Body size and environmental prey availability are both key factors determining feeding habits of gape-limited fish predators. However, our understanding their interactive or relative effects is still limited. In this study, we performed quantitative dietary analysis different body sizes goby (Gymnogobius isaza) specimens collected from Lake Biwa between 1962 2004. First, report that the diet was composed mainly zooplankton (cladocerans copepods) before 1980s, thereafter, shifted to...
Otoliths, crucial tools for understanding fish biology and ecology, offer valuable insights into fisheries science in Southeast Asia. Traditionally used age identification through shape analysis growth ring counting, otolith studies have evolved to encompass broader ecological investigations. This review synthesizes literature on otoliths Asia identify research gaps suggest future directions. Utilizing targeted keywords, we mined data from scientific search engines, focusing peer-reviewed...
Long-term time-series data have been proven useful in analyzing the adaptability of zooplankton communities as a response to environmental change. The unique life history and importance aquatic ecosystems, coupled with capability lakes integrate changes surrounding watershed, has given each recognition “beacons sentinels climate change,” respectively. Aside from this, many undergone pollution through human-induced eutrophication attributed extensive lake-shore town development, agricultural...
Biological invasions caused by the introductions of non-native species (NNS) into their non- native ecosystems have long been a global environmental concern. In Philippines large-scale importation freshwater fish for aquarium and aquaculture industry documented as early 1940s. However, little invasiveness assessment has done in past, which resulted to invasion some these exotic species. Thus, this paper, 25 NNS (Order: Siluriformes) were assessed using Aquatic Species Invasiveness Screening...
Unsustainable urbanization in the Indo-Pacific continues to threaten terrestrial and aquatic ecosystems due habitat disturbances driven by human pressures. The Marikina Watershed, one of most critical watersheds Philippines, has been exposed economic population growth resulting landscape modification water quality degradation. This led establishment Upper River Basin Protected Landscape (UMRBPL) rehabilitate watershed ecosystem. To strengthen this conservation initiative, we aimed assess...
Moringa (Moringa oleifera Lam.) is commonly known to Filipinos as “Malunggay”. This tree abundant in the rural areas, and a rich source of digestible protein, vitamins minerals, which are essential components animal feeds. Thus, it has great potential feed resource, especially for livestock poultry smallholder farmers. Using species, feeding experiments were conducted determine effects moringa on growth performance goats broiler chickens; laying chickens quails quality their eggs. A...
Summary Three acanthocephalan parasites, namely Neoechinorhynchus (Neoechinorhynchus) quinghaiensis, Rhadinorhynchus ganapatti, and Bolbosoma sp. are reported for the first time from Philippine fishes. N. (N.) quinghaiensis (Neoechinorhynchidae) may have been introduced into country through importation of carp species China, where this parasite was described is presumed to be naturally occurring. The adult worms R. ganapatti isolated cystacanth represent record parasites both family...
Our knowledge about the food habits of sea snakes and how it is associated with their distribution has seen much development through its description across a number species available published literature except for key threatened such as Hydrophis semperi. This paper aims to describe H. semperi gut content stable isotope analyses. We also compared data Little File Snake, Acrochordus granulatus, sympatric Recorded captures suggest that snake tends occur in littoral zones shallower portions...
The interface between lakes and their outlet rivers is an interesting research site for fish community dynamics because it immediately exposed to disturbances in lake ecosystems. In this paper, observations on the species composition, dietary habits distribution of upstream area Pansipit River - sole Lake Taal, were presented. Fish samples comprised juvenile from 12 species, including four that introduced. These non-native more abundant than native caught. Dietary analyses suggest have a...
Lake Taal is one of the most significant lake ecosystems in tropical East Asia. In 2011, a review paper consolidated all known biodiversity and limno-ecological studies conducted from beginning 20th century way to late 2000s. It highlighted that insufficient funding, inadequate long-term monitoring data, publication culture time impeded having comprehensive understanding lake. Since then, much research work has been done Taal, especially during past decade. This provides an analysis summary...
One hundred eighty-three individuals of Glossogobius aureus, native to Lake Taal, Philippines, were collected in 2021–2022. Of these, 4 endohelminths found and identified: Andracantha gravida (Acanthocephala: Polymorphidae), Schyzocotyle acheilognathi (Platyhelminthes: Bothriocephalidae), Azygia sp. Azygiidae), Opegaster minima Opecoelidae). These helminths represent new host records for G. aureus provide novel contributions the recent Philippine parasite biodiversity listing. Among these...
Abstract Purpose. The spread of invasive and endemic parasites in the Philippines, along with co-introduction alien fish species (IAFS), could threaten country’s local fauna, as well pose socio-economic public health concerns. However, due to scarcity knowledge about country, this incidence remains poorly understood. Thus, study aims explore parasitic diversity common IAFS within Marikina River system. Methods. Isolated helminthic endo-parasites from samples were processed for morphological...
