“…The increased enrichment in Kunduchi may be due to increasing human population, industrial and domestic effluents, and urban agriculture, which utilize inorganic fertilizers to boost production. Mangroves are increasingly being polluted (Machiwa, 1992;Machiwa, 2010), perturbed and cleared (Ajai and Chauhan, 2017), which decimates the value they play in terms of ecosystem services (Kimirei et al, 2016). While the data analysed in the current study are based on samples collected a decade ago, it has significance in assessing the role of population growth and anthropogenic pollution on nutrients pollution in mangroves (see Lugendo and Kimirei, 2021).…”

Caudal fin as a proxy for dorsal muscle for nutrient enrichment monitoring using stable isotope analysis: the case of Gerres filamentosus and G. oyena from mangrove creeks of Tanzania

The use of fish dorsal muscles in stable isotope studies, which is an invasive method that results in fish deaths, limits their applicability for rare and endangered fish species, as well as when large sample sizes and replicates are required, prompting research into feasible non-lethal sampling methods. The possibility of employing fin clippings (a non invasive approach) was investigated as a proxy for dorsal muscle in nutrient pollution monitoring studies using two common mangrove fish species, namely Gerres filamentosus and G. oyena, which are known to spend their early life stages primarily within mangroves. The dorsal muscles and caudal fin tissues of fish from the mangrove creeks of Kunduchi and Mbegani, Tanzania, were examined for 13C and 15N signatures. Dorsal muscles from Kunduchi (mean SD: 13C = -16.8 ± 2.86, 15N = 9.34±1.15) were more enriched than from Mbegani (mean SD: 13C = -18.60 ± 2.11, 15N = 7.27±1.09), and this enrichment was consistent across the two studied species. Caudal fins indicated similar enrichment trends. Fin tissue stable isotope values explained between 62 % and 87 % of dorsal muscle 13C and between 89 % and 98 % of dorsal muscle 15N variability. These findings support the use of fin-clipping as a non-lethal proxy for stable isotope analysis of the studied species for nutrient enrichment, and additional research into non-lethal sampling methods is recommended.

“…and wood (for house construction, fire, etc . ; Barbier, 2016; Carugati et al ., 2018; Chauhan, 2017; Jennerjahn et al ., 2017). Furthermore, because of their great biomass and capacity for accumulation of sediments, mangrove forests store more carbon than any other terrestrial environment (Costanza et al ., 2014) and protect coastal communities from erosion and flooding processes associated with storms and hurricanes (Feller et al ., 2017; Villate Daza et al ., 2020).…”

Asensio-Montesinos, F.; López-Rodríguez, F., and Anfuso, G., 2023. Marine litter impacting beaches and mangrove forests: a characterization and assessment within the archipelago of Jambelí, Ecuador. Journal of Coastal Research, 39(3), 431–441. Charlotte (North Carolina), ISSN 0749-0208.Litter abundance and composition were assessed at 13 sites in the Jambelí Archipelago, El Oro Province, Ecuador. The sites consisted of five beaches, which accounted for 82% of the total litter items, and eight mangrove forests, which accounted for the remaining 18%. Plastic was the most represented material on beaches and mangroves. Litter items were attributed to ocean-based sources, beach users, and aquaculture-related activities developed in the study area. Caps and lids, single-use plastics, rope, and strings were the most common items. A few sites presented similar litter composition because of their proximity and their connection through tidal channels. Authorities should focus more attention on beach litter by improving appropriate cleanup operations to enhance their environmental conditions and make them more attractive for tourism. Concerning mangrove forests, litter from aquaculture, fisheries, and tourism activities must be controlled and reduced.
