Comprehensive Guide to Aquaculture: History, Methods, and Industry Opportunities
Historical Development of Scientific Fish Farming
The development of the aquaculture industry in the country has followed a specific chronological progression, beginning with early experimentation and leading to the establishment of major research bodies.
Timeline of Development
1940: Scientific fish farming is considered to have officially started in the country with initial experiments conducted on milkfish culture. F
The 1960s: This decade saw the application of improved milkfish culture techniques throughout the industry.
The early 1970s: National and international research institutions were established to provide further support and scientific backing to the burgeoning fish culture industry.
Pioneers of the Industry
Dr. Pio Valencia: Recognized as the pioneer of fish culture specifically in the Visayas region.
Talava: Credited as the pioneer of oyster culture within the country.
Leading Aquaculture Research Centers
Southeast Asian Fisheries Development Center (SEAFDEC): Specifically the Aquaculture Department located in Tigbuan, Iloilo.
International Center for Living Aquatic Resources Management (ICLARM): Located in Makati.
Central Luzon State University (CLSU): Hosts the Freshwater Aquaculture Center in Nueva Ecija.
University of the Philippines (UP): Operates the Brackishwater Aquaculture Center.
Fish Species and Cultivation Habitats
Fish species are categorized based on the salinity and environment of the water in which they are reared.
Freshwater Culture
Commonly cultured species in freshwaters include:
Tilapia.
Carp.
Catfish.
Mudfish.
Gourami.
Brackishwater Culture
Brackishwater ponds are primarily used for the cultivation of the most important commercial species:
Milkfish.
Prawns.
Marine Species Culture
The culture of marine species is currently categorized as being in the experimental stage.
To date, only a few marine species have been successfully reared in ponds and pens.
Systems and Methods of Fish Culture
There are five primary methods used for the rearing and management of fish populations.
1. Pond Culture
This is the most common method of fish culture.
It involves maintaining water in an enclosed area through the artificial construction of a dike or bund.
2. Cage Culture
This method involves the rearing of fish from the juvenile stage until they reach commercial size.
The fish are kept within a volume of water that is enclosed on all sides.
3. Pen Culture
This refers to the raising of fish in a volume of water enclosed on all sides except for the bottom.
This system is considered a hybrid between pond culture and cage culture.
4. Raceway Culture
This involves the raising of fish in running water.
Raceways are specifically designed to provide a flow-through system.
Purpose: The continuous flow enables the rearing of a much denser population of fishes compared to static systems.
5. Recirculating Aquaculture System (RAS)
An aquaculture system that incorporates the treatment and reuse of water.
Standard: A true recirculating system is defined as one where less than of the total water volume is replaced per day.
