Climate Change Vulnerability Assessment of the Eel Fishery in Aparri, Cagayan, Philippines

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.


Determining Sexual Development and Size at Sexual Maturity of Sardinella tawilis and its Implications on Management

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.

Species Composition, Relative Abundance, Distribution, and Size Structure of Spiny Lobsters (Panulirus spp.) in Eastern Visayas, Philippines

Spiny lobsters are an important resource of the artisanal fishery in Eastern Visayas, Philippines. It has long been harvested and contributes to the region's local economy.

Heavy Metals in the Striped Snakehead Murrel Channa striata and Sediments of Lake Mainit, Philippines with Notes on Piscine Micronuclei Occurrence

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).

Shell Dimension-Weight Relationship and Condition Index of the Invasive Mussel Mytella strigata in Sasmuan, Pampanga, Philippines

A total of 300 Mytella strigata were collected at three sampling points in the mussel coastal demonstration farm in Sasmuan, Pampanga, and subjected to morphometric and gravimetric measurements for the evaluation of its growth pattern and condition index.

Phenotypic Variability in Dorsal-fin Rays of Rachycentron canadum (Linnaeus, 1766) from Western, Visayas, Philippines

Cobia, Rachycentron canadum, is the only species in the family of Rachycentridae. Cobia is typically characterized as having 26–33 dorsal-fin rays.

Abundance and Distribution of the Larvae of Family Carangidae in the Philippine Waters

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.


Addressing Food Security in Batangas, Philippines through Backyard Tilapia Farming

The onset of the COVID-19 pandemic showed how food supply could become unstable when lockdowns and curfews hamper transportation and delivery logistics.
