Tools and Equipment in Fisheries

• These are used for recirculation purposes. They are horizontal & vertical centrifugal pumps.

  Water Pump
• The monitoring of water temperature, ensuring optimal conditions for aquatic organisms.

  Laboratory Thermometer
• Used to measure salinity accurately and efficiently.

  Salinometer
• It measures and monitors potential hydrogen (pH) accurately.

  pH Meter
• Fish cannot survive water below pH 4 and above pH 11 for a long period. Fish can survive pH levels between 6.5 and 9.
• If the water did not meet the required pH level, the fish will grow poorly and affect reproduction.
• This measures the amount of free oxygen gas present in water.

  Dissolved Oxygen Meter
• This monitors water quality in lakes, rivers, and coastal areas.

  Secchi Disk
• A tool used for collecting aquatic organisms.

  Scoop Net
• A tool that is versatile in catching, valuable assets in both commercial and recreational fishing activities.

  Seine Net
• It is thrown or cast by hand. It consists of a circular net with weights and a series of brails.

  Cast Net
• Used to gather or harvest from the substrate or water columns.

  Hand Diggers and Collectors
• Mechanical devices used to remove sediment, debris, or unwanted materials.

  Dredges
• A tool used to catch fish by piercing or impaling them.

  Spears
• Substances used to stun or immobilize fish temporarily.

  Stupefying Aids
• Also called "angling gear" are traditional and widely used tools in catching fish.

  Hooks and Lines
• Traditional Fishing Bait Methods

  - Hand Line Fishing

  - Spearfishing

  - Cast Netting
• Modern Fishing Bait Methods

  - Rod and Reel Fishing

  - Trolling
• A traditional bait method where anglers use a single line with bait or lured, often practiced in shore or small boats.

  Hand Line Fishing
• A traditional bait method that uses a spear or trident to catch fish in their natural habitat.

  Spearfishing
• A traditional bait method that is prevalent in many coastal regions, where a weighted net is thrown to capture schools of fish.

  Cast Netting
• A modern bait method that has precision casting and better control over the fight with fish.

  Rod and Reel Fishing
• A modern bait method that involves trailing lures or baited lines behind a moving boat to cover a larger area and target active fish.
