Each row is shaded against that species' own best month here, so a dark cell means a good month for that fish rather than a comparison between them.

• Chinook Salmon. Eureka Chinook (Klamath/Trinity and coastal ocean stocks) build through spring and early summer as ocean feeding fish stage off the coast, peaking late July through August when adult fish concentrate near the Klamath and Humboldt Bay mouths before their fall river run. Abundance drops sharply through fall as fish enter freshwater to spawn, with a deep winter trough (Nov–April) when adults are gone and only distant ocean immatures remain.
• Rockfish (Aggregate). Rockfish are resident, non-migratory bottomfish present in Eureka's nearshore reefs year-round, so abundance stays near baseline with no true zeros. A gentle summer-into-early-fall bulge (roughly July–September) reflects settled juveniles recruiting, warmer stable water, and reduced storm-driven displacement that concentrates catchable biomass on the reefs.
• Lingcod. Lingcod are resident on Eureka's nearshore reefs year-round, but abundance concentrates when spawning males guard nests over rocky structure in shallower water. The late-winter/spring peak (Feb–Apr) reflects nesting aggregations, and a second early-fall bump reflects post-spawn recovery and cooler, oxygen-rich upwelling drawing fish back onto accessible reef; midsummer and midwinter show fish dispersed into deeper water, lowering nearshore density.
• Halibut. Pacific halibut migrate onto the shallower nearshore feeding grounds off Eureka as waters warm from late spring through summer, producing a broad May–September abundance plateau with peaks in June and again in late summer. In winter they retreat to deeper offshore waters and are largely absent from the accessible fishing grounds, hence the low baseline from November through April.
• Coho Salmon. Eureka-area coho (Humboldt Bay, Mad/Eel/Trinity systems) are a fall-run stock that stage off the coast and enter the estuary with the first significant fall rains, peaking late September through October (weeks 39-42). They are biologically absent from these waters the rest of the year, with adults leaving marine/estuarine zones by early winter after upstream migration.
• Cabezon. Cabezon are resident nearshore reef/kelp dwellers around Eureka year-round, so abundance stays broadly near baseline. The clear peak in late spring through early summer (May–July) reflects nest-guarding males staying tightly on shallow rocky structure and increased catchability, with a mild post-spawn dip and lower winter presence as fish disperse to deeper, less accessible reef during storm-driven cold months.
• Albacore tuna. Albacore are a warm-water offshore migrant that reach Eureka only when the 58-64°F blue water pushes within range, typically arriving mid-to-late July, peaking August through mid-September during warmest SST and settled seas, then thinning out by mid-October as water cools. They are biologically absent from these northern California waters the rest of the year.
• Albacore Tuna. Pacific albacore are a warm-water pelagic migrant that arrive off Eureka only when offshore water warms and the blue water pushes within range, typically mid-July through September with a peak in August–early September. They are biologically absent from these cold Humboldt waters through winter and spring, hence the long zero stretch.
