Sodium silicate clearing agent, though, sodium silicate is sometimes confused with isinglass which is prepared from collagen extracted from the dried swim bladders of sturgeon and other fishes. Eggs preserved in a bucket of waterglass gel, and their shells are sometimes also used (baked and crushed) to clear wine. Sodium silicate gel is also used as a substrate for algal growth in aquaculture hatcheries. Sodium silicate Sodium silicate is a generic name for chemical compounds with the formula or ·, such as sodium metasilicate , sodium orthosilicate , and sodium pyrosilicate . The anions are often polymeric. These compounds are generally colorless
Swim bladder tissues. This increases the ability of sound detection. The swim bladder can radiate the pressure of sound which help increase its sensitivity and expand its hearing. In some deep sea fishes like the "Antimora", the swim bladder maybe also connected to the macula of saccule in order for the inner ear to receive a sensation from the sound pressure. In red-bellied piranha, the swimbladder may play an important role in sound production as a resonator. The sounds created by piranhas are generated through rapid contractions of the sonic muscles and is associated with the swimbladder. Swim bladders are evolutionarily closely
