Pond Boss Forums STOCKING A NEW POND Types of fish to choose Tilapia-this year's thread

Haven't posted for awile, here's the update on the tilapia tank: We had several problems. The tank was set up and filled with water to give the chlorine time to dissipate. After setting up the tank (old hopper tank ring)I measured it and calculated that it is only about 700 gallons. We returned the next morning to find the tank half empty. A new liner was donated and the heater was resized and ordered. Only $140 for 2500watt heater, controller, and cables. There were 205v plugs in the roof so we just added a GFCI an plugged it in. When hooking up the heater we accidentally burned a hole in the new liner but we were able to patch it. The water pump they had turned out to be an air pump, 25CFM. I decided to use this for moving water through the filter. The filter was built out of a large trash can. Three 3" holes were drilled in the bottom. 1/4" mesh was used to cover the bottom except for one 3" hole. A 4'with many 1/2" holes drilled in it and a 2-1/2' piece of salvaged plastic pipe were joined at an elbow. The 2 1/2' piece was passed through the bottom of the trash can. The trash can was then set on a couple of concrete blocks, filled with media and topped with filter fabric. 4 airstones connected to the air pump were placed about 2/3 down inside the verical pipe coming through the bottom of the trash can. Works similar to an undergravel filter in an aquarium but rather than pulling the water down through the gravel in the bottom of the tank it lifts it and spills it over the filter fabric before trickling through the bacteria housing pea gravel media. The advantage is that the piece of fabric catches most of the solid waste and it can be easily removed and cleaned as needed. 300 2" to 3" nile tilapia were added on Friday. My newest problem is that these tilapia are 98% female according to the supplier. If this is true, how many males would be needed to promote successful spawning in my pond this summer for bass growth?
