How do fish grow

This has important implications for fisheries and aquaculture. Despite having many applications, the GOLT has been the subject of criticisms. In the new paper, Pauly responds to these challenges point by point. Thus, it was important to clear them out so that the GOLT can start to be seriously studied, and its real problems addressed.

Fish come in a variety of different shapes and sizes, and studies on wild populations have provided the aquatic trade with huge amounts of information on what to look for in a healthy, fully grown fish.

At Maidenhead Aquatics we use these facts to advise our customers on the most suitable aquaria for their fish, taking into account the adult size they are likely to achieve. While it may seem that some fish do grow to the size of the tank, it is more likely that due to unfavourable conditions, the animal unfortunately doesn't get the opportunity to fulfil its full potential.

Put simply, fish that cannot grow to their full size are stunted or deformed. The animal has not made a conscious effort to stop growing and we need to consider the welfare of any creature in this state. Changing water regularly will keep nitrate levels down. Pheromones are like hormones, but they actually work outside the body. Under certain conditions, many animals will release pheromones from their body, which then provoke reactions from other animals of their species.

Some pheromones will attract others of the same species, while some will drive them away. They are especially common when it comes to mating. Certain species of fish, including goldfish and some cichlids, will emit pheromones that can limit the growth of other fish. The idea is to give themselves a competitive advantage over the local crowd by being the biggest and strongest. As with nitrates, regular water changes will prevent secreted pheromones from accumulating in the tank.

If you want to have some idea how big your fish might get, you can start by asking at the aquarium store before you buy. There are also many great resources available to help you on the Internet.

This might seem like the humane thing to do, but it may be lethal to the fish or damaging to the indigenous species.
