Fish predation on 0-group flatfish (plaice Pleuronectes platessa, dab Limanda limanda and flounder Pleuronectesflesus) populations on Tralee Beach. Scotland (56" 31' N, 5" 29' W) was studied by stomach content analysis during the summers of 1992 and 1993. I-group grey gurnard Eutrigla gurnardus, poor-cod Trisopterus minutus and whiting Merlanyius inerlangus and 0-group cod Gadus rnorhua were the major fish predators of the 0-group flatfishes. Flatfishes >45 mm total length appeared to have a refuge in size from predation by the fishes sampled. Predation by fishes was shown to be negatively size-selective, concentrated on the smaller size-classes of flatfishes. Smaller individuals were eaten by a greater taxonomic variety and a larger size range of predators than larger flatfishes. Smaller flatfishes'were therefore vulnerable to a larger number of predators. The size distributions of predators affected the pattern of predation because only the larger individuals ate flatfishes. It is therefore proposed that the degree of overlap in the size distributions of predators and prey determine the magnitude of predation. Growth rates and the timing of settlement in any one year will therefore have a considerable influence on predation, with the potential to result in a 'match or mismatch' of predator and prey size distributions.

“…Its early life history in nature (Okiyama 1967;Tanaka et al 1989) and developmental process in rearing tanks have been elucidated (Fukuhara 1986;Seikai et al 1986), and protocols for the rearing of the species have been established. Moreover, physiological information during metamorphosis has been accumulated on the Japanese flounder , suggesting that the species would be a good model for studying the ontogeny of the asymmetry of flatfishes at the molecular level.…”

The symmetrical body of flatfish larvae dramatically changes into an asymmetrical form after metamorphosis. Eye migration results in the most significant asymmetrical development seen in any vertebrate. To understand the mechanisms involved in eye migration, bone and cartilage formation was observed during metamorphosis in laboratory-reared Japanese flounder, Paralichthys olivaceus, by using whole-body samples and histological sections. Most of the hard tissues of the cranium (parasphenoid, trabecular cartilage, supraorbital canal, and supraorbital bar) exist symmetrically in the larval period before metamorphosis and develop by twisting in the same direction as that in which the eye migrates. An increase in skin thickness beneath the eye was observed only on the blind side at the beginning of eye migration; this was the first definitive difference between the right and left sides of the body. The pseudomesial bar, a peculiar bone present only in flatfishes, developed from this thick skin and grew dorsad. Novel sac-like structures were found and named retrorbital vesicles. The retrorbital vesicle of the blind side grew larger and faster than that of the ocular side when the right eye moved most dramatically, whereas no difference was observed between the volume of right and left connective tissue in the head. The asymmetrical presence and growth of the pseudomesial bar together with inflation of the retrorbital vesicle on the blind side may be responsible for right eye migration during metamorphosis in the Japanese flounder.

“…Rapid growth is particularly important for newly settled fish which can suffer high mortality rates that typically vary inversely with body size (Victor 1986, Tanaka et al 1989, Beverton & Iles 1992, Gibson et al 1995, Sogard 1997, Schmitt & Holbrook 1999, Shima 2000. As a result, variation in the suitability of nursery habitats for early juvenile growth can strongly influence patterns of post-settlement survivorship.…”

ABSTRACT:The relationship between the growth of early juvenile winter flounder (Psuedopleuronectes americanus, Walbaum; 17 to 27 mm standard length [SL]) and the spatial dynamics of estuarine gradients immediately following larval settlement was examined using field enclosure techniques in a temperate nursery. Enclosures (n = 60; 3 fish per enclosure) were deployed throughout the Navesink River/Sandy Hook Bay estuarine system, New Jersey, in a nested spatial design that allowed measurement of growth variation in time at 3 spatial scales (between regions: × -distance [D]
