The mangrove red snapper Lutjanus argentimaculatus (Forsskål 1775) is a high value, euryhaline marine fish with potential as a species for freshwater aquaculture.


Policy Brief 

New Scales to Guide the Assessment of Hard Coral Cover and Diversity in the Philippines

Key Points
  • Coral reefs supply vital ecosystem services to the Philippines.
  • Safeguarding these services requires the rapid identification of reefs that provide most services, and identification is best made by measuring hard coral cover and diversity and using updated and locally relevant assessment scales on these measurements.
  • The use of these assessment scales has advantages and is recommended to update and improve Philippine laws.

Reproductive Biological Performance of Otolithes ruber (Bloch and Schneider 1801) in San Miguel Bay, Philippines

The tigertooth croaker, Otolithes ruber (Bloch and Schneider 1801), was studied to determine its reproductive biology characteristics for 34 months from March 2015 to November 2017.


Value Chain Analysis of Maliputo, Caranx ignobilis in the Philippines

This value chain analysis study was conducted to understand the industry, to identify the key actors, supply and value chain, and to identify issues and concerns to support the development of C. ignobilis industry.

Gender Participation in the Fisheries Sector of Lake Taal, Philippines

Lake Taal is a source of livelihood and provides for more than 2,000 sustenance fisherfolk. Fish production of the open water fisheries has dwindled over the years with the continuous decline of fish catch, which can be attributed to unsustainable fishing practices such as illegal fishing, overfishing, pollution, and the expansion of aquaculture activities in the lake.

Parasitic Anisakid Nematode Isolated from Stranded Fraser’s Dolphin (Lagenodelphis hosei Fraser, 1956) from Central Philippine Waters

Cetaceans, including dolphins, serve as definitive hosts of zoonotic anisakid nematodes, which are important etiological agents for human anisakiasis and allergy-associated health risks.

Microbial Community Response to Carbon-Nitrogen Ratio Manipulation in Biofloc Culture

Biofloc technology (BFT) is an alternative aquaculture practice that involves the manipulation of carbon-nitrogen ratio (C:N) to manage nitrogenous waste through microbial assimilation.

Does the Behavioral Stress Response of Nile Tilapia, Oreochromis niloticus Breeders During Isolation Influence Seed Production?

This experiment assessed the effect of breeder’s behavioral stress response [i.e., eye color pattern (ECP)] during isolation on O. niloticus seed production. ECP change was marked by fractional color changes of the iris and sclera, which was transformed into scores ranging from 0 (no darkening) to 8 (total darkening).

Assessment on the Occurrence of Anisakid and other Endoparasitic Nematodes Infecting Commercially-Important Fishes at Tayabas Bay

Anisakid nematodes are parasites commonly present in the marine environment. Parasites belonging to the family Anisakidae or the genus Anisakis can cause two different clinical manifestations: gastrointestinal disorders and allergic reactions known as anisakiasis.

Phytogenics in Aquaculture: A Short Review of Their Effects on Gut Health and Microflora in Fish

Increasing pace in aquaculture development to meet the growing food requirements of the population has greatly compromised the carrying capacity of the culture environment and has placed the aquacultured animals at heightened risk of getting diseases due to pathogens.

Abundance, Distribution, and Diversity of Tuna Larvae (Family Scombridae) in the Philippine waters

The Philippines is a significant producer of tunas globally but has experienced a decline in tuna production in recent years. Thus, efforts to explore and assess new fishing grounds were conducted by the Bureau of Fisheries and Aquatic Resources (BFAR) through M/V DA-BFAR.


Status of Water Quality in Fishponds Surrounding Manila Bay

Fishponds around Manila Bay contributed an average of 41.19% of the total aquaculture production in the country. However, massive productions entail the intensification of ponds, which resulted in water quality deterioration.
