In sardine fishing, the net is typically laid around the shoal and tightened like a bag. The net is then retrieved slowly to the side of the vessel and the fish are brought aboard. In the case of the Marazion deaths, the vessels involved will be relatively small and have limited storage space so keeping everything balanced is crucial. If by sheer bad luck the net encircled a shoal of fish that was larger than the skipper realised, the boat is immediately put in a dangerous situation. A large catch on one side of the vessel will create an imbalance that will make it much more prone to capsizing when in rough seas. A fisherman died off the coast of nearby Devon in 2012 when his heavily-laden trawler capsized in similar circumstances.
Therefore if the catch is physically too large to retrieve, the vessel would have no choice other than to release the bottom of the net so that the catch falls away.
So surely the fish will swim off? Sadly not in this case. Many midwater species like sardines and mackerel are quite delicate and vulnerable to damage due to the high number of fish caught in the net. In this instance the sardines would most likely likely have been incapacitated as a result of being hauled to the side of the vessel, and when released from the net they would have been washed ashore with the action of tide and waves.
Unethical behavior is rarely the result of selfish behavior is the <u>false </u>statement.
Explanation:
A person is said to behave unethically when he/she deviates from the moral set of values or ethical standards of behavior.
An unethical person often acts selfishly. Unethical behavior often tends to rationalize by stating that everyone does the same or considers his/her act is ethical and does not bother about the consequences of their activities and only bothers about self intentions.
Most of the commonly followed ethical behavior are almost followed by everyone as laws to promote the general well-being of all individuals in the society and the social harmony of the society.
These ethical laws help to resolve conflicts, follow rules, and behave in an organized manner.
As adults age, their dark adaption is slower; it takes longer to recover
their vision when going from a light to a dark area.
<h3>How does age affect dark adaptation?</h3>
- Results indicated that during human aging there is a dramatic slowing in a rod-mediated dark adaptation that can be attributed to delayed rhodopsin regeneration.
- Even in the absence of ocular disease, older adults have significant difficulty seeing in low light and at night.
- The severity of this issue cannot be explained by optical changes in the aging eye, such as pupillary miosis and increased lens density, and little is known about the neural basis of this issue.
- 94 adults between the ages of 20 and 80 had their dark adaptation functions measured in order to determine how quickly rod-mediated sensitivity recovered after being exposed to 98% bleach.
- In order to control for macular disease, fundus photography and a grading system were used to describe macular health in subjects over the age of 49.
