Edibility of Killifish
One of the most important questions that arise while discussing aquatic organisms is whether they can be consumed by human beings or not. This question has gained prominence from the ever-increasing popularity of seafood among the masses. In the case of killifish, this question can be simply answered by saying, yes killifish is edible and human beings can safely consume it. Consumption of killifish by human beings is not dangerous, as it is a completely non-poisonous fish. However, they are not commonly consumed as seafood and are not generally considered as the type of species that are consumed by human beings. Most often, killifish are preyed upon by large fish-eating birds. These small-sized carnivore fish are often used as live bait for capturing other larger fishes. Apart from this, killifish are most primarily used as pets as their vibrant body colours help them to obtain a beautiful and friendly look like pets which can be kept in an aquarium. So, It can be said that killifish as an edible form of seafood is yet to be explored.
To recapitulate, it can be said that killifish can be consumed by human beings, owing to its non-poisonous nature. However, the edibility of killifish is certainly a topic that has not been explored properly on a large scale. This is resultant from the fact that killifish is often viewed as a pet fish, which can be easily kept in an aquarium at home. So, regarding the edibility of killifish, seafood lovers should have a try at other popular cuisines, which are tasty and fulfilling, as killifish has not assumed the role of popular or mostly consumed seafood and most probably killifish will remain as a pet fish and may not become part of our food.
