Print Humans have always eaten meat , but does meat now threaten our survival? Many governments and institutions believe so. Reports from the United Nations , Oxford University , and others claim our appetite for flesh food could soon ruin the planet. Anticipating the near future with the meat-eating habits of today, experts fear food shortages and environmental devastation. In light of this threat, there is a big push among policymakers to get us to back off from burgers, bacon, and barbeque. Rodgers, who lives on an organic farm west of Boston, is also working on a documentary exploring the ways in which raising meat may actually be good for the environment. But Rodgers points to historically large herds that have lived in harmony with the environment. Consider the 30 million to 60 million bison that once roamed North America years ago. Ruminants—a fancy word for large grazing animals that include cattle, bison, and wildebeest—are born to roam.Necessary phrase: The Pros And Cons Of Factory Farm Animals

Through this work, the researchers noticed tags do not always work as intended, and sometimes affected the fish negatively. But if tags change the behaviour or welfare of fish, the information they give may not represent the wider untagged population," the reseachers note.
As a result, they decided to dig deeper and, after receiving funding from the Research Council of Norwaythey systematically reviewed studies that used tags to monitor farmed fish behaviour.
Several concerning discoveries emerged. Firstly, tagged fish mortality was 10 times higher in studies conducted in sea cages compared to tanks. In the cages, one in four tagged fish died within the period they were studied, and in general, the longer the study, the higher the mortality rate.

And in many studies, important information, like the mortality rates of tagged and untagged fish, was not reported, which makes it difficult to work out the effects of tags. Why tags affect fish welfare in sea cages Experiments conducted in small tanks are typically done under controlled culture conditions, where researchers can largely prevent poor water quality and other adverse events, like algal blooms or pollution. In comparison, experiments conducted in large sea cages, filled with thousands of individuals expose fish to stressful condidtions - including fluctuating temperatures, salinity, dissolved oxygen, current, pollutants and pathogens - which can affect their behaviour, welfare and survival. These findings have several implications: Results obtained in tanks are likely not transferrable to sea cage environments. High mortality rates in sea cage experiments call into question how representative tagged fish are of the whole fish population.

Tagging in marine sites poses significant animal welfare issues. In sea cages, fish are also exposed to other stressful conditions like crowding or environmental extremes — and unlike the wild, caged fish cannot swim away from unpleasant conditions," say the researchers. The Health and Welfare of Atlantic Salmon course It is vital that fish farm operatives who are responsible for farmed fish are trained in their health and welfare. This will Conx to ensure that fish are free from disease and suffering whilst at the same time promote good productivity and comply with legislation.

Find out more "We think the additional stressors present in the sea-cage environment make it harder for fish to recover from the initial stress of tagging and that this leads to a lower chance of survival," they add. When animals must be used, Reduction minimises the number of animals being used. Refinement ensures research methods are advanced so that animals experience the least amount of suffering possible. However, where researchers need to use tags they recommend reducing the number of fish Aniamls to a minimum that will still provide large enough sample sizes to get relevant results.
They also have recommendations for future tagging research to refine the tagging procedure by encouraging researchers to: Carefully record the tag attachment procedure, including important information like tag dimensions, water temperature and type of anaesthetic used. CCons information about any physical effects from tagging, such as if fish display inflammation near the tag attachment site.

While tagging has a lot of promise, it needs significant improvement to safeguard the welfare of tagged fish in aquaculture. Read the original article here.]
