From the Preparedness Blog Network: How To Salt Fish.
I recently came across a cookbook from the 1850s. That cookbook is very interesting covering all types of pioneer cooking. One of the articles covers the preserving of shad, a type of fresh water fish. The recipe used for shad can be used for any fish.
The following recipe is taken directly from the cookbook.
"Clean the shad nicely, place them in layers with back down, and laid open so as the inside of the fish may be up. Sprinkle each fish plentifully with ground salt, and let them stand twenty four hours. This draws out all the blood. Wipe them all dry with clean napkins.
Place them in layers in a clean tub, with the backs down as before. For one hundred shad take half a lb. saltpetre, and 2 pounds of brown sugar. Strew plenty of rock salt over them with the saltpetre and sugar, there is no danger of putting on too much salt as they will only absorb a certain quantity."
As you can see, this is a very simple recipe. You will notice this recipe uses quite a bit of salt, I strongly recommend that everybody store at least 100 pounds of salt, if you intend to do any food preserving. Saltpeter or saltpetre is commonly known as potassium nitrate.
Do old fish behave differently than middle-aged fish?
Not only can they behave differently, they can look different too. Some fish will move more slowly, some fish may appear to be "resting" more often. Some fish colors become more vivid with age, some fade with age. Some loose their markings with age, and others develop other markings as they age.
So it's not really easy to answer that question when talking about all fish. When talking about a specific fish it's easier to answer.
Plankton refers to a diverse group of microscopic organisms that drift in aquatic environments, including both freshwater and marine ecosystems. They are classified into phytoplankton (plant-like organisms that perform photosynthesis) and zooplankton (tiny animals that feed on phytoplankton or other small organisms). Plankton play a crucial role in the food web, serving as a primary food source for many larger organisms, including fish and whales. Their abundance and diversity are vital for maintaining ecological balance in aquatic habitats.
The reason why fish have silver skin is because it helps them to hide from predator. The silver skin refracts light and makes it harder for enemies to see these fish.
I am not sure but I think they eat baits. Look it up in the internet to make sure. I hope that helps.
Does my fish need light to survive or become healthier?
Most fish prefer to live in a well-lit tank. Lighting enhances the colours, and also allows live plants to grow, and fish prefer living in an environment with live plants. Fish constantly kept in the dark will probably be stressed and their eyesight may be affected.
Why do fish produce very large number of young?
The main reason that fish produce a very large number of young is because of predators. They also produce a large number of young because many die during the early stages of life.
There is no set size to a school; but there is always 3 or more (2 would be a pair of fish), and schools can be massive and contain thousands of fish.
