The number of the eggs spawned by seahorses each time is limited. The average numberis from many hundred to more than one thousand. If we want to make the massproduction of seahorses, we have to culture many seeds in order to supply enough fries.Besides the production of the seeds is numbered, whether mating is successful or not isanother key factor of limiting the production of the fries. Therefore, it is necessary tobuild a good matching model under the circumstances of aquaculture. We will usedifferent environmental factors and mating rate to promote the proportion ofseahorses(Hippocampus kuda) matching and the proportion of successful matching.We can adopt the good skills of the seed production at the same time, and thus we canbuild a good production technique of seahorses.
