Name: Quency Galvez Course/Year/Section: BSF 4 REACTION PAPER ( AGRI RESEARCH) “Research is a way to prove lies and support truths.” In the unit 1 of Agri research, I’ve learned a lot after reading it. My realization about this unit is on how important the research is in our daily life. I gained deeper understanding in scientific process. At the same time in reading the given lesson I learned on how to find the results and writing grants about the chosen topic. We can discover and innovate something that can be beneficial or not to our community. The topics in this unit is very interesting because it gave me a lesson and idea on how to formulate our thesis. It also includes the different kinds and characteristics of a research according to its purpose, by this we can easily identify if what we are going to use in conducting our thesis. And not only for the purpose of the research but also the goal, level of investigation, choice of answers to the problem, time allotment and its statistical content. Therefore, the lessons tackled in the unit one is very important to study and understand because we can easily choose a topic and formulate this if we can understand well the given lesson. We can explore and create a new product because of research, that’s how important the research is. Shark Behaviour and Marine Faunal Assemblage beneath Smart Drumlines This study was written by Rick et al., last August 2, 2021 at Southern Cross University, Australia. This article contained a topic about the behavior of shark and marine faunal. The researchers used a technique which allows the relocation and capture of white sharks, bull sharks and tiger sharks, it is being called a SMART technique (Shark-Management-Alert- in-Real Time). This SMART technique is a technology which includes a smart drumlines VR4G shark listening station, aerial surveillance using helicopters and drones as well as tagging sharks to understand their movements and presence close to shore. To observe the behavior of the sharks and their interactions to other marine fauna the researchers of this study used some technologies and a SMART technique. According to Chapman and McPhee shark bite hotspots, like coastal Australia, USA, South Africa, Reunion Island and The Bahamas have experienced increasing numbers of unprovoked shark bites on people over the last thirty years. Mesh nets, or shark nets, are a rectangular web of netting suspended in the water and held in a vertical orientation by buoys and anchors. Drumlines are a baited hook suspended from a large floatation buoy secured in place by an anchor. Both of these tools aim to reduce local populations of shark species, such as white sharks (Carcharodon carcharias), bull sharks (Carcharias leucas) and tiger sharks (Galeocerdo cuvier) because these three species are implicated in the majority of bites worldwide. SMART drumlines were implemented in New South Wales, Australia, in response to rising public concerns after a spike in shark bites between 2014 and 2015. Currently, little is known about the types of marine animals attracted to SMART drumlines. Evidence about behaviours and interactions is consequently required to improve the ability of SMART drumlines to maximize catch of target sharks while minimizing impacts to other marine fauna. The researchers proved that using the novel approach of deploying video cameras beneath SMART drumlines, we quantified marine faunal assemblages and recorded the behaviour of sharks attracted to an opportunistic food source. While assemblages of marine fauna varied between locations, there was limited interaction between bycatch species (especially threatened or protected species) and the SMART drumlines. It is, therefore, likely that while still capturing target sharks SMART drumlines have relatively low bycatch and mortality rates, particularly in contrast with their standard fishing gear counterparts. White sharks were more likely to successfully bite the bait than whaler or hammerhead sharks, resulting in white sharks being more frequently caught, tagged, and released (Tate et al., 2021). Despite being an invasive approach to shark bite mitigation, SMART drumlines appear to be relatively sustainable and an effective tool for catching target shark species, while minimizing bycatch. Therefore, sea surface temperature significantly affected marine faunal assemblages. Few sharks were threatened, endangered or protected species were observed. The SMART technique has been proved that it is an effective technology in understanding the behavior of the sharks.
