Depending on how kina is collected it can be a good seafood choice. If collected by diving (breath-hold) then it is good to eat, but if collected by dredging then it is a worst choice and should be avoided.
Kina are an important grazing species found throughout New Zealand. Most are harvested by breath-hold diving, with a smaller proportion being caught by targeted dredging in Marlborough.
Kina is caught mainly by diving with less than 10% caught by dredging in Marlborough. There are concerns over the unknown sustainability of current catch levels or limits, the risk of serial stock depletion due to the lack of stock assessments, impacts on reef communities from changes in grazing levels, limited research and the lack of a management plan. When dredged, considerable habitat damage can occur.
Not certified under any scheme.
Kina are sold in New Zealand and exports of $746,000 mainly to Australia (95%) and China.
Kina caught by breath-hold diving and dredge were assessed, which led to differences in regions being assessed. Kina caught throughout New Zealand by breath-hold diving is a good seafood choice and rated amber, while kina caught by dredging was ranked red and should be avoided.
|Score:||Both diving and dredge – D|
|Annual catch limit:||Limit set at 1147 tonnes since 2003.|
|Recorded catch:||Reported catch of 885 tonnes for all fishstocks in 2014-15, with the main catches in Southland/Fiordland, Hauraki Gulf-Bay of Plenty, and Marlborough Sounds.|
|The Ministry of Primary Industries assessment plenary report includes:||“For all Fishstocks it is not known if current catch levels or TACCs are sustainable, or if they are at levels which will allow the stocks to move towards a size that will support sustainable yields.” (MPI 2016, p 590-591).|
|Score:||Both diving and dredge – C|
|Distribution:||Throughout New Zealand and the sub-Antarctic Islands.|
|Maximum age (years):||20+|
|Age at sexual maturity:||4-5|
|Age exploited:||8-9 (uncertain)|
|Ability to recover:||Moderate|
|Score:||Diving – A, dredge – E|
|Fishing method(s):||Most kina are harvested by breath-hold diving, with a smaller proportion (10%) being caught by target dredging in Marlborough Sounds.|
Dredge: Scrapes the seafloor killing or damaging bottom-dwelling species.
|Habitat of particular significance:||hasn’t been defined in New Zealand.|
Dredge: Has a high bycatch including a range of bottom dwelling species, but no reported protected, threatened or endangered species.
|Ecological effects:||Changes in kina numbers have effects on algal community assemblages. Impacts will depend on scale and intensity of harvesting. Dredging for kina has considerable ecological implications as it destroys seafloor communities, which could affect associated midwater species.|
|Score:||Both dive and dredge – A|
|Bycatch:||None from diving. Dredging has not reported any bycatch of protected, threatened or endangered species.|
|Management component:||Single species, but the stock structure and source of larval dispersal for populations are uncertain.|
|Quota Management Species:||Yes, since 2002 (South Island) and 2003 (North Island).|
|Management plan:||There is no approved inshore plan.|
|Stock assessment:||No stock assessments for quota areas. Biomass estimates have been made for limited areas – Arapawa Island (1997) and Dusky Sound and Chalky Inlet (1995).|
|Research:||There is no directed research on kina.|
