Depending upon the species of fish being farmed and the expertise and equipment being used by the fish farmers, some species are spawned and fertilised naturally and others have their ova and sperm stripped from the breeders by hand and these are then mixed together so that fertilisation can take place in small containers.
Most fish use external fertilization. But not all, guppies and other livebearers use internal fertilization. Of the external fertilizers, some are broadcast spawners, whereas others are not.

Sharks have internal fertilization through the use of a clasper.
Fish use outer fertilization because they are not Mammals , which use inner fertilization . Mammals generally bear live young , with few exeptions . Fish and other cold blooded animals lay eggs which are fertilized outside the body , again with few exeptions .
External takes place outside the female, as with fish eggs on which the male fish places his sperm. Internal fertilization, in plants and animals, takes place within the organism's structures, where the gametes are joined. In humans, in vitro fertilization (i.e. test tube babies) is a form of external fertilization in that it bypasses the normal occurrence in the fallopian tubes, and then directly implants the fertilized egg(s) in the uterus.

Yes, you can use bottled water for your fish tank, but it is important to ensure that the water is suitable for your specific type of fish and that it does not contain any harmful chemicals or additives. It is recommended to test the water parameters and consult with a professional before using bottled water in your fish tank.
