  1. Preliminary Assessment of the Handline Fisheries in the Philippines 14th NATIONAL TUNA CONGRESS September 7, 2012 Funded by the Australian Centre for International Agricultural Research

  2. Region V - Bicol

  3. Gear Classification Lines: A. Handlines (“kawil”) 1. Simple handlines or drop lines (“kawil”) 2. Multiple handlines (“kawil-moderno”) 3. Jiggers (“hila-hila”) 4. Pole and lines (“binwit o biwas”) 5. Troll lines (“sibid-sibid o pahila”) B. Longlines (“kitang”) 1. Set longlines (“palagiang-kitang”) 2. Drift longlines (“kitang-paanod”) Umali, 1952

  4. Gear Classification Lines – device consisting of baited hooks attched to a line or lines which fish on the principle that fish fall victims to baits. A. Handlines (“kawil”) - long simple lines with only a small series of baited hooks requiring constant attention. 1. Simple handlines or drop lines (“kawil”) - a single vertical line carrying 1 or 2 barbed hooks and worked by simply dropping it into the water and waiting for a fish to bite.

  5. Gear Classification 2. Multiple handlines (“kawil-moderno”) - a single vertical line with a series of barbed hooks attached to it by spreaders at regular intervals.

  6. Gear Classification • 3. Jiggers • - lines, each bearing a multiple-hooked device, which are worked by jerking up and down under bright light, amking hooked lures attractive to squids • 4. Pole and lines • - handlines attached to a pole

  7. Gear Classification • 5. Troll lines • - long handlines, fished horizontally with a hook or hooks at the free end, baited with either a natural or artificial lure, and the whole arrangement towed behind a boat underway.

  8. Gear Classification Hook and Lines: A. Handlines (“kawil”) - is used to capture deep swimming tunas, principally yellowfin but also bigeye. Handlining is usually practiced while the banca is tied on a payao set in deep water. There is only one (1) hook used per line but up to six (6) lines maybe operated from the same vessel at one time. De Jesus, 1982

  9. Gear Classification B. Longlines (“kitang”) - used to catch deep-swimming tunas - mainlines, bouylines and branchlines are tied together - originally of Tawanese origin De Jesus, 1982

  10. Gear Classification C. Troll lines - used for surface schools of small tunas - two bancas move towards the school and away from each other, paying out the troll line within them De Jesus, 1982

  11. Port Sampling • Port sampling data were gathered in the following sampling sites: • Tabaco City, Albay • Sugod, Tiwi, Albay • Nato, Sagñay, Camarines Sur • Sabang, San Jose, Camarines Sur • Period Covered: September 2009 - August 2010

  40. Region X11 – Gen. Santos City

  41. Background • General Santos is also known as the “Tuna Capital of the Philippines” due to its high volume of fish unloaded everyday that can surpass that of any other fish port or even the entire unloading of all other fish ports in the country combined (Aprieto, 1995). • tuna handline fishing started in the year 1970 along the territory of Sarangani Province and General Santos City • From 1970 to 1980s, there were only around 500 handline boats operating. • The number of handline boats continued to increase until it reached its peak in the mid-1990’s with around 2,500 handline vessels. • In the late 1990’s, the number of handline vessels started to decrease. • Today, it is believed that there are only 1, 100 handline vessels operating

  49. Threats to the handlinefishery in General Santos • competition from other fisheries; • declining stocks; • ineffective management arrangements; • lack of accurate data; and • environmental degradation

  50. Key Challenges in the handlinefishery in General Santos • Decreasing catch by handline vessel affecting the supply of fish to tuna canneries; • Ineffective fish handling techniques onboard vessels resulting in poor quality product; • Difficulty in competing in the international market of tuna; • Lack of effective registration and licensing system; • Lack of access to fishing grounds outside Philippine national waters.
