The Rock Lobster Catch Sampling (rlcs-a) database contains catch sampling information on New Zealand rock lobster species (red and packhorse) collected as part of research projects.

The rlcs-a database predominantly contains catch sampling data related to rock lobster catch samples, for both rock lobster species. Additionally, it contains morphological measurement data (including some market sampling data). It has been created in response to a need to maintain a time series on biological and CPUE data independent from the industry daily landing logs.

Sampling frequency: variable. Database records start in 1969 and continue to present.

Number of sites: variable.

Extent of site: EEZ coastal area.

Number of replicates: N/A.

Measured variables: Data are recorded on the Pot Catch Form and include the number of lobsters caught (both dead and alive), pot type, depth, soak time, bait, and an escape gap code. Biological data for individual rock lobsters recorded on the Length Frequency Form, include sex, carapace length, and tail width (across the spines on the second abdominal segment), tail length, weight, injuries, moult and run states, and the red rock lobster status (whether it was landed to a Licensed Fish Receiver (LFR)).

Capture method: lobster pot

Sampling protocol & QA: The rlcs database enforces data validation and integrity with use of referential constraints and range checks. The data go through a rigorous data validation and error checking process before being entered.
