Northern pike (Esox lucius) were put in tanks with fantail and regular-tail goldfish (Carassius auratus) or with goldfish of different colors. Physical appearance of prey did not affect the pike’s feeding. In experiments in plastic pools four species of fish were exposed to predation by northern pike that were satiated or deprived of food for either 2 or 4 weeks. The pike always selected carp (Cyprinus carpio) and fathead minnow (Pimephales promelas) over green sunfish (Lepomis cyanellus) and bluegill (L. macrochirus).

To compare vulnerability to predation by northern pike (Esox lucius Linnaeus), several species of fish in various combinations were held with pike in plastic swimming pools with and without cover and in small ponds. The most vulnerable species in order were gizzard shad (Dorosoma cepedianum), carp (Cyprinus carpio), bigmouth buffalo (Ictiobus cyprinellus), fathead minnow (Pimephales promelas), and smallmouth bass (Micropterus dolomieui). White sucker (Catostomus commersoni), green sunfish (Lepomis cyanellus), largemouth bass (Micropterus salmoides), golden shiner (Notemigonus crysoleucas), and yellow perch (Perca flavescens) showed intermediate vulnerability. Channel catfish (Ictalurus punctatus), northern pike, bluegill (Lepomis macrochirus), and black bullhead (Ictalurus melas) were least vulnerable. In two experiments in which fish were put in cages in turbid water, relative vulnerability was the same as in clearer water. Pike could not be conditioned to eat golden shiner or bluegill. There was a tendency for certain sizes of pike to select the smaller carp, fathead minnow, and bluegill within the size ranges tested.

Web Structure

In May 1993 and 1994, northern pike (Esox lucius) were added to eutrophic Lake 227 and oligotrophic Lake 110 at the Experimental Lakes Area in northwestern Ontario. Both lakes were previously dominated by cyprinids, and northern pike additions significantly decreased cyprinid densities in both lakes. Food web relationships were determined pre- and post-manipulation using stable carbon (δ13C) and nitrogen (δ15N) isotope analyses of zooplankton, benthic invertebrates, and fishes. In Lake 110, fathead minnow (Pimephales promelas) shifted from a zooplanktivorous to a zoobenthivorous diet as indicated by a shift in isotopic composition to more depleted δ15N and enriched δ13C values after northern pike additions. It was not possible to direct predator-induced shifts in cyprinid diets in Lake 227. Concentrations of mercury and organochlorines (sum of polychlorinated biphenyls (ΣPCB), dichlorodiphenyltrichloroethane (ΣDDT), and hexachlorocyclohexane (ΣHCH)) in these fish did not change markedly after northern pike introductions despite the shifts in diet for fathead minnow from Lake 110. However, concentrations of all contaminants were lower in biota from eutrophic Lake 227 when compared with Lake 110, which is consistent with previous studies. Our results indicate that nutrient availability, rather than short-term changes in food web structure, determined contaminant concentrations in fish and other biota from these lakes.

Before And After

We studied the cadmium concentrations in water, sediment, suspended particles, a free-swimming insect larva (Chaoborus), a sediment-bound insect larva (Chironomus), and liver of northern pike (Esox lucius) before and after liming operations in Lake Långsjön, Sweden. In accordance with the higher pH levels obtained in the lake water after the limings, cadmium concentration decreased in the water but increased in the sediment. Cadmium concentration in fish liver and Chironomus decreased after the limings whereas the concentration in Chaoborus larvae increased after the first liming. Possible mechanisms are discussed.
