It is estimated that 99 percent of all production problems in crawfish ponds are related to poor water quality. Dissolved oxygen (D.O.) is the most serious problem, but pH, total hardness, total alkalinity, ammonia, nitrite, hydrogen sulfide, and iron can also affect crawfish production.
DNA Land is a place where you can learn more about your genome while enabling scientists to make new genetic discoveries for the benefit of humanity. Our goal is to help members to interpret their data and to enable their contribution to research.
The acre is a unit of land commonly employed within North America and the Caribbean. It is equal to 4,047 square metres or 43,560 square feet. This measurement is roughly equivalent to 40 per cent of a hectare. Interestingly enough, the acre can trace its roots back to mediaeval times.
