About :
Today a film about how to breed grindal. Grindal was first isolated from its larger cousin in the 1950s by Mrs. Morten Grindal (hence the name), who had previously become famous for developing methods for breeding the enchytraeid. The popularity of grindal is due to several factors. Firstly, it grows to a maximum of 10 mm (usually 5-8 mm) in length and reaches 0.5 mm in diameter, making it an ideal food for fry (when Artemia, micro nematodes, banana worms are already too small) and small species of fish - carnivorous and omnivorous. Secondly, its nutritional value is very good: protein - 70%, fat - 14.5%, minerals - 5.5%, carbohydrates - 10%. Apart from that, its breeding is very simple. We feed the fry with girndal most often from the 10th to the 15th day, depending on the species (basically when the brine shrimp becomes too small), usually when it reaches a length of about 10 mm. When feeding adult fish, this food should not be given more often than once or twice a week. There are two methods of breeding. One involves breeding on soil/coconut fiber, and the other - on a synthetic substrate - sponge. Grindal tolerates a wide range of temperatures: 20-30 degrees Celsius, so room temperature is sufficient. The optimal temperature is 22-25 degrees Celsius. As food for grindal we use: dry dog/cat food, fish food and dry yeast (I grind all the food into a fine powder, add dry yeast and use it in this form).
