A spatio-temporal study on the abundance of the Carangidae larvae in Philippine waters was conducted to minimize the lack of information on their spawning grounds. The study analyzed fish larvae data from M/V DA-BFAR cruises between 2006 and 2018, covering various areas in the Philippines.

Lake Mainit is the deepest lake in the Philippines, with sporadic documentation of various types of aquatic pollution. This paper reports the heavy metal content in the muscles of the striped snakehead murell Channa striata and bottom sediments from five stations across Lake Mainit using quadrupole-inductively coupled plasma-mass spectrometry (Q-ICP-MS).

Reproductive biology is important in formulating management interventions for fish stocks. Limits on catch size are established based on the identified size at first sexual maturity of the target fish species, which can be accurately determined through histological analysis of gonads.

The global glass eel population is continuously declining over the years. Apart from the anthropogenic factors, the global production decline suggests that the changing climatic condition may have influenced its downtrend.
Market patterns and conditions can affect the economic value of fishery commodities; hence, they can contribute to postharvest losses.
Age and growth dynamics of Conomurex luhuanus were investigated to determine the population structure.
Monitoring changes in fish density and biomass inside marine protected areas (MPAs) through fish visual census (FVC) can determine if MPAs are achieving their goal of promoting fish population recovery.
“Ludong”, also known as the president’s fish, is a river mullet known to be found in Cagayan River, Northern Philippines. Unfortunately, this species has been heavily exploited over the years.
Leyte Gulf is an important fishing ground in the Philippines that serves as a livelihood and food source for many coastal communities.
Sea cucumber fishery is a significant livelihood in the Philippines; however, overexploitation and inadequate management programs resulted in the decline of various sea cucumber species.
There were reports of the existence of horseshoe crabs in Palawan, Philippines, but there is a need to identify and confirm these species.
This study provided the first report on the reproductive biology of the redtail scad, Decapterus kurroides.
- Very little is known about harmful jellyfish species in the Philippines, much less about their impacts on society (e.g., fishing and tourism sectors, local community).
- The Department of Agriculture - Bureau of Fisheries and Aquatic Resources (DA-BFAR), Department of Environment and Natural Resources (DENR), Departments of Health (DOH) and Tourism (DOT) together with the Department of Science and Technology – Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (DOST-PCAARRD), other research institutions and academe, should conduct more research related to harmful jellyfish species to address the paucity in information.
- To reduce injuries and deaths resulting from harmful jellyfish envenomation, DA, DENR, DOH, and DOT, and their counterparts in local governments must strengthen their information and education campaigns, preventive measures, emergency response, and treatment of jellyfish-related injuries and stings.
- DA-BFAR should monitor box and other harmful jellyfishes in collaboration with the local governments with high coastal tourism traffic. This monitoring should be made participatory in high tourism-traffic areas, involving members of the public, the fisheries, tourism, and health sectors of the local governments in coordination with local academic institutions.
- DA-BFAR and DENR should also maintain a publicly available database of jellyfish envenomation dates, times, and locations. Health workers and law enforcement officials should be taught to recognize the stings and record casualties for the DA-BFAR and DENR databases. This database and monitoring could be the basis for a national risk map and calendar and, eventually, an advisory and warning system.
- Artificial habitat projects are expensive endeavors that should be carefully designed and planned to be sustainable and effective.
- Artificial habitats must be implemented with other fisheries enhancement and management measures and be monitored to allow for future improvements in site selection criteria and design.
- Coral reef rehabilitation is much more expensive than protection.
- Given the considerable cost and effort involved, artificial habitat deployments are justified in only a few situations. The lessons shared in this brief contain recommendations for the review and amendment of the joint memorandum concerning the use and management of artificial reefs.
