airborneguy, Im going to begin my career as a biologist, I don`t want to study biology for become an aquarium keeper. It`s important to know about all the things that round us and how to save them because the world is changing (sounds like a political speech but it`s true) and anything we do as little as a sandgrain may work. This crab here in Colombia is an important food resource for all the people that live on the coasts of our seas. But, why the interest for breed them in captivity? You know that the human population is growing rapidly, and even quicker in the "forgotten zones" of our government; and the demographical increase means more food consumption and more animal sacrifice without control. The saban freshwater crab "neostrengeria macropa", endemic from Bogotá, the place where I live, is fished without controls from the state and it`s nearly going to extinction, so, my objective is to prevent the discriminated hunting and if people wants to consumpt them, make a breeding store, but avoid extracting them from the natural media, where maybe the government may protect them in speial zones of some natural park. thanks for the welcome
