Common types of natural foods in trout farming

Plankton that grow naturally in the water and is cultivated by fertilization is an excellent natural feed for salmon. Plankton floats in the water and lives in small individuals. It is generally difficult to see with the naked eye and can only be clearly observed under a microscope. Can be divided into two major categories of phytoplankton and zooplankton.

I. Phytoplankton

Phytoplankton is the original producer in the natural water body. It absorbs nutrients such as nitrogen, phosphorus and potassium and carbon dioxide in the water, and uses light energy to carry out photosynthesis and can multiply, becoming the most basic bait resource in the water area. In general, nitrogen, phosphorus, potassium and other nutrients in high water content, phytoplankton biomass is high, fish production is also high.

Different types of phytoplankton have different bait values. Since salmon and other fish do not digest fibrous matter, pectin, chitin, etc., it is difficult to use most of the cyanobacteria, cell senescent green algae, and euglena. Can better digest and use such as gold algae, Cryptophyta, diatoms and some dinoflagellates, yellow algae, green algae, Euglenophyta, Cyanophyta and so on.

Second, zooplankton

It feeds primarily on phytoplankton and organic debris and is a consumer in the waters. Its individual is much larger than phytoplankton, but it generally does not exceed 5 mm. In addition to the main plankton life, many species can also run benthic life. Zooplankton are part of carp feeding, and they are generally used as the main foodstuff during the young fish stage. The main categories are protozoa, rotifers, Cladocera and copepods.

1. Protozoa: Protozoa are single-celled animals that have no tissue or organ differentiation but have respiratory, excretory, reproductive, and sensory functions.

2. Rotifers: Rotifers are filter feeders and feed on planktonic algae, protozoa, bacteria, and organic debris. It is very adaptable and can survive in all types of waters, especially in artificially fertilized ponds, reservoirs and river channels. It is a palatable bait for various fish juvenile stages.

3. Cladocera: Cladocera commonly known as leeches, also known as red worms. Cladocera widely distributed in lakes, ponds, reservoirs and other bodies of water, mainly filter bacteria, unicellular algae and organic debris, rapid growth and reproduction, high nutritional value, is the main bait of clams. In areas where there are a large number of clumps, fish production is generally high.

4. Copepods: Small crustaceans, such as sword water scabs and dart water scoops, are called copepods. They eat mostly floating plankton algae and are good foods.

In addition to filter plankton in filter water, carp also filters organic rot.

Nerve System

For the treatment :

[Of all the diseases of the nervous system, the most common difficulty that people have is pain, and much of that is nerve-related," according to Dr. Shai Gozani, founder and CEO of NeuroMetrix, a medical device company. [There are 100 million people who live with chronic pain."


According to the Mayo Clinic, patients with nerve disorders experience functional difficulties, which result in conditions such as:


Epilepsy, in which abnormal electrical discharges from brain cells cause seizures

Parkinson's disease, which is a progressive nerve disease that affects movement

Multiple sclerosis (MS), in which the protective lining of the nerves is attacked by the body`s immune system

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a motor neuron disease which weakens the muscles and progressively hampers physical function

Huntington's disease, which is an inherited condition that cause the nerve cells in the brain to degenerate

Alzheimer's disease, which covers a wide range of disorders that impacts mental functions, particularly memory.

Mayo Clinic also noted that the nervous system can also be affected by vascular disorders such as:


Stroke, which occurs when there is bleeding on the brain or the blow flow to the brain is obstructed;

Transient ischemic attack (TIA), which are mini-type strokes that last a shorter period of time but mimic stroke symptoms; and

Subarachnoid hemorrhage, which is specifically bleeding in the space between your brain and the surrounding membrane that can be the result of a trauma or rupturing of a weak blood vessel;

Infections such as meningitis, encephalitis, polio, and epidural abscess can also affect the nervous system, the NIH noted.


Treatments vary from anti inflammatory medications and pain medications such as opiates , to implanted nerve stimulators and wearable devices, Gozani said. [Many people also turn to herbal and holistic methods to reduce pain, such as acupuncture."
