“…The presence of anchovy and sandlance strongly support the production of piscivorous fishes. Utilization of sandlance has been observed in Japanese temperate bass Lateolabrax japonicus (Kosaka 1969) and the snailfish Liparis tanakai (Kawasaki et al 1983) in Sendai Bay. Japanese anchovy is consumed by many piscivorous fishes, such as white-spotted conger Conger myriaster (K. Goto unpubl.…”

“…This is probably not a significant problem in openocean areas, but may be important in small lakes or relatively closed embayments. This is also a problem with annual predator species, but there are very few of these in the marine environment -the snailfish Liparis tanakai is probably the only annual species in this study (Kawasaki et al 1983). In longer-lived species, it is sometimes possible to obtain data on several year classes simultaneously, and this is another great advantage of the BRF data, but is true of some of the other data sets (especially 'B' data sets) as well.…”

Traditional approaches to diet analysis in fish established that niche breadth increases as the fish grows. However, this appears to be artefactual, influenced by sampling, measurement, and statistical difficulties. On a ratio scale, niche breadths appear to be characteristic of a species and (generally) constant as the fish grows. In general there seems to be no equivalent to Roughgarden's 'between-phenotype-component' in ratio-based niche widths of fish. From the data available, there also appears to be no consistent trend of niche breadth among fish predator species of different mean sizes. Similarities to and differences from Ursin's log weight-ratio analysis are discussed. Assuming equal or predictably declining prey biomass in equal logarithmic length intervals (a Sheldon spectrum), a constant logarithmic (ratio) niche breadth means a constant or declining effective prey biomass pool as predators become larger. This contrasts with the generally expanding prey biomass pool postulated in the size-efficiency hypothesis. When prey biomass equilibrium can be assumed, declining productivity with size will further reduce resources available to increasingly large predators. A declining resource base would act to offset any size-related gains in metabolic or foraging efficiency.

“…This is the first study to demonstrate the predation by L. tanakai and O. punctatus on released juvenile P. olivaceus . Liparis tanakai mainly feeds on shrimps and fishes, including flatfishes (Kawasaki et al , 1983; Kobayashi & Hiyama, 1991). Wild P. olivaceus were found in five stomachs of L. tanakai 221–433 mm L T collected in the surveys from September to December.…”

“…4) and actual predation on released P. olivaceus was observed only in November (Table I). This species has a 1 year life span and grows rapidly until winter (Kawasaki et al , 1983). Thus, releases in summer would greatly reduce the predation risks by L. tanakai , although predation by this species on wild juveniles <100 mm was observed in summer and autumn.…”

To determine the predators of 100 mm total length hatchery-reared juvenile Japanese flounder Paralichthys olivaceus, fishes and crabs were collected using gillnets and a small trawl net off the coast of Fukushima Prefecture, Japan. Predation on juvenile P. olivaceus by older conspecifics, the snailfish Liparis tanakai, ocellate spot skate Okamejei kenojei and the swimming crab Ovalipes punctatus, was detected based on analogical observation and molecular techniques. These predators are nocturnal feeders except for P. olivaceus. Liparis tanakai with body sizes large enough to consume juveniles only appeared in winter, whereas the large O. punctatus was abundant in early summer and in late autumn. Such seasonal variation in predator abundance indicates that the release season can be optimized for reducing predation mortality.
