A scientist from the University of the Philippines (UP) divulged a patent for a semi-automated fish census system during a press conference held at Subic, Zambales.
A promising endeavor, this new tool could serve as a convenient way to assess the population density, species identification and biomass estimation of fish within an area—which are needed variables in discerning the success of reef rehabilitation and protection initiatives.
Dr. Laura T. David, a professor and scientist hailing from the UP Marine Sciences Institute, expressed that expeditions along the West Philippine Sea showed that the number of fish species and the abundance of fish have witnessed a dramatic drop between the years 1993-2019.
“A new patent has been developed that Filipinos should be proud of, though,” Dr. David stated. The patent in question is called the Fish-i, a fish census device based in the Philippines that could aid in the formulation of strategies for improving reef health and resilience, and assessing productivity of already existing strategies.
It is a great improvement from the traditional method used by projects such as the Indo Ocean Project, wherein a diver is involved. It relies on the divers’ skill in accurately counting and identifying fish, as well as accounting for divers’ fatigue.
Quite often, the fish’s behavioral response to the diver is also a distraction. The individual is often burdened with the decision to include or exclude a fish as it swims into or away from the chosen sample area.
To combat this, according to the official Fish-i website, their system consists of two major parts: a camera rig consisting of 2 to 8 cameras oriented parallel to the seabed for maximum scalability. It is mounted on a stand with 4 legs, and includes a video analyzer software that performs stereo analysis and image recognition on the collected videos.
Video clips containing estimates of fish size, density, and species diversity are the main outputs of the Fish-I. Through this method, minimal disturbance in the water is maintained.
Additionally, the stereo camera rig and fish video analyzer software are accessible to divers who can situate the system in any location, and examine its output at any given time.
Dr. David highlights that the Fish-i patent is one of the most important developments in regards to the addressing of sea level rise and its effects. She states that records of the census are available for later review and archiving.
