The length-weight relationship of lsoparorchis hypselobagri was calculated from a total sample of 562 specimens from three size groups - smaller (11-19), intermediate (20-31) and larger (32-48 mm). The equation for the relationship was calculated as log W = 1.9273 log L = 0.1346 or W = 0.7335 L¹'⁹²⁷³ (r = 0.9973; P < 0.001). Variation in the regression coefficient (b) from different length groups reflected variation in the physiological conditions of the flukes.

Length and weight growth rates of 206 bream individuals caught in 1992 and 1995 were back-calculated. Different types (non-linear vs. linear) of a relationship between the scale caudal radius and body length were revealed to prevail in the two years. The 1992 bream grew very rapidly during the first four years of life, the growth rate slowing down later on. On the other hand, the bream growth in 1995 was more uniform over time. No sex- or age-dependent differences in growth rate were found. The Lake Dšbie bream population belongs to the fast growing populations of the species.

The cycloid scales reveal the presence of a distinct larval mark under the scanning electron microscope. A linear relationship between total fish length and lateral scale radius was observed. The exponent of the length-weight relationship was 2.519 and 3.094, the harvestable size 29.7 and 26.0 cm (total length), and the ultimate size based on Walford’s graph 76.0 and 64.5 cm in Gobindsagar Reservoir (Himachal Pradesh), and Harike Wetland (Punjab) respectively.

The paper presents the analysis of relationships between variations in Fulton′s condition coefficient (K) and the exponent n in the length-weight (L-W) relationship. When n < 3, K was observed to decrease with fish size; a reverse was true when n > 3. On the other hand, the condition coefficient K′ (Bagenal and Tesch 1978) remained constant and not related to fish size, regardless of n. The two coefficients were used to study condition of the Lake Miedwie pike (85 individuals) and perch (316 individuals) and to determine relationships between condition on the one hand and the fish length, weight, water temperature, and feeding intensity on the other. Four mathematical functions (linear, power, log, and exponential) were applied to study the relationships in each species. In addition, relationships between condition and water temperature and feeding intensity were explored by means of multiple regression. Condition of the two species studied was found to be similar to that reported earlier from water bodies of the former USSR, Węgorzewo Lake District, and the River Odra estuary.

The chub showed a peak in spawning in June. The weight and condition (K) at the same lengths and the length-weight regression (W=ɑLᵇ) coefficients of the sexes did not differ statistically for the same season, but they were slightly higher in females (except for b). Both sexes reached the maximum weight, K, and ɑ values in spring when the gonads were ripening. Those values decreased considerably in summer owing to spawning activity. The value of regression coefficient b was lowest in spring, and highest in summer (overall b was close to 3.0, except for females in spring).
