Natural production
Stimulating natural production in a pond through fertilization provides cultured shrimp with a portion of their food (FAO, 1984b; Focken et al., 1998). Natural food organisms play a major role in the overall nutritional budget of pond-reared shrimp, even at high stocking densities (Tacon, 2002). Penaeus indicus is a predator of benthic invertebrates (Angsupanich, Chiayvareesajja and Chandumpai, 1999).
Complete Feeds
A complete feed is a formulated pellet that provides all required nutrients in the proper proportions necessary for rapid weight gain, high feed efficiency and necessary shrimp health and quality (Figure 16). Feed cost is about half of variable production costs in shrimp culture, so a shrimp producer should carefully consider feed selection and use (Lim and Akiyama, 1995). The recommended nutrient levels for commercial shrimp feeds are in given Tables 2a and 12. |
