Diving Deep: Our First Hands-On Reef Survey Training with Dr. Mwaura

Yesterday marked a significant milestone for our local fishing community as we launched into our first in-person reef survey training session, led by Dr. Mwaura from the KMFRI Research Institute. This initiative is part of our ongoing commitment to not only understand but actively participate in the preservation of our marine ecosystems.

A Day of Learning and Preparation:

Dr. Mwaura introduced our group to essential survey techniques, focusing on how to effectively use 50-meter transects to assess reef health. The fishermen, equipped with underwater slates, were trained to record data on fish community abundance and benthic cover, including corals, which are critical to understanding the overall vitality of our reefs.

Laying Foundations: Engaging BMU members at our first theory session in Kwa Chambo, setting the stage for effective reef conservation.

Practical Skills in Action:

Our session was split into comprehensive training segments—starting with a theoretical overview and followed by practical in-water exercises. We practiced placing transects and collecting preliminary data, gearing up for today’s session where we finalized our techniques in preparation for tomorrow’s full-scale survey. One team is set to capture detailed benthic data through photographs taken every two meters along the transect, while another will focus on fish data, observing 2.5 meters on either side of the transect.

Precision in Practice: Thomas meticulously setting a 50m transect as part of our reef survey preparations.

The Role of Our Fishermen:

The expertise of our fishermen is invaluable. They not only guide us to the nearest reefs but also share their extensive knowledge of the local fish species, enhancing the accuracy and relevance of our data. Their insights are crucial as we strive to assess and subsequently protect these underwater habitats.

Roots of Recovery: Exploring our sea grass nursery off Bofa Beach, a vital part of our marine restoration efforts.

Anticipated Marine Life:

During our surveys, we are particularly keen to spot several key indicator species, known for their ecological roles and commercial importance:

• Lethrinidae (Emperors) and Lutjanidae (Snappers) as primary fishery targets.

• Siganidae (Rabbitfish) and Acanthuridae (Naso/unicorn fishes), vital herbivores that help maintain algal balance.

• Scarinae (Parrotfishes) and Chaetodontidae (Butterflyfishes), indicators of healthy coral cover.

• Epinephilidae (Groupers), Sharks, and Napoleon wrasse, which are top predators and vulnerable species critical to marine biodiversity.

  
  

Looking Forward:

With the theory behind us and practice sessions completed, we are set to embark on our boat tomorrow for the actual reef survey. The timing is meticulously planned to coincide with the low tide at 1:11 PM, optimizing conditions for our research.

Strategizing Success: Our team in deep discussion, planning the specifics of tomorrow’s crucial reef survey.

Conclusion:

This survey is more than just a data collection exercise; it's a step forward in empowering our community with the knowledge and skills to actively contribute to marine conservation. Through these efforts, we aim to develop informed strategies to safeguard our beloved reefs.
