Study Notes
Fish Farming
- Fish farming is a branch of agriculture involving breeding, rearing, and marketing of fish.
- In Guyana and the Caribbean, fish farming is primarily for food, as fish is a nutritious and relatively cheap source of protein.
Nutrition and Products
- Fish provides a valuable protein that is easily digested and rich in oil, vitamins A and D, and minerals like iodine, phosphorous, and calcium.
- Other products obtained from fish include fertilizers, glue, soap, linoleum, shortening, paint, lubricant, ink, gelatin, artificial pearls, sharkskin, leather, and insulin.
Types of Fish
- Fish can be classified into several groups, including:
- Freshwater or inland fish (e.g., patwa, houri, hassar, tilapia)
- Saltwater or sea water fish (e.g., catfish, snapper, shark, snook)
- Scale fish (e.g., patwa)
- Unscale fish (e.g., gail backer)
- Deep-sea fish (e.g., snapper, grouper)
- Offshore fish (e.g., puce, mullet)
Fishing Methods
- There are three main methods of fishing:
- Inland fishing (freshwater fishing)
- Inshore or coastal fishing
- Deep-sea fishing or offshore fishing
Inland Fishing
- Inland fishing is done in ponds, swamps, lakes, creeks, and rivers.
- Methods used include:
- Poisoning fish
- Shooting with bow and arrow
- Trapping by allowing the water to channel out
- Casting nets
- Hook and line
- Feeling by hand in shallow water
- Trapping seine
Inshore or Coastal Fishing
- Inshore fishing is done in coastal waters or along the shores in small open boats.
- Methods used include:
- Casting nets along the shore
- Throwing out baited hooks from small boats
- Using the pin seine method to trap fish
- Catching fish such as queriman, mullet, snook, gail-barker, butter-fish, shark, morocut, catfish, and highwater curass
Deep-Sea Fishing or Offshore Fishing
- Deep-sea fishing is done by trawling fish pots, nets, heavy lines, or trawl-nets.
- Fish caught by trawling include snappers, bangamary, trout, tuna, mackerel, and shrimps.
- Trawlers are equipped with sophisticated equipment to detect large shoals of fish under the sea.
Aquaculture
- Aquaculture is the rearing of fish in artificially constructed ponds.
- The most popular fish reared under artificial conditions is the Tilapia (Tilapia mossambica).
- The hassar has also become popular in recent times.
Rearing Tilapia
- Tilapia mossambica grows in fresh to brackish water.
- Males are longer than females and have pointed vents.
- Males attain a weight of 56 grams in 3 months and 168 grams in 6 months.
- Females deposit eggs in holes made in the pond and incubate them.
Setting Up a Pond
- The pond site should be located near an adequate source of water and have soil that can hold water all year round.
- The pond should be constructed with:
- A minimum size of one-tenth of an acre
- A rectangular shape
- A depth of 4.5' to hold a minimum of 3.4' of water
- Sides sloping at a 30° angle
- The bottom graded to allow complete drainage
- Grass or suckers planted along the dam to minimize erosion
Flooding and Fertilizing the Pond
- The pond is flooded to a depth of 3.0' and fertilized with organic or inorganic fertilizers or both.
- The acidity of the water should be checked and should be between 6.5-9.0 pH.
- 2 tons of limestone per acre should be applied to reduce acidity.
- Fertilizers are applied at the rate of 2,000 Ibs/ac of organic manure initially and then 500 lbs/ac weekly.
Stocking and Feeding
- The pond should be stocked with only one sex of tilapia, and that is the male.
- The pond should be stocked at the rate of 6,000 or 25Olbs of fingerlings/ac if supplementary feeding will be done.
- Fish should be introduced two weeks after initial fertilizing.
- Fish should be fed 59% of their body weight daily.
- The most popular feedstuff is the poultry growing ration.
- Feeding should be done at least twice daily.
Fish Farming and Fish Culture
- Fish farming involves breeding, rearing, and marketing of fish for food, providing a nutritious and affordable source of protein.
- Fish is a valuable source of protein, easily digested, and rich in vitamins A and D, iodine, phosphorus, and calcium.
Fish Products and By-Products
- Fish products include fertilizers, glue, soap, linoleum, shortening, paint, lubricant, ink, gelatin, artificial pearls, sharkskin, leather, insulin, and other medicines.
Fish Characteristics
- Fish are cold-blooded vertebrates that live in salt or fresh water, with some covered in scales.
- They breathe using gills and move using fins.
- Fish can be herbivores (plant-eaters), carnivores (meat-eaters), or omnivores (both plant and animal eaters).
- Some fish lay eggs, while others are viviparous (give birth to live young).
Classification of Fish
- Freshwater fish: e.g., patwa, houri, hassar, tilapia
- Saltwater fish: e.g., catfish, snapper, shark, snook
- Scale fish: e.g., patwa
- Unscaled fish: e.g., gail backer
- Deep-sea fish: e.g., snapper, grouper
- Offshore fish: e.g., puce, mullet
Fishing Methods
- Inland fishing (freshwater fishing): done in ponds, swamps, lakes, creeks, and rivers using methods like poisoning, shooting, trapping, casting nets, hook and line, and feeling by hand.
Inshore or Coastal Fishing
- Done in coastal waters or along shores in small open boats using methods like casting nets and throwing baited hooks with corks or calabash.
