Giving Fish Feed carp
Carp is a fish that has a somewhat slower growth but the price is relatively increased at any time. Carp (Osphronemus goramy) is a type of freshwater fish are popular and well liked as a food fish in Southeast Asia and South Asia. Carp including fish farming that need more attention in cultivation compared to other food fish.
Carp breeding success starts from the feed delivery techniques. There are several things that must be considered by the farmers for cultivation of carp can be successful and produce.
Regular feeding with high quality and quantity can improve the growth of the fish more quickly. Parent-parent and guaranteed healthy carp diet twice a year can dipijahkan row for 5 years (www.ristek.go.id). Carp fish known as the slow movement that is often unable to compete with other fish species in the fight over animal foods. So it is not surprising that growth is not as fast as other omnivorous fish.
To stimulate the growth of carp should be given animal and vegetable food in the ideal composition. Carp can not be 100% of the feed mill because the meat will become mushy. To meet the feed plant, can provide various types of vegetation such as sente leaves, water spinach, cassava leaves, water plants or the leaves of land plants are soft and young. If the coupled enzyme complexes, the composition of animal and vegetable feeding well is 2% / kg. Based on the experience of some farmers, giving sente leaves (Alocasia machoriza), a type of taro showed the best growth. Vegetable feeding begins when the seed about the size of a match or approximately 3.5 months old (Agus, 2001).
The feed is given in the form of pellets with protein content adjusted to the size of the fish if: a). 3-5 cm size fish protein content of 38%, b). 5-15 cm size fish protein levels 32% and c). Size of fish> 15 cm in the protein levels of 28% (National Standardization Agency, 2009).
Daily ration of artificial feed made periodically with a dose of 1-3% of the weight of biomass per day with a frequency of 1-2 times per day ie morning and afternoon. While forage feed is given at a dose of 1-2% of the weight of biomass per day with a frequency of once per day.
With the benchmark dose, then the weight of feed per day can change with the addition of weight of fish in the pond. Addition of weight is often referred to as growth. The amount of growth can be detected through sampling technical (pick up some fish and weigh its weight). Total weight of fish in the pond is the multiplication of the average weight of fish sampled by the number of fish that are kept. Adjustment of the amount of feed adjusted to the total weight of fish sampling is conducted once in two weeks.
