X, £», 5 Daij: Culture of the Bangos, or Milk fish 311 



December. By using care — that is, drying the pond and not 

 stocking at once — the owner thinks as good algae could be obtained 

 in the dry as in the rainy season. 



Five thousand fry are needed each time to stock the pond, 

 at 50 centavos per 1,000. Only two fifths of these mature, be- 

 cause of the presence of other fish, such as pompano, bia (Oxye- 

 leotris ?), and dalag (Ophiocephalus striatus Bloch.) The fish 

 when sold average 23 centimeters in length and sell at 3 for 20 

 centavos. Because of the small size of the fish, the owner says 

 he gets but 150 pesos per year from their sale. The pond cost 

 2,000 pesos to build, and the owner is willing to sell for 1,000 

 pesos. 



IBA, POND NO. 3 



Mr. Eugenio Frierro is the owner of pond No. 3, which is in 

 process of construction. It will have an area of about 4 hectares, 

 and the cost of construction, including excavation, building of 

 dikes, etc., will be about 500 pesos. The value of the land is 150 

 pesos. 



This pond lies near pond No. 2, belonging to Pio Acayan, and 

 presents about the same conditions. Considerable excavation 

 is necessary, and there are many trees to remove. Soil conditions 

 are about the same as in the other ponds at Iba. There is a 

 mixture of sand and mud, with a decided tendency for the mud to 

 accumulate in the bottom of the pond. Algae in plenty were 

 found growing, and with proper care given to the regulation of 

 the number of fish in the pond, the same results as in the other 

 ponds in Iba should be obtained. 



IBA, POND NO. 4 



Pond No. 4 is the second pond of Mr. Pio Acayan. It has an 

 area of about 4 hectares, and will cost approximately 500 pesos 

 to construct. The bottom has a little more mud than that of 

 Jose Venzon, although the conditions are almost identical. 



IBA, POND NO. 5 



Mr. Pablo Mercado is the owner of pond No. 5, which is located 

 to the north of the town of Iba. This pond is in process of 

 construction, but promises to be satisfactory and profitable. 

 Conditions are much the same as in Iba pond No. 2, the first of 

 Pio Acayan. 



IBA, POND NO. 6 



Pond No. 6, owned by Mrs. Tranquilina Fierro, contains 50 

 ares, but can be made to include 100 ares. Thus far construction
