įor example, in the aquarium, I would avoid all citrus fruits, tomatoes, avocado, etc. Terrestrial, semi-terrestrial, and aquatic (freshwater and marine) crabs should be fed differently. That is why it is very important to understand that they need to have a varied diet of: By doing so, crabs will get all necessary microelements, vitamins, and minerals that are needed for their body to function correctly. So, if we want to give them the best life possible, we need to provide them with a well-balanced diet. This approach will only lead to diseases and problems with their exoskeleton. What Do Crabs Eat In The Aquarium?Ī simple fact most crabs are not fussy eaters by nature does not mean that we can give them whatever we like or that we should not care about their diet. They feed on a variety of plant materials as well as on decaying organic matter, like: leaves, plants, flowers, belowground rhizomes, fruits, vegetables, barks, seeds, grains, etc. Some terrestrial crabs of Sesama family are common herbivores. Basically, it means that they will eat anything left unattended on the ground, as they are scavengers.Īt the same time, certain species and even families show tendencies towards a more specialized diet.įor example, Portunid crabs are reported as being mainly carnivorous, feeding on many organisms, particularly on slow-moving invertebrates such as molluscs, snails, slugs, worms and crustaceans (including other crabs up to their own size). They will eat plant and animal matter that they come across. In this article, I will highlight the various food sources available to crabs for consumption, and how often they should be fed in captivity. In addition, their feeding preference may change depending on the age and the molting cycle. Each species has its own feeding requirements. I am saying “generally” because they’re more than 4500 different species of crabs in the world and about 50 species that are heavily traded in the aquarium hobby. It can be detritus, animals, and plants, either living or decomposing. They will eat just about anything they can get their claws on. Generally, crabs are omnivorous and opportunistic feeders.
FEED AND GROW FISH CRAB HOW TO
So, if you are looking to keep them as pets, it is important to do research on how to take care of them and how to feed them. In addition, pollution of the water environment and fluctuations in the water parameters for crabs due to improper pond preparation, pollution and climate change have added stress to the crabs.Owning a pet land crab or aquatic crab can be a very worthwhile and unique experience. The price of trash fish has increased significantly due to its unavailability in several areas.

On the other hand, pelleted feeds serve as an alternative feed that addresses the problem of the declining supply of trash fish, corn, mussel and snails. It was noted that there are still farmers in some areas that use low value fish for feeding crabs resulting in the deterioration of the pond bottom and water environment. On the other hand, farmers in Quezon, Bataan, Masbate, Negros and Capiz are growing crabs to marketable size for domestic and export markets. Farmers in Bicol region, specifically Sorsogon which is one of the sources of wild crablets in the country, are presently using pelleted feeds for nursing different crab sizes. Nursery and grow-out operations in these areas vary in terms of their feeding management and techniques for a better yield. Mud crab (Scylla serrata) farming has been one of the means of livelihood of many Filipino farmers in coastal areas, specifically in Southern Luzon and Visayas.
