The average size of fish caught for some species has dropped until there is now a significant need to impose minimum size limits, or capture moratoria, to allow these and other species to reach reproductive age and size before being removed from the population.

Similarly, the high infrastructure and labour requirement along with the variable cost for live feed production illustrates the need to develop suitable modified culture technology. Nutritional status of live food organisms can improve through various techniques of enrichment and bioencapsulation.

It is advised to keep male and female fish in separate tanks. Feeding of aquarium fishes with natural and artificial foods: Difficulties in getting pure strain, lack of infrastructure facility like controlled environmental laboratory for culture maintenance etc.

This is especially common when groundwater that has high alkalinity and hardness, as well as elevated carbon dioxide concentration, is brought into contact with the atmosphere.
