The environment is everything that surrounds us and therefore it is the place where we exist and live. However, because humans are terrestrial organisms, when the word "environment" is mentioned, the marine environment does not usually come to mind. My biology site visit, at the secondary level, took place at MARC and it was there that my eyes were opened to the continuous and laborious work that takes place behind the scenes, shielded from any public knowledge. So I decided to embark on this project in order to delve deeper into what is happening in these centers and how these centers aim to combat unsustainable fishing by trying to produce fish on a commercial scale. Fish farming is not an easy task and hence this project aims to analyze how fish health is controlled. This is done for example by carrying out physical (through the use of instruments) and chemical tests to check temperature levels, oxygen concentrations, etc. to ensure that an ideal and consistent environment for fish is maintained. Growth is monitored by sample weight while the health of adult fish is monitored by the quality of their eggs. To prevent natural selection from occurring, that is, larger fish being favored over smaller ones, a process known as ranking takes place in which fish are separated into different tanks based on of their respective weight. I did not have the opportunity to observe this process since it took place during school hours. MARC is also known for its turtle rehabilitation center where injured turtles are brought to the center so that they can regain their health. Thus, it is very clear that every activity that takes place within the center is in one way or another linked to science...... middle of paper ....... The injured turtles are taken to MARC, where they are examined and treatment by a veterinary doctor is administered. At MARC, the progress of the turtles is monitored and before they are released into the wild, they are measured and tagged. Sea turtles still face serious threats from the loss of nesting habitats where coastal development, nest predation and human disturbance disorientate hatchlings. Bycatch in fisheries and pollution have also played a significant role in the decline of turtle populations. Overall, this project opened my eyes to the many projects Malta is involved in and how the foundations of such aquacultures are built through basic biological knowledge. This shows that sustainability is not an impossible dream but can be easily achieved through proper thinking and collaborative working..
