How to annoy barracudas using Baited Remote Underwater Video. This one popped in after an hour of no fish at all, so it made me especially happy.

Originally published in omaliprincipeen.weebly.com, More info here From the 28th of May until the 8th of June Omali Vida Nón did the first histological analysis of the gonad samples of Lutjanus fulgens that had been collected in Principe during April and May 2018. This is part of the fish maturity study conducted in partnership with Forever Principe, so as to better understand the reproductive biology of this predatory species and inform fisheries management. The histological analysis was conducted at Prof. Charles Tyler’s lab at the University of Exeter, under the supervision of Dr. Anke Lange. Samples are fixed in wax, sliced in the microtome and stained on haematoxylin-eosin, and then analysed on the microscope. Through this analysis we aim to validate the macroscopic assessment of the maturity of the gonads done in the field and understand the gonad development and maturation for this understudied species.  Originally published in omaliprincipeen.weebly.com, know more here BRUV surveys are starting again! We are using Baited Remote Underwater Cameras around Principe Island to understand spatial patterns of fish distribution, information that will be used to inform management of Principe’s fisheries. In May we did some fieldwork and were able to get interesting footage as well as refining the protocol for deploying the BRUV devices. Below you can watch a short film showing all the steps for deploying the cameras, as well as some of the species identified on camera. This study is funded by Darwin Initiative, Halpin Trust and Forever Príncipe. Thanks to all funders! |
