago the salmon catch was only at 80% of normal and the Commerce Department estimated the losses then at $16 million. This year with the catch being 0% of normal the losses will be unthinkable.
The loss of the king salmon is being billed as the “catastrophic disappearance” of the famous fish.
6 years ago the Sacramento River and tributaries had more than 800,000 salmon spawning. The predictions for this coming fall are a frightening 50,000. The reason for the vanishing king salmon (chinook) could be a ’sudden lack of nutrient-rich deep ocean upwellings. The sudden lack is thought to be caused by ocean temperature changes.
The decline in the salmon isn’t something that happened overnight in spite of the sudden lack of upwelling. There can be problems in the ocean that affect the salmon populations, or problems in the rivers that do the same. This year there are problems in both and that spells catastrophic.
As gas reaches $4.00 a gallon in the U.S. a lovely salmon entree any favorite eatery could reach $40.00 a portion.
This has to be good news for the salmon aquaculture business. For the consumer trying to stay clear of Malachite Green, Ciprofloxacin and Enrofloxacin just to name a few known toxins in aqua-farmed fish this ban on salmon fishing is bad news.
The list of reasons for the down turn in salmon populations could be a foot long. For years juvenile salmon have been turning up in irrigation ditches and in some cases dead juveniles have turned up in fields that are irrigated by those ditches. The laws requiring screens that hold back young salmon have not been enforced and the regulations are not uniform.
Diseases that spread quickly through high density farmed salmon populations can spread to adjacent waters. Some salmon often escape and compromise nearby native salmon habitat.
This news release from the Pacific Fishery Management Council indicates just how bad the situation really is for the salmon population. It also indicates this news came rather suddenly after a very successful rehabilitation of the Chinook previously known as the “work horse”.
