  2. Catch Target species Valuable bycatch Non-valuable bycatch, over quota species and undersized individuals Market Discarded

  3. Fishing gear doesn't just capture the target fish species. Millions of baby fish and fish with no commercial value are also being accidentally caught ... and then discarded, usually dead, back into the ocean - along with dolphins, marine turtles, seabirds, sharks, corals, starfish, and many other marine species. This incidental capture of so-called "non-target species" is called bycatch, and occurs wherever there is fishing. Sometimes bycatch may be kept or sold (incidental catch); other times, bycatch cannot be used — for example, if it is undersized or a protected species — and must be thrown back. This returned bycatch is called discard. Bycatch is a major fisheries management problem, wasting time and hundreds of millions of dollars in damaged gear and inefficient fishing methods. It’s also causing dramatic declines in populations of many marine animals. What is Bycatch?

  4. Different types of fishing practices result in different animal/species being killed as bycatch: nets kill dolphins, porpoises and whales, longline fishing kills birds, and bottom trawling devastates marine ecosystems. The Victims

  5. 100 million sharks and rays are caught and discarded each year. 89% of hammerhead sharks and 80% of thresher and white sharks have disappeared from the North East Atlantic Ocean in the last 18 years, largely due to bycatch. Over 300,000 small whales, dolphins, and porpoises die from entanglement in fishing nets each year, making bycatch the single largest cause of mortality for small cetaceans and pushing several species to the verge of extinction. Over 250,000 endangered loggerhead turtles and critically endangered leatherback turtles are caught annually on longlines set for tuna, swordfish, and other fish. 26 species of seabirds, including 17 albatross species, are threatened with extinction because of longlining, which kills more than 300,000 seabirds each year. The fisheries with the highest levels of bycatch are shrimp fisheries: over 80 percent of a catch may consist of  marine species other than the shrimp being targeted. Bycatch Facts

  9. Fisheries Resources Survey Course 2 August 22, 09:00~12:00 Chi-Lun Wu

  10. Wu, Chi-Lun, Ph.D Current Positions • Researcher, Marine Fisheries Division, Fisheries Research Institute (FRI), Council of Agriculture (COA) Education  • Ph.D. , Oceanographic Institute, National Taiwan University • Master, Oceanographic Institute, National Taiwan University • Bachelor, Department of Aquaculture, National Taiwan Ocean University Experience • Associate Researcher, Mar/1998~Jul/2007, Marine Fisheries Division, FRI, COA • Assistant Researcher, Mar/1990~Jul/1998, Marine Fisheries Division, FRI, COA • Assistant , Aug/1987~ Mar/1990, Fishery Biology DivisionTaiwan Fisheries Research Institute

  11. COURSE OUTLINES • The lecturer of the course- Fisheries resource survey is from Fisheries Research Institute. His name is Chi-Lun Wu. He got his Ph. D. in Oceanographic Institute, NTU in 2001. His dissertation is “Studies on the standardization of abundance indices and stock assessment of South Atlantic albacore”. More than 15 years experience he had, in the assessment of the tuna resource around waters off Taiwan. • In this course, which starts on 22, August, over 50 slides is presented to show the basic concept of fish stock assessment. It covers the characteristics of the fish resource, the estimation of growth parameters and natural and fishing mortality rates, the estimation of maximum sustainable yield using surplus production model, a discussion on the stock/recruitment relationship and the fishery dependent and/or independent data needed in the assessment. Besides, a video tape will prepare to show you the practical operation of the trawler fishery.
