Hoki, hake, ling and warehou species

  • 56 trips observed on 30 vessels where hoki, hake, ling or warehou were

targeted

  • Protected species interactions were recorded from 22 trips onboard 17 vessels
  • Mammal captures were almost exclusively fur seals
  • One young New Zealand sea lion caught but released alive
  • Majority of these fur seal captures were reported from one vessel fishing the

West Coast

  • Tori lines were the most prevalent mitigation device, though some vessels

moved to bafflers in high winds

  • Observer comments indicate that general crew awareness of bycatch issues

was good

  • Nine trips were observed on nine separate vessels
  • Captures occurred on five of these trips
  • Capture rates were for both seabirds and mammals were the lowest for the

past four years

  • Seabirds and pinnipeds observed actively feeding on discharged offal and floor

wash

  • No live captures occurred for either seabirds or mammals
  • Both New Zealand sea lions were males (around 2m in length)
  • Offal management was demonstrated on most vessels, however some

discharged during shooting and hauling.

  • Large quantities of fish meant that vessel meal plants became swamped on

Scampi

  • Four Trips were observed on four separate vessels targeting scampi
  • Protected species bycatch was reported from three of these trips
  • Captures were distributed over three of the four FMAs observed
  • Four of the seven interactions occurred on one vessel (four captures and one

deckstrike)

  • This vessel employed a twin tori line
  • Offal management techniques were employed on vessels however they proved

to be highly variable, both between vessel and over the course of trips

  • Rapid increase in bird abundance during hauling
  • Tori lines were used by all vessels
  • Three vessels used twin tori lines, the fourth used a single line

Squid

  • Twenty five trips were observed on 23 vessels targeting squid
  • Protected species captures were reported from 23 of these trips
  • All but one vessel captured protected species
  • Two hundred and sixty four interactions in total with protected species
  • The majority of captures were net captures
  • Bird Bafflers and Tori Lines were employed as mitigation, however warp

scarers were not used

  • Two vessels accounted for disproportionately high numbers of captures
  • Observer comments highlighted levels of deck lighting, gear

problems and poor net-cleaning to be contributing factors

  • All vessels deployed SLEDs while fishing in 6T
  • Lowest level of HSL captures since 2004/05

  • There was an even split between live releases and mortalities
  • Deck strikes were the most common form of interaction
  • Bird bafflers were the most common mitigation device used
  • Generally fewer marine mammals sighted than in other fisheries according to
  • bserver comments
  • Bird abundance around the vessels was also reported to be lower than in some
  • ther fisheries

Inshore trawl

  • Observers achieved 634 seadays on 36 inshore trawl vessels during the

January/February period 2009

  • Protected species interactions were recorded on 19 vessels.
  • While no mitigation is required, observers reported that mitigation devices were

used on approximately 50% of trawls

  • Forms of warp-deflectors were the most common type of mitigation device in use
  • Highest rate of seabird capture came from SEC
  • A single capture event of 31 spotted shags
  • Offal management was seen to be variable between vessels; as were the

quantities of offal produced

  • Mitigation techniques varied from use of line weighting to tori line and offal

management.

  • Tori lines were of variable construction and were not always deployed

captured

Charter vessels

  • All four foreign charter vessels were observed.
  • 100% observer coverage
  • Seabird and marine mammal captures were observed on all four vessels
  • Effort relatively even between CHA and SOU
  • Higher levels of bird captures in CHA
  • Higher levels of mammal captures in SOU
  • Vessels used between one and three tori lines, some used brickle curtains and

water cannons during hauling.

  • Observers identified a number of factors which could have contributed to

captures, including moon phase and delays during hauling

  • Seventeen trips were undertaken on 12 vessels
  • Protected species captures were reported from 10 of the twelve vessels
  • Two leatherback turtles were captured within 24 hours of each other
  • One bottle nosed whale captured
  • Bird captures dominated by albatross species
  • Overall fewer seabirds caught than the previous year. More mammals and

reptiles caught than the previous year

  • Observer comments indicate a large range in the offal management practices

employed

  • Tori lines operated by almost all vessels
  • Unused and discarded baits observed to be an attractant to seabirds
