Traditional fishing Craft of India by Ashish sahuAshish sahu
Fishing crafts are most essential for catching the fish in large scale in water bodies. A large variety of crafts (boats) have been designed for marine and inland fishing in India. The types of fishing crafts of India falls under two general categories. These are Non –mechanized and mechanized fishing crafts.
Based on the topographical variations and difference in habits and habitats of fishing, different types of crafts and gears are used in various inland water system of India. The simplest and most primitive types of craft used for fishing in inland water are the rafts and songas, operated in calm water. In the larger rivers and estuaries subject to strong current and tidal movement, sturdier plank boats are used.

Gear selectivity refers to a fishing gear's ability to target and capture certain species, sizes, or sexes of fish while allowing incidental bycatch to escape unharmed. Most gears like trawls selectively catch larger fish, while some gears like gill nets selectively catch fish within a certain size range. The selection curve shows the size ranges caught by a gear. A bell curve indicates the optimum size range, while a sigmoid curve shows how percentage retained increases with size. Gill nets catch fish by wedging, gilling, or tangling in meshes. Mesh size, net dimensions, hanging ratio, and environmental factors influence gill net selectivity. Proper understanding of selectivity allows sustainable fisheries that return juveniles.
This document discusses fish seed certification and quarantine procedures. It covers topics like quality assurance of fish seeds, certification processes in different countries, guidelines for good aquaculture practices, and general principles and considerations for quarantine facilities. Quarantine involves isolating aquatic animals to observe for diseases and involves proper treatment, testing, and containment to prevent spread of pathogens.
Gill nets are widely used passive fishing nets that capture fish via their gills. They can be operated in various ways - set vertically in the water column, drifting in currents, or encircling an area. Gill nets are selective for certain species depending on mesh size and can be used to catch fish living in surface waters, midwaters, or along the bottom. While gill nets are effective at harvesting target species, they also result in accidental bycatch of non-target animals and can continue to capture fish if lost or abandoned, known as ghost fishing.
Fishing is the art of catching fish and other aquatic animals. Many years ago man started using various type of gear used for hunting the terrestrial animals and for fishing also. It is very difficult to say which started first, but some time it is opined that fishing is younger. Reason behind it is easy to catch animals in the land than in the water. In olden days fishing was not having much importance as there was no demand for fish. Earlier fishing was restricted to a particular community but it is not so now. In order to meet the increased demand, fishing is now carried out industrially. Fishing technology not only concerns fishing gear, fishing methods and vessels but also concern Biological and Environmental factors
The document provides an overview of the Code of Conduct for Responsible Fisheries (CCRF) presented by Karthikachandran from the University of Kerala. The CCRF was adopted by FAO in 1995 and provides principles and standards for sustainable fisheries. It covers conservation, management, and development of fisheries. The summary includes the origins, goals, actors involved in implementing the CCRF, its structure with 12 articles addressing issues like fisheries management, fishing operations, aquaculture, and research.

This document discusses culture techniques for groupers, including important species, distribution, biology, habitat, nursery rearing, and grow-out. It describes experiments conducted to develop grouper broodstock in sea cages off Visakhapatnam, India. Broodfish were stocked and grown in cages and tanks, achieving higher survival and maturity in cages. Induced spawning trials were conducted, leading to the conclusion that sea cages are better than tanks for broodstock development and domestication of greasy groupers. This represents progress toward commercial grouper seed production and farming in India.
The document discusses various terms and concepts related to fishing vessels and boats. It provides definitions for types of vessels, classifications of boats, parts of boats, and measurements used to describe boats such as length, tonnage, and capacity. Key facts include that in 2012 there were over 4.7 million fishing vessels globally, with 57% being engine-powered, and about 79% of motorized vessels being under 12 meters in length.
Factors considered for designing or selection fishing gear, Joselin J
The document discusses factors to consider when designing or selecting fishing gear. It states that the choice of fishing gear depends primarily on the biological, behavioral, and distribution characteristics of the target species. The gear must be selected based on attributes suitable for the specific fishing conditions and resources. Some key factors discussed are the biology, behavior, distribution, fishing depth, currents, visibility, sea bottom conditions, and other practical considerations. No single gear is suitable for all conditions, and trade-offs may be necessary.
A fish aggregating device is a man-made object used to attract ocean going pelagic fish such as marlin, tuna and mahi-mahi. They usually consist of buoys or floats tethered to the ocean floor with concrete blocks. FADs attract fish for numerous reasons that vary by species.
Fisheries aggregating devices (FADs) are human-made structures anchored offshore that attract fish, making them easier to catch so you can have a great fishing experience.
India has a long coastline and large exclusive economic zone with significant marine fisheries potential. Fisheries management responsibilities are shared between central and state governments. The central government ministries of agriculture, commerce, environment and defense play roles, while states have jurisdiction over territorial waters. Management measures include gear restrictions, closed seasons and areas. Overfishing from lack of controls threatens stocks, highlighting the need for sustainable fisheries management.
Pelagic fish inhabit ocean waters near the surface or in middle depths. They often form large shoals and undertake vertical or horizontal migrations. Their aggregating behaviors increase their catchability by fisheries. Pelagic fish range in size from small forage fish like herring and sardines to large apex predators such as bluefin tuna and sharks. They tend to be streamlined swimmers capable of long distance migration.
Satellite remote sensing is beginning to play an important role in locating potential fishing zones and managing fishery resources by measuring ocean parameters like sea temperature and color from space. Changes in ocean conditions influence fish stocks, so remote sensing provides information on ocean variations and their effects on fish distribution. In India, satellite data on sea surface temperature and chlorophyll are used by INCOIS to create maps of potential fishing zones distributed weekly to fishermen. Remote sensing allows fishermen to reduce scouting time and fuel use locating fishing zones, and provides data for fishery management decisions and assessing fish stocks.
Recirculating aquaculture systems (RAS) operate by filtering water from the fish (or shellfish) tanks so it can be reused within the tank. This dramatically reduces the amount of water and space required to intensively produce seafood products.
This document describes different types of aquaculture practices based on salinity levels: mariculture for saltwater environments, metahaline culture for supersaline areas, brackishwater culture, and freshwater culture. For each environment, various culture methods are outlined, such as cage culture, raft culture, rack culture, and integrated fish farming. Culture techniques like monosex culture and air-breathing fish culture are also summarized.
The document discusses India's fisheries management. It notes that India has vast inland and marine fisheries resources that provide food and employment. Management is undertaken by both central and state governments and includes regulations on gear, seasons and habitat protection. Five-Year Plans have aimed to increase production sustainably. Community-based and co-management initiatives also play a role in governance. Key challenges include sustainably utilizing resources and balancing conservation and livelihoods.
10. Impacts of climate change on aquaculture and fisheries in the Mekong regionLittle Daisy
This document outlines a proposed project to address climate change adaptation needs in aquaculture and inland fisheries in the Mekong Delta region of Vietnam. The project would have 4 main components: 1) conducting vulnerability assessments and risk mapping, 2) developing and piloting adaptation measures using an ecosystem approach, 3) building adaptive capacity, and 4) monitoring and evaluation. The overall objective is to strengthen resilience and adaptive capacity of rural communities dependent on aquaculture and fisheries in the face of climate change risks. Key activities would include research, developing management plans, strengthening government and community capacity, and mainstreaming adaptation into policies. The project aims to support sustainable development and food security in vulnerable communities.
The document discusses the Code of Conduct for Responsible Fisheries (CCRF) established by the Food and Agriculture Organization (FAO) of the United Nations. It originated from calls at FAO meetings in the early 1990s for more responsible fishing practices and management. The CCRF was finalized after international consultations from 1992-1995. It sets out voluntary principles and international standards for sustainable fishing. The CCRF aims to ensure effective conservation, management and development of living aquatic resources while also recognizing the nutritional, economic and cultural importance of fisheries.
Impacts of IUU fishing in the Asia-Pacific regionfishersforum
The document summarizes a study on initiatives to address illegal, unreported, and unregulated (IUU) fishing globally and in the Asia-Pacific region. The study involved questionnaires to 21 Asia-Pacific Economic Cooperation member countries and 48 other countries bordering the Pacific Ocean. It found that IUU fishing is a major problem in the region, possibly accounting for up to 16% of total catch worth $5 billion annually. Drivers of IUU fishing included ineffective management, excess fishing capacity, disputed boundaries, and lack of alternative livelihoods. Responses by countries have included regional plans of action, increased monitoring and enforcement, and alternative employment programs.
The document discusses three acts related to management of Indian fisheries:
1) The Maritime Zone of India (Regulation of Fishing by Foreign Vessels) Act, 1981 regulates fishing by foreign vessels in India's territorial waters and exclusive economic zone. It requires foreign vessels to obtain licenses or permits to fish.
2) The Merchant Shipping Act, 1958 establishes a National Shipping Board and regulates registration of Indian ships. It provides for regulation of shipping and development of India's merchant marine.
3) The Marine Products Export Development Authority Act, 1972 establishes an authority to promote and develop India's marine products industry and regulate export of marine products. It registers fishing vessels, processing plants, exporters and collects related
This document defines and describes various terms related to bycatch in fisheries including accidental catch, incidental catch, non-target species, byproduct, undersized, catch, release, bycatch, bycatch reduction devices, turtle excluder devices, square-mesh codends, fisheyes, and other modifications that can help reduce bycatch in trawling operations. Examples and explanations are provided for each term.
The document provides information about the mud crab (Scylla serrata), including its classification, distribution, ecology, and methods for farming and hatchery management. It notes that mud crabs are found naturally in the Indo-Pacific region and are an economically important species. Mud crab farming can be done using grow-out systems, where young crabs are raised for 5-6 months until market size, or fattening systems, where soft-shelled crabs are raised for a shorter period. Hatchery management involves broodstock selection and care, spawning and larval rearing techniques, and achieving survival rates as high as 18.1% compared to the world average of 3-3.5
Marine fisheries act – west coast of india Joselin J
The Marine Fishing Regulation Acts regulate fishing along India's west coast through measures like restricting mesh sizes, establishing minimum and maximum fish sizes, regulating fishing gear, reserving zones for traditional fishermen, and declaring closed seasons. These Acts demarcate fishing zones for non-mechanized and mechanized vessels, with distances from shore varying by state. In general, areas within 5-10 km are reserved for non-mechanized vessels. Various west coast states have enacted these Acts between 1980-2003, with some variations in the specified fishing areas and seasons closed for each state. Zonation and other fishing regulations in states along the west coast establish restrictions on fishing gear, vessel types allowed in certain areas, and mesh size minimums
Case examples of IUU fishing in the Asian region – links to Port State MeasuresSimon Funge-Smith
The document summarizes a study on illegal, unregulated, and unreported (IUU) fishing by foreign vessels in Asia. It identifies 33 hotspots of IUU fishing across the region. The major hotspots account for 82-85% of the total estimated IUU catch of 2.06-2.51 million tonnes worth $3.65-5.24 billion. The hotspots involve issues like lack of authorization, boundary violations, misreporting of catches, and involve a mix of trawling and purse seine fishing. Addressing IUU fishing requires strengthening monitoring, control and surveillance (MCS), port controls, regional cooperation, and improving domestic fisheries management and governance.
