| dc.description.abstract | Experiments were conducted to study the habit at selection of
juvenile cod Gadus morhua, juvenile whiting merlangus merlangius,
black goby Gobius niger, great pipefish Syngnathus acus,
sand eel Ammodytes tobianus, butterfish Pholis gunnellus, three-spined
stickleback Gasterosteus acculeatus, sea stickleback
Spinachia spinachia, goldsinny Ctenolabrus rupestris, and
flounder Plathichthys flesus. Aquaria with compartments with
algae, with sand and with no substratum were used.
Cod, whiting and great pipefish preferred the empty compartments
followed by the compartments with sand. For the other
species no significant differences were observed althouqh
butterfish, three-spined stickleback, and sea stickleback were
most frequently found in compartments with algae, and black goby
and sand eel were most frequently found in the compartments with
sand.
The experiments also showed that cod and whiting had a
significant attraction to each other. | en |
