Study Notes
Principles of Aquaculture (FISH 333, Lecture 1.1)
- Aquaculture is the farming of aquatic organisms, including fish, molluscs, crustaceans, and aquatic plants.
- Farming involves intervention in the rearing process to enhance production, such as stocking, feeding, and predator protection.
- Individual or corporate ownership of the farmed stock is also a key component.
Importance of Aquaculture
- A quote from an ancient Chinese proverb highlights the enduring value: "Give a man a fish and you feed him for a day; teach the man how to grow that fish, and you feed him for life."
- Aquaculture is crucial for food security and foreign exchange.
- It contributes to income generation and poverty reduction.
- Aquaculture enhances natural fish stocks.
- It provides opportunities for sports, recreation, and ornamental fish.
- Aquaculture produces bait as well as industrial and pharmaceutical products.
Challenges to Aquaculture in Ghana
- Disease incidence is a significant concern.
- Quality and availability of fish seed (young fish/fry for stocking) are problems.
- The quality and affordability of fish feed are also challenges.
- Access to capital is a hurdle for many farmers.
- Land tenure systems can complicate operations.
- Permit acquisition processes can be bureaucratic.
- Marketing fish effectively presents challenges.
- A lack of insurance coverage is a downside.
- Capacity building for aquaculture professionals is needed.
Classification of Aquaculture Management Levels
- Extensive
- Semi-intensive
- Intensive
Types of Production Systems
- Land-based holding systems
- Water-based holding systems
Types of Culture Systems
- Land-Based:
- Earthen ponds
- Concrete ponds
- Concrete tanks
- Plastic tanks
- Water-Based:
- Fish cages
- Fish pens
Phases of Aquaculture
- A cyclical process from hatchery production to grow-out, broodstock management, and harvest/market.
Site Selection Factors
- Ecological factors (land, water, weather, vegetation, soil).
- Biological factors (species, stocking materials, other organisms).
- Operational factors (scale of operation, culture system, security).
- Socio-economic factors (land ownership, land/water use, proximity to market, roads).
Species Selection Factors
- Biology of the species (growth, reproduction, diet).
- Culture technology (technical procedures, nutrition).
- Production efficiency (growth rate, FCR, hardiness).
- Economic and market value (demand, price).
- Impact of species on the environment (escapement, waste).
Water as a Fish Habitat
- Water availability, accessibility, quantity, and quality are fundamental to fish farming success.
Sources of Water for Aquaculture
- Springs
- Wells
- Rivers/streams/lakes
- Surface runoff
- Groundwater
- Municipal/pipe-borne water
