Defined as waters landward of archipelagic baselines not part of Archipelagic Waters.
Philippines claims sovereignty over these waters, including airspace and seabed, as outlined in UNCLOS.

Archipelagic Waters

Refers to waters on the landward side of archipelagic straight baselines.
Governed by the "Archipelagic Doctrine", recognizing archipelagos as sovereign units.

Territorial Sea

Extends 12 nautical miles from baselines surrounding the Philippine archipelago.
Sovereignty includes airspace, seabed, and subsoil under UNCLOS guidelines.
Fisheries Management Areas (FMAs) are delineated with FMA 5 covering 483,417 sq. km and FMA 6 covering 293,930 sq. km, encompassing a large part of the West Philippine Sea.

Fisheries Objectives and Management

Focus on participatory governance for sustainable fisheries management.
Emphasis on ecosystems approach to food security.
Aims to provide supplementary livelihood opportunities in line with the Amended Fisheries Code.
Encourages cooperation among local governments, national agencies, and stakeholders.

Municipal Fishing

Defined as fishing operations using boats of 3 gross tons or less or no boat at all, mostly for sustenance.
Includes inland fishing in freshwater bodies, such as lakes and reservoirs.
Regulated by local governments and supported by nearly 500,000 ha of inland water bodies.

Commercial Fishing Operations

FAD-based fisheries include master fishers, boat captains, and divers, who possess extensive knowledge of fishing practices and fish behavior.
Roles include overseeing operations, navigation, monitoring fish biomass, and net deployment.

Tuna Handline Crew Structure

Two main types of handline fishers: palaran (in municipal waters) and pamariles (in distant waters).
Fishing vessels vary in size with capacities for 8 to 20 crew members.
Each vessel requires a captain and chief mechanic for effective operation.

Registration and Licensing for Commercial Fisheries

Certificate of Ownership (CO) establishes legal ownership of fishing vessels and contains specific vessel information.
Certificate of Philippine Registry (CPR) registers vessels under the Philippine flag without a validity period unless ownership changes.
Shipstation License assigns communication frequencies and ensures compliance for maritime vessels.

Global Fishing Fleet Overview

Africa's fishing fleet comprised over 19% of global vessels in 2022, increasing from 18% in 2019.
Motorized vessels account for approximately 3.3 million, about two-thirds of the global fleet, a slight decline from a peak of 3.5 million in 2020.
Non-motorized vessels decreased from 2 million in 1995 to 1.6 million in 2022.

Regional Vessel Distribution

Asia leads with 80% of global motorized vessels and 54% of non-motorized vessels as of 2022.
Africa holds 42% of the world's non-motorized fleet, collectively with Asia representing 96% of this category.

Vessel Size Distribution

Size data available for only 37% of the global fleet, with 89% of known vessels measuring under 12 m overall length.
Information is not available for major fishing nations like China, Indonesia, and the Philippines, which together account for nearly half of the global fishing fleet.

Other Tools of Taxonomy

Key aspects include behavior, physiological differences, and diet.

Systematics vs. Taxonomy

Systematics encompasses scientific naming, description, preservation, classification, identification, distribution data, evolutionary history, and environmental adaptations.
Taxonomy focuses on naming, describing, preserving collections, and classification of organisms.
Classical taxonomy, originating with Plato and Aristotle, relies on morphological traits.
Modern taxonomy, termed new systematics by Julian Huxley, integrates various biological characters beyond morphology, including genetics and ecology.

History of Biological Classification

Hunter-gatherer classifications based on edibility, taste, habitat, and danger.
Aristotle classified living organisms, forming the basis for current taxonomy.
Carolus Linnaeus introduced binomial nomenclature, establishing a two-part naming system for species in "Species Plantarum" and "Systema Naturae."

Fish Systematics

Fish systematics is the study of fish diversification and classification.
Branches of systematics include numerical (biostatistical methods), biochemical (analysis of protoplasm), and experimental (evolutionary units).

Contemporary Fish Systematics

Mainly relies on morphological traits; environmental effects can complicate strain identification.
DNA analysis of mitochondrial genomes provides insights into evolutionary relationships and species origins.

Component Fields of Systematics

Biodiversity: Studying variety and quantity of organisms.
Taxonomy: Describing organisms’ attributes.
Classification: Organizing organisms into hierarchical groups.
Nomenclature: Naming organisms.
Biogeography: Analyzing organism distribution and abundance.
Evolutionary Biology: Classifying based on phylogenetic relationships.

Freshwater Fish Diversity

Over 32,500 fish species; more than 15,000 are freshwater species.
Freshwater fish represent about 25% of vertebrate biodiversity.
Average of 305 new fish species described annually since 1976.
Major freshwater fish families: Cyprinidae, Gobiidae, Cichlidae, Characidae, Loricariidae, Balitoridae.

Biogeography of Rhinogobius Species

Highlights geographical influences on species classification.

Binomial Nomenclature

Linnaeus’ two-part naming system provides a universal identification method, reducing confusion from various common names.
Scientific names are in Latin, facilitating international communication in science.

Importance of Scientific Naming

Universal coding system avoids common name confusion.
Names are derived from the species’ genus, descriptors, discoverers, and places of discovery.

IUCN Red List Overview

The IUCN Red List is an inventory of species' conservation status, established in 1964.
It serves as an essential indicator of global biodiversity health and extinction risk.
Provides crucial information on species range, population size, habitat, threats, and conservation actions.

Red List Index (RLI)

RLI tracks trends in overall extinction risk for various species.
RLI value of 1.0 indicates all species are classified as Least Concern.
A constant RLI value over time implies unchanged overall extinction risk for a group.
Rapidly increasing extinction risk among coral species noted.

Importance of the IUCN Red List

Informs and catalyzes action for biodiversity conservation and policy changes.
Guides decision-making processes related to biodiversity and resource allocation.
Used by governments to monitor progress towards biodiversity targets.
Improves conservation planning by identifying Key Biodiversity Areas.
Raises awareness about biodiversity and its impact on human health and livelihoods.

Categories of the IUCN Red List

Extinct (EX): No surviving individuals; example includes endemic cyprinid fishes from Lake Lanao, 15 out of 17 species are extinct due to non-native species introduction.
Extinct in the Wild (EW): Species surviving only in captivity; for instance, Dabry's sturgeon (Acipenser dabryanus) from the Yangtze River Basin faces drastic population decline due to overfishing.
Not Evaluated (NE): Nearly 1.9 million species described but not yet assessed by IUCN.

Philippine Red List and PARLC

The Philippine Red List Committee was formed to assess wildlife conservation status.
The Philippine Aquatic Red List Committee (PARLC) establishes criteria for aquatic species classification.
PARLC prioritizes the establishment of critical habitat based on scientific data and established criteria.

Sub-committees within PARLC

Focus areas include freshwater bony fishes, marine invertebrates, pelagic and demersal fishes, aquatic snakes, cetaceans, and aquatic plants.

Recent Assessments

As of December 2023, PARLC assessed and published the status of 85 freshwater fishes in the Philippines, highlighting species like the Philippine medaka, which is endemic to Northern Luzon and has a limited distribution.
Conservation efforts aim to assess population status and habitat conditions for prioritizing conservation and restoration efforts.

Fish Port Complexes in the Philippines

Navotas Fish Port Complex (NFPC): Premier fish center in the Philippines, one of the largest in Asia, managed by the Philippine Fisheries Development Authority (PFDA). Acts as a landing site for commercial fishing boats.
General Santos Fish Port Complex (GSFPC): Key infrastructure for the East Asia Growth Area (EAGA), crucial for post-harvest fish processing in Mindanao.
Davao Fish Port Complex (DFPC): Seventh commercial fish port managed by PFDA, significant for the Mindanao region.
Zamboanga Fish Port Complex (ZFPC): Establishes a systematic fish marketing and distribution system, supported by international funding, enhancing regional fishing industry operations.

Coastal Areas in the Philippines

Over half of the municipalities (54%) are coastal, with almost all major cities located in these areas.
62% of the Philippine population resides in coastal zones, heavily relying on marine fisheries for over 50% of their animal protein intake.
Coastal areas face rapid population growth and widespread poverty, compounding challenges like declining fisheries productivity due to overharvesting.
Pollution from various activities is detrimental to marine environments, affecting water quality and fish health.
Global climate change poses serious risks to coral reefs and associated fisheries.

Issues and Management in Coastal Areas

Illegal Activities: Destructive fishing methods (blast fishing, use of poisons), intrusion into municipal waters, and habitat destruction threaten marine ecosystems.
Conservation Measures: Effective coastal management must address linked issues impacting the fishing industry and marine biodiversity.
CITES: The Convention on International Trade in Endangered Species of Wild Fauna and Flora aims to regulate trade of threatened species globally.

Fisheries and Sustainability

Fisheries face declining productivity with low economic returns due to multiple factors, including pollution and habitat loss.
Illegal practices, such as cyanide fishing, severely disrupt coral ecosystems, resulting in significant socio-economic losses, much higher than immediate gains from such practices.

Licensing and Registration of Fisherfolk

Local governments maintain registries to monitor municipal fisherfolk and fishing activities, ensuring fair resource usage and compliance with regulations.
National Registration Program: Supports a systematic application for the registration of municipal fishing vessels and gears, enhancing fisheries management.
