The feeding behaviour of the kelp clingfish Rimicola muscarum Meek and Pierson residing on the blades of the kelp Macrocystis integrifolia Bory was described. The fish seized small invertebrates, mainly harpacticoid copepods, which were closely associated with the kelp blades. A four-step food chain involving R. muscarum was qualitatively determined. Diatoms epiphytic on the kelp blades were grazed by harpacticoid copepods. These and other small invertebrates were captured by the clingfish, which in turn was eaten by the black rockfish, Sebastes melanops, and the shiner perch, Cymatogaster aggregata.

Abstract The idea behind the various papers called Food for Thought was to show how advanced researchers developed their careers, informing about successes and misfortunes. This presentation reports not only on the experiences made by the author; it includes those researchers who provided ideas and support for the author which then led to progress. It often occurs that cooperative efforts are actually needed to advance. The interdisciplinary oceanographic studies reported here were made possible by truly cooperative planning and data-sharing efforts of several individuals which then led to our pioneering advances. Similarly, the successes on obtaining the actual feeding behaviour data of calanoid copepods, after decades of guesswork, could only be achieved through cooperation. Much of the credit goes to my colleagues at the Food Chain Research Group at Scripps Institution of Oceanography who pioneered the combination of field and laboratory efforts to arrive at an understanding of biological processes in the ocean. Overall, not so much my initiative-taking but the repeated encouragement by and feed-back from my colleagues and friends both at Scripps, at Skidaway and other institutes made advances possible.

General laws in ecological parasitology are scarce. Here, we evaluate data on numbers of fish parasites published by over 200 authors to determine whether acquiring parasites via prey is associated with an increase in parasite aggregation. Parasite species were grouped taxonomically to produce 20 or more data points per group as far as possible. Most parasites that remained at one trophic level were less aggregated than those that had passed up a food chain. We use a stochastic model to show that high parasite aggregation in predators can be solely the result of the accumulation of parasites in their prey. The model is further developed to show that a change in the predators feeding behaviour with age may further increase parasite aggregation.

Between December 2004 and January 2007, we studied the movements of six Black Rockfish (Sebastes melanops) that had been fitted with acoustic transmitters and reintroduced into a fjord environment at the edge of Vancouver Harbour, British Columbia. The Black Rockfish were released in December 2004 and April 2005 at a reef characterized by complex rocky structures and steep slopes; bottom depths at the site dropped from 10 to 55 m within a horizontal distance of only 30 m. The reef, however, is small (approximately 4500 m2) and is surrounded by soft bottom habitats used infrequently by Black Rockfish. VEMCO VR2 receivers were deployed at the release site and at outlying reefs located 1 and 4 km away. Acoustic data suggest that one individual emigrated from the reef after 11 months of residency and a second individual disappeared abruptly after 6 weeks on the reef, possibly due to fishing mortality or emigration. The four remaining individuals appear to have confined their movements to the release site, using an area 6 to 10 times smaller than the home ranges reported for populations in low-gradient coastlines in California and Oregon.
