In males, tubercles occur from mid-May to early August with peak development going from June to July, at the same time as other indicators of reproductive condition.

Can fathead minnow Pimephales promelas induce vitellogenin production?

The fish fathead minnow Pimephales promelas was exposed for a year to a concentration of 3.2ng/L EE2 and induced vitellogenin production. Yunwen Tao, … Qinhong Cai, in Advances in Marine Biology, 2018

When is the best time to stock minnows in a pond?

There is some debate about the best time to stock minnows. Some suggest stocking them into a pond before adding other fish. However, having minnows in the pond prior to stocking fingerling bluegill and largemouth bass will not benefit the pond.

Fractional spawning can result in 16 to 26 spawning events per female and an annual fecundity of 6,800 to 10,600 eggs per female.

Is the NOAEC for EE2 for fathead minnow egg production too high?

The results of this study indicate that the previously reported no observed adverse effect concentration (NOAEC) for EE2 on fathead minnow egg production (1.0 ng/L) may be too high.

How many Fatheads can you put on an acre?

How much carp do I need to stock my pond?

2000 per surface acre. 10 lbs. per surface acre minimum. When stocking Grass Carp we recommend 10 per acre of vegetation. Vegetation will always grow more abundantly in clear water ponds. For this reason we strongly recommend that in all spring fed ponds, the Grass Carp be stocked at a rate of 15 per acre of vegetation.

What are the characteristics of native Missouri minnows?

Native Missouri minnows share the following combination of characters. You can use these to separate them from our other small fishes: The fins lack spines. There are 8 principal rays in the dorsal fin (9 in the pugnose minnow), and 16 or fewer principal rays in the anal fin. The body is covered with smooth-edged (cycloid) scales.

What is a mimic shiner fish?

How many gallons of water does a pond hold?

Let’s test these rules using an average size pond that’s 10’ x 15’ with an average depth of 18” (1.5 feet) and is 24″ at the deepest point. We can also assume it’s a liner pond with rock and gravel. Calculating the water volume: 10′ (length) x 15′ (width) x 1.5′ (av. depth) x 7.5 (gal/cu ft) = 1,687.5 gallons.
