This Ihas considerable economic, ecological and developmental impacts (see Impacts of bycatch right). In some cases, bycatch reduction is already technically feasible and economically advantageous (Valdemarsen & Suuronen ) – what is needed now is the political will to implement and enforce solutions.

  • Gill Nets and Their Operation
    Gill Nets and their Operation Saly N. Thomas Central Institute of Fisheries Technology P.O. Matsyapuri, Cochin – 682 029 Email: [email protected] Gill net is a highly selective and passive gear accounting for 20% of all the fishing methods of the world. The simplicity of its design, construction, operation and its low energy requirement make the gear very popular in all the sectors especially in the traditional sector. It is a highly selective gear and the use of this gear in a responsible way ensures resource conservation. The gear is a vertical wall of netting, which is kept erect in water by means of floats and sinkers. The gear is mostly rectangular in shape whose upper end is mounted to a float line (head rope) and the lower end to a sinker line (foot rope). The nets are operated in the surface, column or bottom layers of the water column in inland, coastal and deep sea. Gill nets are operated for the capture of different groups of fishes such as sardine, mackerel, prawn, hilsa, and larger varieties like tuna, shark, seer fish, and other large pelagics. When operated for such larger varieties in the deeper areas of the sea the nets extend to several kilometers. Mechanism of fish capture in gill nets The fact that separates gill nets from all other type of fishing is that in gill nets the `mesh’ of the net serves the dual function of `selecting’ the fish to be caught and catching it. The capture of fish in gill nets depends on the net construction, its dimensions, and the shape of the fish body.

  • Ghost Net Impacts on Coral Reefs Time to Complete Lesson: 20-30 Minutes
    Ghost (net) Busters Ghost Net Impacts on Coral Reefs Time to complete lesson: 20-30 minutes Purpose of module: This module allows students to simulate the impacts of ghost nets on a coral reef. Students will build a model healthy reef ecosystem, damage it using a ghost net, and then remove it from the reef. Students will conduct a damage assessment caused by the net dragging across the reef using quadrats. Background information: Coral reefs, also known as the rainforests of the sea, are one of the most diverse and ecologically complex marine ecosystems. They are found in warm, tropical waters with high salinity and high light exposure. A coral reef is made up of individual coral polyps that resemble tiny anemones and are attached to the reef. Each coral polyp is less than half an inch in diameter, but they live in colonies which Figure 1: A healthy coral reef system. can expand and take up the size of a small car. Reef building corals have a skeleton made of calcium carbonate, a mineral that is left behind when an individual coral dies. Another coral may settle on that spot and grow on top of the remaining skeleton. This allows a coral reef to grow a few centimeters each year, eventually reaching massive sizes. Coral reefs provide food and shelter for many plants, invertebrates, and fish. It is estimated that at least 25% of all marine life spendCredit: part MostBeautifulThings.net of their life at a coral reef. Coral reefs provide shelter for small fish, and small fish attract larger fish, which in turn attract large predators like sharks.

  • Design a Safe Fishing Net Notes for Teachers
    You need: Design a safe • Paper or card • Pencils • Colouring pens fishing net or pencils Thousands of whales and dolphins die every year because they get trapped in fishing nets. They can’t get to the surface to breathe, so they suffocate and drown. How can we design nets that can catch fish, but won’t accidentally catch whales and dolphins? Each child will need some 1 paper, a pencil and some colouring supplies. Their challenge is to design a net that will successfully catch fish, but won’t catch whales and dolphins. Encourage children to think about what they’ve learnt about whales 2 and dolphins that might help them with their designs, for example: • How do dolphins find their food? • How big are whales and dolphins? Scan or take photos of the best net designs and send them to [email protected] – we’d love to see them! Design a safe fishing net Notes for teachers Ask the children questions to encourage them to think about their designs. Their solutions might involve stopping whales and dolphins from swimming into the net in the first place, or ways to escape if they do get trapped. Some great ideas from other children have included: • Brightly coloured nets that are easily seen; • Nets that make noise to scare whales and dolphins away; • Sensors that detect if a whale or dolphin is nearby, then retract the net; • Monitored cameras so fishermen can see and release a trapped whale or dolphin; • Nets that do not close if a whale or dolphin, or the weight of a whale or dolphin, is detected.

These collisions occurred mostly at night or in fog conditions where visibility was restricted and additional lookouts were not engaged. Discussion The Chinese port Port of Ningbo-Zhoushan is located in Ningbo and Zhoushan on the coast of the East China Sea, in Zhejiang province and is ranked the busiest cargo port in the world. Large fleets of fishing junks may be encountered on the coast of China. The junks may not be carrying lights. They are solidly built and serious damage could be incurred by colliding with them. Fishing vessels vary from traditional rowing or sailing craft as little as 3m long to modern trawlers 15m long and over. We recently met with China Maritime Safety Administration (MSA) to review the collision cases and explore possible measures to help prevent similar casualties and loss of life. Attached is an Advisory prepared by Ningbo MSA that provides guidance for Master’s on navigating through the East China Sea and areas where there may be high concentrations of fishing vessels.

  • Addendum Iii to Amendment 4 to the Interstate Fishery Management Plan for Weakfish
    Atlantic States Marine Fisheries Commission ASMFC Vision Statement: Healthy, self-sustaining populations for all Atlantic coast fish species or successful restoration well in progress by the year 2015 ADDENDUM III TO AMENDMENT 4 TO THE INTERSTATE FISHERY MANAGEMENT PLAN FOR WEAKFISH Board Approved May 8, 2007 Acknowledgements This addendum was prepared by the Commission’s Weakfish Plan Development Team. Development of the document benefited greatly from the input of the Weakfish Technical Committee and members of the Weakfish Management Board. The Weakfish Management Board approved Addendum III on May 8, 2007. 2 STATEMENT OF THE PROBLEM As a result of Shrimp Amendment 6, the Atlantic States Marine Fisheries Commission’s Weakfish Amendment 4 and the South Atlantic Fishery Management Council’s Shrimp Fishery Management Plan are inconsistent with regard to the amount and type of bycatch required of certified bycatch reduction devices (BRDs). Without modification to Weakfish Amendment 4, new BRDs certified for use in federal waters would not be certified for use in state waters. The Commission is committed to close cooperation with the Council and the Weakfish Management Board is required to ensure that state and federal fishery management programs are coordinated, consistent, and complementary (ASMFC 1995). The Commission supports the basis of the Council’s decision to modify the BRD certification requirements in Amendment 6. However, the reasoning included a statement on weakfish status based on earlier virtual population analysis that has since been proven to be flawed and the weakfish stock is currently below the biomass threshold (ASMFC Weakfish Stock Assessment Subcommittee 2006a, 2006b). While it is not clear whether the Council would have made the same decision with a declining weakfish stock, the Weakfish Management Board clarified that modification of the requirement in Weakfish Amendment 4 is the preferred option for the following reasons.
