“…Namely, the histochemical characteristics of pink muscle fibers in both ordinary and intermediate muscles were very similar. The same findings were reported in the rainbow trout (Johnston et al, 1975), and we reported that the temporal change of K-value in the dorsal ordinary muscle of carp was accelerated by the interposition of pink muscle fibers (Yada et al, 2000). It was therefore thought that the interposition of pink muscle fibers into the ordinary muscle might cause a temporal change in K-value (one item of the freshness index), which might be explain the difference in the increasing K-value rate among fish species.…”

The difference in interposition ratio of pink muscle fiber among various fish species was studied to learn its influence in dorsal ordinary muscle on the post-mortem change of K-value. A remarkable mosaic pattern was exhibited in the interpositioned white and pink muscle fibers in many of the species. The relative number and area percentages of these fibers to all muscle fiber types differed greatly among fish species, and distributed from 12.9% to 56.53% in a number, and from 2.22% to 53.68% in an area. The relationship between the area and numerical percentages had significantly high positive correlation. Size of the pink muscle fiber was somewhat smaller than that of white muscle fiber.Keywords: dorsal ordinary muscle, interposition ratio of pink muscle fiber, size of pink muscle fiber, fish species Organization of the dorsal skeletal muscle in fish is arranged in three distinct layers of dark muscle, intermediate muscle, and ordinary muscle. Each of these is organized in a single muscle fiber type as follows: red muscle fibers (Type I), pink muscle fibers, and the white muscle fibers (Type II), respectively (Johnston et al., 1974;Gill et al., 1982;Carpene et al., 1982;Hoyle et al., 1986). The red muscle fiber is small in diameter and relies on an aerobic form of metabolism, while the white muscle fiber has a large diameter and operates principally by anaerobic glycolysis. Functionally, the former is implicated in sustained slow swimming and the latter is in bursts of violent activity (Matsuoka & Iwai, 1984). The white muscle fibers are subdivided into Types IIa and IIb, the IIa subtype being used not only for anaerobic metabolism but also for aerobic metabolism, and the IIb subtype especially for anaerobic metabolism in response to typical escape and attack movement; the pink muscle fiber is more particularly for aerobic metabolism than the IIa subtype (Jabarsyah et al., 1999a). The pink muscle fiber is characterized as fast contracting with intermediate resistance to fatigue and intermediate speed of shortening between red and white muscle fibers (Johnston et al., 1977). Most histochemical studies in fish muscle have involved these distinct layers, and only a few studies have dealt with the differences in fiber types in ordinary muscle among various fishes. Korneliussen et al. (1978) and Walesby and Johnston (1980) reported that a boundary region between the layers of intermediate muscle and ordinary muscle was not remarkable in the cod Gadus morhua, and that the Antarctic toleost Notothenia rosii had no pink muscle fiber in its locomotory muscles. In our previous study, we reported that there were not only white muscle fibers but also pink muscle fibers in the dorsal ordinary muscle of many fish species, and that the fiber type in this muscle was differed remarkably among species, between wild and cultured fish of the same species, and among regions along the length of the body and toward the neural spine (Jabarsyah et al., 1999a).We also reported that the presence of pink muscle fiber in the ordinary musc...

“…Forstner et al (1983) observed several changes in muscle development in coregonid larvae reared at 10°C. The authors observed a thin layer of 'small diameter red fibres' (described by Johnston et al 1975) from Day 4 on, which made up to 9% of the total muscle mass on Day 20. Increase in this muscle mass was realised by increasing cell numbers and not by increasing the diameter of the cells, so hyperplasia can be assumed to be present in this type of muscle.…”

Somatic growth and nucleic acid content were studied in North Sea houting Coregonus oxyrhinchus larvae fed exclusively on dry diets at 2 temperatures (8.4 and 17.5°C) during a 32 d rearing experiment. The higher temperature enhanced growth significantly. Mean dry weights at the end of the experiment were 3.6 mg (SD = 1.07, range 1.4 to 5.7 mg) and 31.5 mg (SD = 21.9, range 3.6 to 96.0 mg), and mean standard lengths were 17.7 ± mm (SD = 1.6, range 11.8 to 19.6 mm) and 25.5 mm (SD = 4.2, range 17.0 to 35 mm), respectively. Significant responses to temperature were also found in the nucleic acids. However, these differences were not as remarkable and gave indications that differences in protein growth between treatments was based on protein biosynthesis being driven by the activity of the ribosomes, rather than their number. The use of the degree-day approach to normalize the data clearly showed the temperature-dependence of somatic growth. Only small differences in growth and nucleic acid content were observed in the comparable range of the first 280 degree-days in fed fish. In non-fed fish, the starving potential was very similar (approx. 350 degreedays). Shifts in growth pattern from predominantly hyperplasia to predominantly hypertrophy were detected, with ongoing growth at both temperatures.

“…The myotomal muscle of teleosts contains two main fibre types, grouped in two layers: (1) subdermal red muscle, with oxidative metabolism and slow contraction, and (2) deep white muscle, with glycolytic metabolism and fast contraction (Johnston et al 1975(Johnston et al , 1977Bone 1978). Between those layers, an intermediate zone is found, with fibres characterised by being essentially fast contracting, with both intermediate resistances to fatigue and shortening speed (Johnston et al 1977).…”

Muscle cellularity was studied in Pagellus bogaraveo juveniles fed on diets with different protein contents. Measured in transversal body sections, at both post-opercular and post-anal locations, the morphometric variables estimated were: total muscle area (A), total number of fibres (N), number of fibres per unit area of muscle (N A ) and cross-sectional fibre area ð" aÞ; of the two main muscle fibre types. At the end of the experiment fish fed on diets having more than 40% of protein displayed significantly higher body weight. Fish fed on protein-rich diets exhibited greater " a and N. For fish fed on 30 and 50% protein diets the morphometric parameters measured grew linearly with the fish weight. High-protein diets favoured muscle hyperplasia. When comparing rostral and caudal locations, a greater N and a smaller " a of posterior red fibres were the consistent differences found-a fact, to our knowledge, so far unreported for fish.
