The catfish is a species of freshwater fish consumption with an elongated body and skin slippery catfish was found in brackish water or salt water. Habitat in the river with the water flow slowly, marshes, ponds, reservoirs, rice fields were flooded. Catfish are noctural, which is actively engaged in search of food at night. During the day, catfish silent and take refuge in dark places. In nature catfish spawn in the rainy season.
Let Immediately us how to cultivate catfish, First:
1. Location
There is sufficient water resources technically, available throughout the year. For the maintenance of seed discharge required is 0.5 liters / sec.
2. Water quality
Live at 25-32oC temperature, the optimum temperature of 30oC, water 6.6-8.5 pH, dissolved oxygen (DO)> 4 mg / l (ppm), levels of ammonia (NH3) <0:01 mg / l, and the brightness of a pool of up to 50 cm. Catfish also can live in calm water and deep enough, even if the water conditions ugly, muddy, dirty, and poor O2 substances
3. container cultivation
Catfish rearing ponds rectangular shape with the construction of an embankment ground or wall with a strong and capable of holding water. A minimum area of 100 m2 with water depth of 0.75-1.5 m.
4. Land Preparation Process
a. Drying
b. Fertilization (organic and inorganic)
c. Liming
d. Charging water gradually until optimal
5.Maintenance processes and Seeds
a. The size of the seeds to 5-8 cm with a stocking density of 50-100 fish / m2. The provision of artificial feed (pellets) 3-5% portion of the biomass. Frequency of feeding 2-3 times a day and Feed Conversion Ratio (FCR) is 0.9-1.2.
b. for water in the pool / tub cleaned one month with a weight of 100-150 grams per head, or the length of 25-30 cm per bird.
c. Catfish harvested after the maintenance period of 3 months with a weight of 100-150 g / head or length of 25-30 cm per bird.
After That Feeding:
a. The first day until the third, catfish seed gets food from the yolk sac (yolk sac) were taken from the hatch
b. The fourth day until the second week fed zooplankton, namely Daphnia and Artemia that have 60% protein. The food is given at a dose 70% x biomass per day, divided into 4 doses. The food stocked around the entry point of water. Approximately 2-3 days before feeding zooplankton ends, catfish seed must be introduced with food in the form of flour, 50% protein content. A little of the flour is given to the seed 10-15 minutes before administration of zooplankton. Teoung the form of food can be made from a mixture of egg yolks, shrimp and a little flour porridge nestum
b. The fourth day until the second week fed zooplankton, namely Daphnia and Artemia that have 60% protein. The food is given at a dose 70% x biomass per day, divided into 4 doses. The food stocked around the entry point of water. Approximately 2-3 days before feeding zooplankton ends, catfish seed must be introduced with food in the form of flour, 50% protein content. A little of the flour is given to the seed 10-15 minutes before administration of zooplankton. Teoung the form of food can be made from a mixture of egg yolks, shrimp and a little flour porridge nestum
c. The third week fed as much as 43% x biomass every day
d. The fourth and fifth Sunday fed as much as 32% x biomass every day
e. Fifth week fed as much as 21% x biomass every day
f. The third week fed as much as 43% x biomass every day
g. Sixth week can be tested by administering the floating pellets.
d. The fourth and fifth Sunday fed as much as 32% x biomass every day
e. Fifth week fed as much as 21% x biomass every day
f. The third week fed as much as 43% x biomass every day
g. Sixth week can be tested by administering the floating pellets.
and catfish ready for harvest and success
