. Bulletin. Science. FISHERY ON NORTHERN PACIFIC COAST OF BAJA CALIFORNIA 53 32c 30c 116° 114° U. S. - Mexican Border Bahia Todos Santos Punta Banda Punta Santo Tomas Erendira Cabo Colonet Camalu N 100 km 28° Pacific Ocean. Bahia San Quintin — Punta Baja Bahia de Rosario Puerto San Carlos Punta Canoas Fig. 1. Sampling sites for the artisanal fishing during 1994 and early 1995. de San Quintin (Rosales-Casian 1997b), and was measured by four bottom rep- licates (lOm-depth) during all monthly trips with a reversible thermometer. A Pearson correlation between bottom temperatures and fish abundance (loglO[X+l] transformed) from all sites and from San Quintin was calculated to measure their association (Zar 1984). Abundance was converted to catch per unit effort (CPUE) by dividing the number of fishes by the number of boat trips. The boat catches were first examined for assumption of normality (K-S, d = , p>) and then were loglO(X+l) transformed to determine seasonal differences in mean catches by an Analysis of Variance (ANOVA). To determine the contribution of each species to the catch and which could be considered target species, the Index of Community Importance (ICI) was used (Stephens and Zerba 1981; Love et cil. 1986; Rosales-Casian 1997a,b). The ICI was calculated by the sum of the percent of abundance and frequency-of-occur- rence rankings. Species were then reranked based on these ICI values. The standard lengths (mm) were grouped by 20 mm classes. Length-class dis- tributions were presented for all individuals and seasonally for the three more important target fish species. Sizes were transformed to logarithms to determine seasonal differences by ANOVA, as above. Results The means of seasonal bottom temperatures at lOm-depth from the coast of San Quintin were , , , and °C for spring, summer, fall, and winter, respectively. The catch presented here reflects the fishes and sizes of commercial. Please note that these images are ex
