Can Ocean Sunfish Be Eaten? Nutritional Value, Diet, and Whether Strong Sunlight Can Kill Them

Ocean sunfish, also known as sunfish, mambo fish, or head fish, is a collective term for 3 species of oceanic fish in the family Molidae, class Osteichthyes. They are distributed and inhabit tropical and subtropical oceans, and are also found in temperate or cold oceans. So, can ocean sunfish be eaten? What nutritional value do they have? What food do they eat to grow? Will they be killed by strong sunlight?

1. Can ocean sunfish be eaten? What nutritional value do they have?

Ocean sunfish can be eaten. They have relatively high economic value; besides being used for scientific research and ornamental purposes, they are also a valuable food fish. They have many bones and little flesh, and after skinning, the flesh is about 1/10 of the body weight, but the meat is delicious, white in color, and high in nutritional value, with a protein content higher than the famous pomfret and ribbonfish. The intestines of the ocean sunfish are also very expensive; Taiwan, China has a famous dish called “Miaolong Soup” that uses them as the main ingredient, and eating it is both crisp and fragrant, greatly whetting the appetite. In addition, the fish skin also has great uses; it is a raw material for making gelatin or fish oil and can be used as a lubricant for precision instruments and machinery. The fish liver can be used to make cod liver oil and edible hydrogenated oil, etc.

2. What food do they eat to grow?

Ocean sunfish are carnivorous fish, mainly feeding on jellyfish and zooplankton, and they also eat crustaceans, sea jellyfish, and algae.

3. Will ocean sunfish be killed by strong sunlight?

Ocean sunfish will not be killed by sunlight that is too strong. In English, the ocean sunfish is called Ocean Sunfish; the reason they are called “sunfish” is that people often see them lying on their sides on the sea surface enjoying a “sunbath.” As for the claim that they die from “excessive stress” and “too great a shock,” the scientific community has no reports on this.

Moreover, the ocean sunfish is a relatively long-lived fish. According to growth curves simulated by captive breeding research, it is estimated that they need at least 20 years to grow to 3 m in length. Therefore, leaving aside whether ocean sunfish can feel “emotional stress” and “too great a shock,” for such a long-lived fish, a certain “psychological resilience” should still be expected.
