There is plenty of fish in the sea. Not just figuratively but literally speaking.
Several kinds of fish from the healthy ones to the contaminated one swim on the vast ocean. Rockfish included. But in what category does this fish belong? Or what is it in the first place?
Rockfish is the generic term of fish caught in the East and West Coast. But the issue does not simply end there. If you are aware of what striped bass is, perhaps you know that it can be called “rockfish” when it is sold in the same state where it is caught. Nevertheless, cowcod, chili pepper, treefish, Pacific ocean perch, and grouper are also called rockfish. The similarities with the mentioned fish are they all hiding under or around rocks. Thus, to put it simply, rockfish are the fish that hides under rocks or around it.
It might not be more confusing as the definition seems broad. However, the underlying issue is the benefit that a person can get from eating rockfish. It is safe at all? What good can it brings the body, or if there are risks included, what is it?
The Benefits of Rockfish
Fish, in general, is associated with many health benefits because of its nutritional contents. It can decrease the risk of conditions such as stroke, depression, and Alzheimer’s disease. In fact, eating fish at least two times a week is highly recommended by the American Heart Association. However, many fall short of this advice. Fortunately, the Harvard School of Public Health found the best way to achieve this goal. They said that the goal can be achieved by consuming rockfish, which aside from achieving the said goal provide additional vitamins, minerals, and essential fats that we need.
To elaborate further the potential benefits of rockfish, you may read the below list.
Rockfish is Rich in Vitamin D
Vitamin D is an essential nutrient that the body needs. It manages your weight and assists with the function of your nervous system. It is also responsible for muscle and bone health, but more interestingly, it helps fighting cancer cells.
Vitamin D’s number one source is the sun. Thus, it is basically free. However, if you are living in the area where sunlight may not reach you in a regular basis, you’re in the risk of not getting enough vitamin D. Additionally, there are individuals that are sensitive with the sunlight. These conditions require an alternative method to get enough vitamin D.
Good thing that rockfish contains vitamin D. Some other rockfish have up to 46% of daily recommended vitamin D. Thus, making it one of the many good sources of the vitamin, including egg yolks and fish oils.
It Establishes Cell
Aside from vitamin D, rockfish contains protein which is essential in making new cells. That is why protein is called the building blocks of life. It is composed of amino acids which are responsible for repairing the broken cells in our body.
Proteins are vital to the developmental stages of pregnant and non-pregnant women, teenagers, and children aside from repairing athletes stressed cells.
It Has the Ability to Boost Brain Power
Selenium is an important nutrient that is mostly found among ocean fish. Rockfish is an ocean fish which makes it a fish rich in selenium. Selenium is one of the nutrients that can fuel up the brain to make it function well.
But aside from that, selenium has an interesting antioxidant property which able it to fight cancer. Moreover, it assists with the function of the thyroid and supports the immune function as well as the heart. Lacking supply of selenium leads in many health conditions such as obesity, diabetes, pancreatitis, rheumatoid arthritis, liver disease, asthma, Alzheimer’s disease, brain tumors, Down syndrome, and autism.
The Risk of Eating Rockfish
Though rockfish has many health benefits, there are still many risks associated with it. Such as:
Some kinds of rockfish contain mercury, which health professionals point in many health issues including insomnia, thyroid issues, neurological disorder, and kidney problems. So far, the only rockfish that contains a high dosage of mercury is grouper. So, avoid eating grouper fish.
Polychlorinated Biphenyls (PCBs)
PCBs are mostly found in fish fats, internal organs, and skin. It is believed to lead in several health conditions including cancer. The worst news about PCBs are it is a manmade industrial chemical; that is why you can notice that it build up in the skin of a fish or in the internal parts which can be affected once the fish ate. Because of this issue, the Office of Environmental Health Hazard Assessment (OEHHA) advise avoiding eating the mentioned part of the fish. They recommend eating skinless fish.

Buying the Best Rockfish
Getting the freshest rockfish may be your goal when looking for the best one. To have it, you need to get the one that comes off a boat. However, if you are not living in a fishing area, your best catch is the fresh frozen at the markets. Here are some tips to help you pick the right fish.
- The first tip is to use your keen nose. Avoid fish that smell sour or ammonia-like or those that we can categorize as something “fishy”. Look for something that has a mild and fresh smell.
- Look for a fish with firm filets, shiny flesh, and bright-red gills. The gills should not have slime as well.
- Buy fish that are refrigerated or placed on fresh iced. Make sure the case has a protective cover.
- Look for fish which eyes are clear and slightly bulge. Additionally, the flesh should bounce back once it is pressed.
- When getting a fish inside a freezer, took the one that is in the bottom, and make sure that the package is sealed.
