Grindal is a special kind of fiber created from a special kind of worms same like the silk fiber is made by worms. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. Silk is produced by several insects; but, generally, only the silk of moth caterpillars has been used for textile manufacturing. Process of extracting silk: Extracting raw silk starts by cultivating the silkworms on mulberry leaves. Once the worms start pupating in their cocoons, these are dissolved in boiling water in order for individual long fibres to be extracted and fed into the spinning reel .

Grindal Worms Culture and Complete Guide

Grindal worms (Enchytraeus buchholzi) are one of the best live food sources for feeding aquarium fish. It is too easy to culture these worms in large quantities. Also, grindal worms are a very nutritional live food source for aquarium fish. They have a nutritional value of about 70% protein and 14% fat. That makes them a valuable addition to an aquarium fish’s diet. Additionally, due to its rapid and continuous multiplication ability, it is widely cultured and used for feeding aquarium fish.

What are grindal worms?

Grindal worms (Enchytraeus buchholzi) are first described by František Vejdovsky in 1879. They are small and white non-parasitic enchytraeid oligochaete worms. The scientific classification probably covers a group of small and morphologically indistinguishable worm species that live in soils across the globe. The name grindal worm comes out later when it was beginning to use in the aquarium hobby. Mrs. Morten Grindal of Sweden, who was working on improving the culturing techniques for white worms was the first aquarist to isolate this smaller species. After her studies, these worms are called grindal worms in the aquarium hobby.
