Aquatic food webs and the effect on humans lives

The world's waters were once seen as a boundless source of fish for humans to eat, but over-fishing and aquaculture have depleted some species and left others famished and weak. These conditions accumulated with climate change and degrade which cause more stressful to fish populations. Different temperature causes uncertainty water masses in the ocean. This means warm water more forced to the poles. These differences affect food webs and habitats.

While, in many countries in developing aquaculture, are not supplied with sufficient sustainable management, which is in turning, the food linkages are being cut, such as mangrove areas have been changed for the aquaculture site. Changing the natural functions of mangrove also contributed in increasing carbon dioxide in the atmosphere. When the excessive carbon dioxide present, photosynthesis eliminates and the rest absorbed by ocean. In the ocean, this may lead to acidic condition that causes coral bleaching. It then causes breaking off food web and biodiversity.

In addition, the big fish seems mostly appeared on the wealth countries. For example, salmon and tuna have been over-fished. When these are hard to obtain, then small fish is targeted and it’s under pressure. Which is not supposedly used for human consumption. The potential problems are remained lying ahead, and all about how we are going to deal with these situations to sustain our lives.

Aquaculture is the option, but how sustainable management can be reached to address the issues and to derive maximum production in sustaining human life. There have been many adverse effects raised. In future, development has to be considering the adverse effects. And any single project has to be included a comprehensive assessment which is environmentally friendly. The objective is to minimise any impact that may rise and allow sustainable resources management.
