Salmon question

[Tango451]

Usually I get fresh sock-eye salmon to feed anemones and it never has a smell or one I can detect.

Today I got fresh keta aka chum salmon, and it has a sweet shellfish kind of smell almost like lobster. I've never smelled salmon like thiis before as it either has no smell or it smells bad.

Would you deem this safe to feed carpets or is it bad? (color of salmon is good, feels firm, not mushy etc but the lobster like sweet smell is throwing me off)


Also on a side note, why would an established carpet that's been with someone for years and now 8 months in a new system get suddenly darker (from red to more dark red/a little brown). No changes in lighting in 8 months etc.

I would not feed anything that does not smell right. I would also switch to saltwater fish vs salmon.

Your new tank is probably rich in nutrients, hence the change in color. New tanks usually go through a cycle around 1-year mark, so keep an eye on the parameters.

Salmon is a saltwater fish. I feed it to my nems all the time, and it's my food of choice.

When I read up on Keta salmon it sounds like it's considered sub-par against other species of salmon. The consistency of fish varies a lot in terms of flesh color, texture, and oil content. In other words, it's a cheaper salmon from a consumer view, but should be fine to feed your nems assuming it was handled correctly.

That said, if it smells at all, I would pass on feeding it to your nems. Not worth your investment in nems when there are other food options (or not feeding it at all).

Depends on the species. Furthermore

The sub-sector of salmon farming in saltwater is a minor part of the national aquaculture industry, but it is a valuable economic asset contributing 11% to the total value of all aquaculture products. Only 45 commercial farms produce salmonids in marine net-pens directly for food, which is just 1% of all production facilities registered in the country, and <6% of all facilities in marine and coastal waters. Another 244 federal, state, or tribal facilities in the freshwater environment produce anadromous Pacific and Atlantic salmon for restoration of the commercial fisheries, recreational fisheries, or conservation, and another 362 freshwater facilities produce salmonids for both food fish and recreational fisheries. Because of its particular niche in marine and coastal waters, American net-pen technology has resulted in considerable growth of secondary producers in the aquaculture industry, and contributes a disproportionate share to the export of national goods and services.

Very few. The vast majority of salmon you would find in the grocery store, in fact ALL the salmon in the stores in the pacific NW, are saltwater salmon. There are a very rare few types of salmon that live exclusively in freshwater: Kokanee, Landlocked Atlantic, Danube, off the top of my head.

All the other salmon live the vast majority of their lives in the ocean. They hatch in freshwater, head out to the ocean for 4-6 years, return to fresh to spawn and then turn around and head back to the ocean. Unfortunately the freshwater is not suitable for them at this stage and they die on the return trip to the ocean. You see them literally rotting away as they try to swim back.

To the OP, if you are concerned, don't feed it. As an avid salmon fisherman, what you are describing doesn't sound like rotting salmon.

Why not just feed silversides?

I tend to ignore farm-raised salmon. Wild only when feeding my nems. Furthermore, the term "anadromous" refers to fish that travel from the sea (saltwater) to freshwater spawn. They spend the majority of their lives in the ocean.

Agreed. For purposes of this discussion it's safe to say that salmon are saltwater fish.

Why not just feed silversides?

Silversides have been blamed for the death of many anemones. They aren't considered human grade food so they aren't under the same scrutiny. They may have been thawed or even allowed to spoil and are then re-frozen and we'd never know. Best to stick with fresh seafood.

 

[Potatohead]

Salmon at least around here only live in freshwater when they are hatched and when they go back to the same spot they are born to breed, and then die. Otherwise they are totally saltwater.

 

[Cabo31]

Salmon also live in the Great Lakes never seeing saltwater their entire life

Why not just feed silversides?

I would avoid feeding silverside or any food prepared for aquarium (pet food) to my anemones. Pet food have much higher risk of being spoiled because care for pet food (shipping and at the LFS) just not as stringent as for human food. Siverside being small fish frozen with their guts intact can spoil very easy. Eating spoiled food will result in death of the anemone. This is a common cause of "mysterious anemone death". I feed food for human consumption, free of additive, to my anemone only. If the food seem "funny" for any reason, it is not used.

OP, if the food is not right in your opinion, don't use it. I feed wild caught Salmon and Tuna to my anemone exclusively, plus other than the fish I caught fishing in the Corpus Christi bay or Gulf of Mexico. Salmon is very fatty, it tend to leave a fatty film on top of my water for a few mins then clear by my filtration system.
