Capture fishery-the fish is catch from natural water, both marine and inland .modern technology is used for capture and storage before marketing. electronic equipment is used to locate fish in the sea. mechanised fishing boats and deep sea trawlers are often employed in capture fishery.
culture fishery -it is cultivating, rearing and harvesting of fish. culture fishery is also called fish farming or pisciculture . the growing of various type of aquatic organism in water bodies is called aquaculture

Capture Fisheries:
Capture fisheries refer to the harvesting of fish and other aquatic organisms from their natural habitats such as oceans, seas, rivers, and lakes. It involves catching fish using various techniques such as nets, hooks, traps, and dredges. This form of fishing is carried out by both commercial and recreational fishermen, targeting a wide range of species for various purposes including food, bait, or sport.

Characteristics of Capture Fisheries:
1. Wild Fish Stocks: Capture fisheries rely on the natural populations of fish and other aquatic organisms present in their habitats. These stocks are influenced by environmental factors, such as temperature, water quality, and availability of food, which can affect the abundance and distribution of fish.

2. Variability: The abundance and availability of fish in capture fisheries can vary significantly over time and location. This variability is influenced by factors such as natural fluctuations in fish populations, climate change, and fishing pressure.

3. Sustainable Management: Due to the potential for overfishing and depletion of fish stocks, sustainable management practices are essential in capture fisheries. This includes setting fishing quotas, implementing size and gear restrictions, and establishing protected areas to allow stocks to replenish.

Culture Fisheries:
Culture fisheries, also known as aquaculture or fish farming, involve the cultivation of fish and other aquatic organisms in controlled environments such as ponds, tanks, or cages. It is a process of rearing fish from the larval stage to market size under controlled conditions, providing food and optimal conditions for growth.

Characteristics of Culture Fisheries:
1. Controlled Environment: Culture fisheries take place in controlled environments where water quality, temperature, and feeding can be regulated. This enables farmers to optimize conditions for fish growth, reproduction, and disease prevention.

2. Intensive Production: Fish farming allows for high stocking densities, enabling efficient use of space and resources. This intensive production can result in higher yields compared to capture fisheries.

3. Species Selection: In culture fisheries, specific fish species are selected based on their commercial value, growth rate, market demand, and adaptability to the farming environment. Commonly farmed species include tilapia, salmon, carp, and catfish.

4. Disease Management: Due to the higher stocking densities and confined environments, disease management is crucial in culture fisheries. Measures such as regular monitoring, vaccination, and biosecurity protocols are implemented to prevent and control disease outbreaks.

Differences between Capture Fisheries and Culture Fisheries:
1. Source: Capture fisheries rely on wild fish stocks, whereas culture fisheries involve the farming of fish in controlled environments.

2. Control: Capture fisheries are subject to natural variability and external factors, while culture fisheries provide controlled conditions for fish growth and production.

3. Sustainability: Capture fisheries require sustainable management practices to prevent overfishing, whereas culture fisheries can be designed to minimize impacts on wild fish populations.

4. Production: Capture fisheries depend on the availability and abundance of wild fish populations, while culture fisheries have the potential for higher and more consistent production through intensive farming practices.

5. Species Selection: Capture fisheries target a wide range of species based on their natural distribution, while culture fisheries selectively breed and raise specific species for market demand.

In summary, capture fisheries involve the harvesting of fish from natural habitats, while culture fisheries focus on the controlled cultivation of fish in artificial environments. Both play important roles in meeting the global demand for seafood, but their methods, characteristics, and management approaches differ
