At the same time, they have have some specialized requirements for their food. Many household foods, particularly seafood make great pufferfish fare. Hard, crunch food like unshelled shrimp help maintain a puffer's teeth.
On the other hand, crabs and shrimp contain a chemical called thiaminase, which interferes with the absorption of vitamin B1. You can get around this by soaking thawed crab and shrimp in B1 supplements, available at high-end pet shops and online, or only feeding these sparingly. A puffer will eagerly eat clams, cockles and mussels. Mussels probably make the best food for puffers, since mussels have thinner shells that puffers can crunch with their beaks.
You can feed these items whole to larger puffers, or finely dice them for smaller species. Like crustaceans, mussels contain thaminase, but you can soak them in supplements to make up for it. A varied diet can overcome this issue as well. Remove the skin there are no scales. Cut around the mouth and, from there, pull the skin off.
Wash off the jelly now coating the fish with salt. You can eat the outer skin when cleaned and blanched but there is great skill involved in removing the spines: hold the skin in one hand and slice them all off with a knife in one movement.
Now gut your fish. Be very precise with your knife because the ovaries and liver contain most of the poison. If you burst them while removing them, they will release toxins into the flesh. Fillet as normal for sashimi, cutting up against the bone.
Most are found in tropical and subtropical ocean waters, but some species live in brackish and even fresh water. They have long, tapered bodies with bulbous heads. Some wear wild markings and colors to advertise their toxicity, while others have more muted or cryptic coloring to blend in with their environment. They range in size from the 1-inch-long dwarf or pygmy puffer to the freshwater giant puffer, which can grow to more than 2 feet in length.
They are scaleless fish and usually have rough to spiky skin. All have four teeth that are fused together into a beak-like form. The diet of the pufferfish includes mostly invertebrates and algae. Large specimens will even crack open and eat clams, mussels, and shellfish with their hard beaks.
Poisonous puffers are believed to synthesize their deadly toxin from the bacteria in the animals they eat. Some species of pufferfish are considered vulnerable due to pollution, habitat loss, and overfishing, but most populations are considered stable. All rights reserved. Common Name: Pufferfish.
