Giant fresh water prawns Feeds

Giant fresh water prawns Giant fresh-water prawns are commercially important because of their size, as well as their eating qualities. Similar to tiger shrimps and other arthropods, giant fresh-water have buccal appendages in the mouth parts for chemoreception and prey capture. Giant fresh-water prawns also find their foods mainly by chemosensory mechanisms using their antennae and antennules rather than their vision. They prefer to eat their foods at the bottom of the pond, at night, by using the first two pairs of chelate pereiopods. Giant fresh-water prawns fed primarily of phytoplankton, mainly diatom, however, they orient towards a carnivorous diet. Young prawns change their feeding behavior from waiting for free-swimming plankton to eating at the bottom of the pond when they are about 2-3 cm. Adult prawns are described as omnivorous and they consume both living and dead organisms. Generally, giant fresh-water prawns are fed fresh foods (minced or chopped fishes), mixture of fresh foods and commercial feeds or only commercial feeds. Commercial feeds are preferred because they are very easy handling and contain complete and balanced nutrient compositions. Moreover, feeding commercial feeds helps maintain acceptable water quality. However, Fresh foods or mixtures of fresh foods and commercial feeds can be fed sometimes as supplemental feeds. The daily amount of feed offered if affected by the size of prawns, feeding schedule, stocking density, availability of natural foods, dietary level, water quality, and prawn health. Practically, feeding frequency should be at least twice a day, however, for maximum feed efficiency, feeding 4 times a day (06.00am, 11.00am, 04.00pm, and 09.00pm) is recommended. Feeds should be distributed uniformly over the whole pond on the designated schedule. If the temperature drops below 2 C, feeding schedule in the morning should be skipped. Feed remaining on the feeding trays should be determined for daily feed allowance adjusting.
