Philippine Journal of Science, 2013 - Science and Technology Information InstituteThree stream sections (upstream, midstream, and downstream) of Tayabas River, Philippines were surveyed during the wet and dry seasons of 2010 to evaluate the poorly known status of freshwater fish assemblages. The study collected a total of 1,070 individuals comprising 15 species, 13 genera, and 8 families. The three most abundant groups were poeciliids (61.85%), gobiids (26.16%), and cichlid (5.51%). Shannon-Weiner’s diversity indices ranged from 1.270 to 2.171. Relatively high Shannon evenness indices (0.653–0.846) and low Simpson’s dominance values (0.142–0.322) were calculated implying a fairly equitable distribution of niche space for dominant and non-dominant fishes. Significant change on fish assemblage in longitudinal gradient was observed (p<0.05), being the most diverse fish assemblage registered in the upstream. Species richness is mostly composed of native fish species (10 species) and mainly represented by stream gobiids (six species). The downstream, however, had the highest cumulative abundance, in which the larger proportion was from introduced species. Also, wet season had considerably more fish species and individuals relative to dry season (p<0.05). This significant spatio-temporal differences in fish assemblage data were evaluated by multivariate analyses (p<0.05). Canonical correspondence analysis identified the depth (seasonal water level fluctuations), vegetation growth, and dissolved oxygen concentrations (in order of importance) as the most influential environmental parameters affecting fish assemblage structure. Also, climatic stress (prolonged drought) and anthropogenically-induced habitat alteration could negatively affect the integrity of freshwater fishes within the river. The study suggests extensive management programs of the river for the protection of native fish species.
Establishing adaptive strategies towards a climate-resilient seaweed farming: A case in Panobolon Island, Guimaras, Philippines RJG Castel -
Fish for the People, 2018 - Secretariat, Southeast Asian Fisheries Development CenterSeaweeds are ecologically important primary producers, competitors, and ecosystem engineers (Harley et al., 2012), support complex food webs in coastal zones, and provide habitats and food for associated organisms, from apex predators to invertebrates (Reisewitz, Estes, & Simenstad, 2006). Seaweeds are intimately linked to human cultural and economic systems via the provision of ecosystem goods and services ranging from food, medicine, to cosmetics (Pickering, 2006) and storm protection (Rönnbäck, et al., 2007). There is strong scientiﬁc consensus that coastal marine ecosystems, along with the goods and services they provide, are threatened by anthropogenic global climate change (IPCC, 2001). However, the impacts of ongoing and future anthropogenic climate change in seaweeddominated ecosystems remain poorly understood (Harley et al., 2012). It is therefore, timely and relevant to provide better understanding of the experiences of seaweed farmers and their capacity to anticipate, cope with, resist, and recover from the impact of natural hazards (Blaikie, Cannon, Davis, & Wisner, 1994). The Philippine-based SEAFDEC/AQD is currently conducting a three-year (2015-2018) study on the economic benefits and losses of seaweed farming due to climate change indicators. With pilot site in Panobolon Island, Nueva Valencia, Guimaras, Philippines, the study highlights the adaptive strategies and the effects of climatic change on the productivity of small-scale seaweed growers in a community.
