Fig 1.
Total catch calculations from MRIP surveys.
Information came from telephone effort surveys (outlined in green) or intercept surveys (outlined in orange), and correspond with the variables in Eq 5.
Table 1.
Data come from MRIP telephone surveys in 2004–2013. Data are summarized as mean and standard deviation of values per wave (i.e., for the 60 2-month periods in that 10-year period). Participation rate is proportion of households in which someone fished in the preceding wave; trips per household represents the number of fishing trips per fishing household in that period. Total # trips was calculated using Eq 1. Number of households ranged from 63,209 to 64,909 for Hawaiʻi Island, 21,968 to 22,390 for Kauaʻi, 1,068 to 1,074 for Lānaʻi, 43,505 to 49,080 for Maui, 2,525 to 2,561 for Molokaʻi, and 303,794 to 309,803 for Oʻahu.
Table 2.
Data come from MRIP telephone surveys in 2004–2013. Data are summarized as mean and standard deviation per island and wave of the percentages of fishing trips per combination of platform (boat or shore) and gear as defined by Eq 2. Gears have been pooled into line, net, spear, or not-reef (offshore, pelagic or bottomfish fishing), as described in S2 Table.
Table 3.
Recreational CPUE per island, platform, and gear.
Data shown are mean and standard error (SE) of CPUE by island for each combination of island, platform, and gear in intercept surveys by MRIP between 2004–13. Eqs 3 and 4 were used to calculate mean and variance of CPUE values. Reef fishes are taxa as defined in S1 Table. Note that as there were no intercept surveys on Lānaʻi, CPUE data for there are assumed to be the average from other islands. Lānaʻi CPUE SE was generated using the average precision (SE/mean) from all other islands. The number of catch interviews per combination of island, platform, and gear is given in S3 Table.
Table 4.
Total catch by island in kg year-1.
Values show estimates of commercial and non-commercial catch for each island, as well as a statewide total and combined catch. Yearly estimates are from the time frame of 2004–2013. ‘Other’ for CML comes largely from Niʻihau, which has a resident population of ~100 people and is ~30km from Kauaʻi; but also includes catch from offshore banks and pinnacles.
