Genesis 1:28
“And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.”
Researchers have learned that some fish have an absolutely amazing ability – a specialty that is of considerable help to fish and to man as well. This remarkable gift is the capacity to change sex after they are hatched!
Scientists have learned that silverside eggs placed in relatively warm water will eventually produce mainly male fish, no matter how many females originally hatch. At the same time, eggs allowed to hatch in relatively cold water will produce mainly females.
This is an advantage because eggs hatched in warm summer waters have the winter ahead of them, and young, strong males are more likely to survive the winter than young females. On the other hand, eggs hatching in the spring usually hatch in cold water, producing females that have plenty of time to grow before facing winter. Researchers point out that these findings could be of tremendous help to fish hatcheries that wish to manage their populations and production.
Our Creator has wisely provided for the preservation of His creatures. He has designed some of these gifts in such a way that human beings can use them to put the earth and its plants and animals into service for their as well as our good. The witness to our Creator could not be clearer.
Prayer:
Heavenly Father, I thank You that You provide for the needs of all Your creatures. Help me to be a good steward of Your creation. In Jesus’ Name. Amen.
