Title: FAR 2018/09 - Relative abundance, population structure, and stock status of blue cod in Paterson Inlet in 2014. Concurrent fixed and random site potting surveys
FAR-2018-09-BCO5-Paterson-Inlet.pdf
(3.0 MB)
The third fixed and second concurrent random site potting survey in the time series for Paterson Inlet. Sixty-three sites were surveyed (6 pots per site, 378 pot lifts) from 5 strata. Pot catch weighed, length and sex of blue cod recorded. Otoliths from random and fixed sites produced age-length keys applied to the scaled length frequency distributions to estimate the population age structures. Estimates of Z and F%SPR indicate that spawning biomass has been reduced to 30-39%.

(3.8 MB)
Second random site potting surveys in the time series. Forty potting sites surveyed (6 pots per site = 240 pot lifts) from six strata. Pot catch weighed, length and sex of blue cod recorded. Otoliths age-length keys applied to the scaled length frequency distributions estimate population age structures. Estimates of Z and F%SPR indicate spawning biomass reduced to 57% (inshore) and 74% (offshore). Density/pot catch relationships differ among areas imply pot catchability is spatially variable.

Third fixed and first random site potting surveys in north Otago time series. Twenty-seven fixed and 40 random sites surveyed (6 pots per site, 402 pot lifts) from 4 coastal and 2 offshore strata. Pot catch weighed, length and sex of blue cod recorded.

Third fixed, first random site potting surveys in the time series. Eighty-eight sites surveyed, 6 pots per site, 528 pot lifts. Pot catch weighed, length and sex of blue cod recorded. Otoliths age-length keys applied to the scaled length frequency distributions to estimate population age structures. Estimates of Z and F%SPR indicate spawning biomass has been reduced to 52% in Kaikoura and 44-45% in Motanau. Density estimates from video transects had only a poor relationship with pot catches.

Concurrent fixed and random site potting surveys (80 sites, 6 pots/site) from 5 inshore and 2 offshore Banks Peninsula strata. Catch rates and size frequency are compared with 4 previous fixed site surveys, and comparisons made between survey designs. Otoliths were collected for age compositions, total mortality estimates, and spawner per recruit analyses. Concurrent video transects had an extremely poor relationship with observed density and subsequent pot catches of blue cod less than 30 cm.

An Aerial-Access survey method was used to estimate the recreational harvest of snapper and blue cod taken from Golden Bay, Tasman Bay and the Marlborough Sounds during the 2015–16 fishing year. The harvest estimates for these species were of a similar magnitude to those estimates by a National Panel Survey conducted in 2011–12. Harvest estimates were also calculated for rock lobster and scallops, but these are not considered to be reliable for these particular species, as related fishing effort is not readily quantified from the air.

This report describes the results of blue cod (Parapercis colias) fixed and random site potting surveys carried out concurrently off Motunau in January 2016. Estimates are provided for population abundance, size and age structure, sex ratio, total mortality (Z), and spawner-per-recruit. This is the fourth survey in the Motunau fixed site survey time series following surveys in 2005, 2008, and 2012; and the second random site survey with the previous survey in 2012.

12_43_FAR.pdf
(1.4 MB)
This report describes the 2010 Marlborough Sounds potting survey of relative abundance, population length and age structure, and stock status of blue cod. Observations of blue cod from remote drift video transects were compared with the 2010 potting survey catches. Analyses included catch rates, catch-at-age, total mortality (Z), and spawner-per-recruit (SPR). Historical surveys of Marlborough Sounds (2001, 2004, and 2007) and Cook Strait (2008) were also analysed and time series comparisons made.

Title: Relative abundance, size and age structure, and stock status of blue cod in Foveaux Strait in 2010
12_39_FAR.pdf
(1.2 MB)
The 2010 Foveaux Strait blue cod random site potting survey mean catch rate was 4.8 kg.pot-1, c.v.=11.3%. Size ranged from 11 to 56 cm, though few were >40 cm. The mean age was 7.1 years for males and 6.9 years for females and Z ranged from 0.34 to 0.46. SPR was F35%, which is above the target reference point. Concurrent video counts had more small blue cod and a correlation of 0.50 suggests the relationship between catch and count is variable. Blue cod were most associated with sponge habitats.

Title: Relative density of blue cod (Parapercis colias) in Milford and Doubtful Sounds in response to spatial management
12_36_FAR.pdf
(7.4 MB)
Baited underwater video surveys within designated management zones of Milford Sound and the Doubtful Sound complex found low numbers of blue cod and tarakihi. The overall conclusion is that blue cod are not abundant at any locations inside Milford Sound or the Doubtful Sound complex regardless of marine reserve or temporary fishing closure designations.
