Florida – Day seven: Part two ðŸ‡ºðŸ‡¸

The Florida Files

After the talk we received from Jerry, we were quickly divided into two groups after stepping outside to enable us to carry out two different activities throughout the refuge.

This allowed us to smoothly alternate between the activities we were occupying at the time.

I noticed various resources during my visit at the reserve, even amongst the beach, issuing advice and key information to the public about different issues – including plastic use and its impact on marine life, whilst encouraging people to avoid littering as a method of keeping beaches clean and protecting animals.

The first activity we engaged in was shell collecting to allow us to complete a dichotomous key. We went shell collecting along the secluded beach to enable us to create a factual dichotomous key with a sample size of ten shells per group (working in small groups of three). Dichotomous keys are often used in an assortment of species identifications typically amongst zoologists and biologists.

The shells differed in their size, shape and colour which could serve as indicators to enable us to easily distinguish them all (similar to those carried out in animal behaviour studies) Some shells gathered were small and pointed, whereas others were larger and more rounded.

During the shell collecting activity, we learned the seriousness of taking shells off the beach and the fact it can result in severe punishments in the eyes of the Law. Shells were not to be excluded from the beach as they were closely protected. But Jerry’s licence, aswell as his profession as an educator to people of all ages, enabled us to gain the permission to do so.

Dichotomous key: A tool that allows the user to determine the identity of items in the natural world.

Seine fishing: A method of fishing that employs a fishing net that hangs vertically in the water with its bottom edge held down by weights and its top edge buoyed by floats. 

We became involved in a method of fishing named Seine fishing, where four individuals of the group would stand in the sea with a gigantic net, allowing them to easily encircle a variety of fish species.

The net was then dragged to land, myself and the other students (including teenagers from a local high school) had the job of picking the fish up from out of the net and placing them into an assortment of grey coloured treys.

The process was speedy, as we wanted to limit the number of species’ deaths during the experiment as a result of them remaining out of water for too long.

We categorised the fish to allow us to discover the frequency of the fish we had entangled within the net, with the aims of detecting whether some species appeared to be more abundant in comparison to others.

Throughout the duration of the experiment, we unfortunately experienced a mass of fish moralities due to accompanying reasons such as stress and heat exposure. In scientific research, moralities are expected due to many underlying factors. And the remainder of the fish were luckily freed back into their natural, open environment after the research had been carried out and recorded.

Seine fishing can withstand both pros and cons: It’s an excellent method for catching schools of fish, though the method can quickly become unsustainable if the population of that species cannot withstand it.
