1. 1. Aquaculture (Fish Farming)

      • Aquaculture involves the controlled cultivation of fish and other aquatic organisms in freshwater, brackish, or marine environments. It focuses on breeding, raising, and harvesting aquatic species to meet food demands and reduce pressure on wild fish stocks. This branch is essential for global food security and sustainable seafood production (FAO, 2020).

   2. Capture Fisheries (Fishing) 

      • Capture fisheries refer to harvesting fish from natural water bodies such as oceans, rivers, and lakes using various fishing gear like nets, hooks, and traps. This branch is vital for providing wild-caught fish for human consumption and economic activities (Jennings et al., 2001).

   3.  Fisheries Ecology

      •  Focuses on the biological processes affecting fish and invertebrate populations, including life history theory, predator-prey relationships, bioenergetics, and trophic ecology.  
        Fisheries ecology is sometimes referred to as Aquatic Ecology, which studies the interactions between aquatic organisms and their environments to understand ecosystem health (Odum & Barrett, 2005).

   4.  Fisheries Technology

      • This branch focuses on the development and application of technologies for fishing and aquaculture.
      • It includes research on fishing gear, vessel design, and aquaculture systems.
      • Key aspects include:
        • Fishing gear development
        • Acoustic fish detection
        • Aquaculture engineering
        • Post-harvest technology

   5. Fisheries Socioeconomics

      • This area examines the economic and social aspects of fisheries.
      • It explores the role of fisheries in providing livelihoods, food security, and cultural values.
      • Key aspects include:
        • Fisheries economics
        • Social impacts of fisheries
        • Community-based fisheries management.

   6. Fish Preservation

      • This branch focuses on techniques to prevent spoilage of fish and aquatic products. Methods include salting, smoking, drying, freezing, and refrigeration. Preservation ensures the quality and safety of seafood during storage and transportation (Huss, 1995).

   7. Fish Processing

      • Fish processing involves converting raw fish into consumable or value-added products through methods like filleting, canning, freezing, and packaging. This branch enhances the marketability and shelf life of fish products (Hall, 1997).

   8. Fishmongering

      • Fishmongering deals with the trade and retailing of fish products. It plays a critical role in connecting producers to consumers by ensuring the availability of fresh or processed seafood in markets (FAO, 2020).

   9. Fisheries Management

      • Fisheries management focuses on sustainable practices to maintain healthy fish stocks and ecosystems. It involves developing policies based on scientific research to regulate fishing activities and prevent overexploitation (Hilborn & Walters, 1992).

• Population Dynamics: This area examines changes in fish populations over time due to factors like fishing pressure, environmental conditions, and reproduction rates (Quinn & Deriso, 1999).

• Fisheries Economics: This branch analyzes the economic aspects of fisheries, including resource allocation, market dynamics, and cost-benefit analyses (Gordon, 1954).

• Fisheries Genetics: This field investigates genetic diversity within fish populations to inform conservation efforts and selective breeding programs (Carvalho & Hauser, 1994).

• Fisheries Biology/Ichthyology: Focuses on the physiology, behaviour, taxonomy, and life history of fish species. Essential for understanding reproduction, growth, and habitat requirements.

• Fisheries Technology: Studies the design of fishing gear, aquaculture systems, and monitoring tools (e.g., GPS, drones) to improve efficiency and reduce environmental impact.

• Fisheries Conservation Biology: Protects endangered species, restores habitats, and mitigates threats like pollution and overfishing.

• Fisheries Policy: Formulates laws and international agreements (e.g., UNCLOS) to regulate fishing practices and ensure compliance.

• Quantitative Fisheries Science: Applies statistics, bioinformatics, and modelling to analyse data and predict trends.

1. 1. Climate Change: Fish species exhibit varied responses to climate change, which can significantly alter their physiology and behaviour. The impacts of global warming on fish distribution, phenology, and size are critical areas of concern (Davis et al., 2024).

   2. Hypoxia and Ocean Acidification: These environmental stressors can decrease the performance of ectothermic species, making them more vulnerable to predation and affecting their survival rates (Davis et al., 2024).

   3. Pollution and Habitat Degradation: Pollution can severely damage aquatic habitats, leading to toxic effects on fish populations and contributing to declines in biodiversity (FAO, 2008).

1. 1. Overfishing: Despite increased management efforts, overfishing remains a significant issue that threatens both biodiversity and ecosystem functioning. Unsustainable fishing practices continue to deplete fish stocks faster than they can replenish (FAO, 2008). Many fish stocks globally are overfished or depleted, reducing biodiversity, ecosystem imbalance, and economic hardship for fishing communities. Many fish stocks globally are overfished or depleted, leading to reduced biodiversity, ecosystem imbalance, and economic hardship for fishing communities (FAO, 2022). According to the FAO's "The State of World Fisheries and Aquaculture 2022" report, the proportion of fish stocks within biologically sustainable levels has decreased to 64.6% in 2019.  This overfishing arises from the following

      • Unregulated/Poorly Regulated Fishing: Lack of effective enforcement, illegal fishing practices, and inadequate monitoring contribute significantly. The Sea Around Us project highlights that IUU (Illegal, Unreported, and Unregulated) fishing is a major driver of overexploitation (Pauly & Zeller, 2016).

      • Excessive Fishing Capacity: Too many vessels chasing too few fish is a widespread problem. As highlighted in the "Advances in Marine Biology," overcapacity remains a crucial factor causing the depletion of stocks globally (Beddington et al., 2007).

      • Harmful Subsidies: Government subsidies can incentivize overfishing by artificially lowering operating costs for fishing fleets. A study by Sumaila et al. (2016) in Science Advances quantified the detrimental impacts of harmful fisheries subsidies on global fish stocks.

      • Data Deficiencies: Lack of accurate and timely data on fish stocks makes it difficult to set sustainable catch limits.

   2. Genetic Structure: A lack of understanding regarding the genetic structures within exploited fish species has resulted in ineffective management policies. It is essential to comprehend the genetic diversity and breeding patterns of fish populations to develop appropriate conservation strategies (Davis et al., 2024).

   3. Sustainable Fisheries: Many fisheries worldwide struggle with sustainability issues, including overcapacity and inadequate management frameworks that do not account for current population structures (ICES, 2003).

1. 1. New Technologies: The rapid development of advanced scientific techniques offers new tools for fisheries scientists but also presents challenges in integrating these technologies into existing management practices (ICES, 2003).

   2. Genomics: Genomic research provides insights into fish demographics and population structures but requires significant investment in infrastructure and expertise (Davis et al., 2024).

   3. Environmental DNA (eDNA): The use of eDNA for monitoring fish populations is promising but still faces challenges related to standardization and interpretation of results (Davis et al., 2024).

1. 1. Species Knowledge: There are substantial knowledge gaps regarding the movements and migrations of many commercially important fish species, which complicates effective management (FAO, 2008).

   2. Deep-Sea Ecosystems: Deep-sea ecosystems remain poorly understood, highlighting the need for urgent research as these areas face increasing threats from fishing and mining activities (Davis et al., 2024).

   3. Energy Use Patterns: Understanding energy use patterns in wild fish populations is crucial for assessing the impacts of environmental changes on their survival (Davis et al., 2024).

Addressing these challenges requires collaborative efforts among scientists, managers, and stakeholders to integrate research findings into effective fisheries management practices.
