We really don't cater to wild turtles, and the pig-nosed turtle is a species that is extremely difficult to keep in captivity which should only be attempted by national aquariums. Here is an excerpt on feeding from www.austinsturtlepage.com:
"...thrive on a diverse diet of figs, apples, other fruits, eel weed (Vallisneria sp.), whitebait (Pisces) and shrimp per one source2. I recommend inclusion of a strong brand name commercial tortoise or box turtle food (Mazuri, ZooMed, etc…) with Vit. D3 content. Given that UV-B penetration of water is sub-optimal & they generally don’t bask, dietary Vit. D3 is necessary so consider a quality Vit. D3 supplement. Flavia said her's like aquatic plants (like water lettuce), and she recommended they be part of the diet. Menikos suggested Spirulina algae wafers."....
