Internal Cycle of Seminars at IMEDEA (CISI) consist on a cycle of seminar presentations given mainly by doctoral students, masters and junior postdocs, although it is not closed to other staff, such as visitors and staff, that take place every Friday from 4:00 p.m. to 4:30 p.m in the seminar room os IMEDEA.

This represents a great opportunity to learn more about the research carried out at the Institute and to bring those with less experience , the chance of increasing their presentation and public speaking skills. Afterwards, there will be soft drinks and beers for all attendees 😉 We strongly encourage you to participate. Join us!

Internal Cycle of Seminars IMEDEA - Amaya Álvarez- «Deep Learning inside the fish market»
  Abstract In this presentation, we will explore the various tasks undertaken by the Fish Ecology Lab at the Palma Fish Market since 2018. Our focus lies in automating the processes employed for extracting fish length measurements. The dynamic distribution of fish lengths plays a crucial role, not only in making informed short-term operational decisions within a fishery co-management framework but also in providing input for traditional fishery models that illuminate mid- and long-term trends in exploited stocks. Traditionally, the estimation of fish length in most fisheries has been a manual endeavor, resulting in precise measurements at the individual fish level. However, due to the high cost and inefficiency associated with supervised sampling, the sample size tends to be limited. Consequently, the precision of population-level estimates often falls short, and biases may arise, especially when adequately stratified sampling programs are economically unfeasible. Conversely, the application of machine learning and artificial intelligence in fisheries science presents a promising avenue for large-scale, unbiased sampling of fish catches. The Fish Ecology Lab has been working with the daily images recived from the auction of the fish market to extract information on various commercial species such as hake, dolphinfish, and red shrimp. This presentation will specifically focus into the deep learning techniques employed for each of these cases.

Internal Cycle of Seminars IMEDEA - Andrea Tribulato «Macrofouling community of a Building with Nature solution for coastal protection: a comparison of animal settlement between mangrove trunks and bamboo poles»

25/01/2024

 

Abstract: 

Mangrove deforestation and land subsidence have led to significant challenges such as coastal floods and retreat in northern Java. To address these issues, a large-scale Building with Nature (BwN) solution is being implemented by re-establishing a mangrove forest that acts as a coastal defence. Large semi-permeable bamboo dams are being built to facilitate natural mangrove recruitment by accumulating sediments and creating a habitat for the trees. The ecosystem that grows on these bamboo artificial structures and its effect on the surrounding ecosystem has not yet been fully studied. Within this context, we set up a three-month field experiment in which we looked at the development of a macrofouling community on bamboo poles and mangrove Avicennia marina trees, and the effect of the BwN structure on the development of such communities. We observed that bamboo poles get colonized faster and support a different community than mangrove trunks. Mangrove trees were colonized mostly by Ostreidae whereas bamboo poles by Amphibalanus. Percentage coverage was consistently higher on bamboo poles. Additionally, we observed lower coverage in the location affected by the semi-permeable barrier compared to locations that were not, potentially due to the sediments trapped by the barrier which may impede larval settlement. Lastly, we discuss the idea that the structure and its ecosystem may have a nutrient enrichment effect, potentially influencing mangrove tree resilience to strong winds. Our findings contribute insights into the ecological functions and implications of these BwN structures in the marine environment, emphasizing the importance of considering their broader impacts on mangrove ecosystems.
