“…Of the temperature variables, the best fit was found with water degree-days over 10°C. This temperature threshold has been found vital for the growth of age 0 pikeperch (Mooij et al 1994;Lappalainen et al 2000;Kjellman et al 2001), but the corresponding thresholds have not been studied for older pikeperch. An earlier observation of large numbers of empty stomachs of pikeperch during the spawning season or immediately after it (Kangur 2000) suggests that the onset of the growing season for mature pikeperch is probably after spawning.…”

“…In two earlier studies the model (1) was found to give consistent surface water temperatures (Kjellman et al 2001(Kjellman et al , 2003. First, the model was fitted for the two years of 2003 and 2004, and then the corresponding coefficients p1 and p2 were used to evaluate daily water temperature based on air temperature for the two independent years 2000 and 2001.…”

“…Thus, a significance level of 0.05 is required to allow a variable into the model, and a significance level of 0.05 is required for a variable to stay in the model. Two temperature thresholds of 0 or 10°C were analysed to select the best model, because for the juveniles, the threshold value of 10°C has been found to be important (Mooij et al 1994;Lappalainen et al 2000;Kjellman et al 2001), whereas the 0°C threshold was chosen to Year-class estimation…”

Pikeperch (Sander lucioperca), the studied species, is the most important amongst freshwater fish species, commercially, in the brackish Baltic Sea. We studied the effects of water temperature on three aspects of pikeperch growth in Haminanlahti bay, Finland. First, annual length increments were related to age and temperature using a non-linear growth model. Since length increments were based on backcalculated lengths, i.e. repeated measurements, the first order autoregressive covariance structure was used. The model showed that when temperature increased annual length increments also increased, whereas increased age reduced annual length increments. In the modelling, the best fit was found with water degree-days over 10°C. Second, the onset of growth of pikeperch in spring had a positive relationship with water temperature and a negative one with the length of pikeperch. The latter finding suggests that smaller, non-mature pikeperch starts to grow earlier than larger, mature pikeperch. Third, the year-class strength was positively correlated with water degree-days, and the year-class strength negatively affected annual length increments. This indicates that within a strong year-class subsequent growth is reduced more that within a weak year-class, suggesting density-dependent growth.

“…Year-class strength of the majority of coastal fish species is strongly dependent on reproductive success and survival during the first year of life (Kjellman et al, 2000(Kjellman et al, , 2003Houde, 1997). The quality of their recruitment and feeding areas are therefore of fundamental importance for the structure of the adult commercially utilised stocks.…”

An insight is made into the main processes that occur in fish during endogenous feeding period. The ways in which yolk absorption rate can be measured are evaluated. Essential amino acids and polyunsaturated fatty acids are preferentially retained for incorporation into body tissue. Profound physiological and anatomical changes in yolk and a sequence of slow, fast, and a second period of slow absorption occur during the endogenous feeding period. Attempts to quantify the ontogenetic sequence are reviewed. Various methods of body size assessment are compared, and sources of bias in individual and population growth estimates are discussed. Several calorimetric methods are compared of which direct calorimetry using an oxygen bomb is the reference method. An advanced elemental analysis (CHNS) is a reliable technique that is adequate for early stages. Indices of growth potential are reviewed including a comparison of different measures, models and approaches used to estimate growth. Changes in body hydration, caloric value, content of lipids, protein, free amino acids (FAA) and minerals, and in content of RNA and DNA occur in early ontogeny. Ways to quantify metabolic rate are identified. Mean relative respiration rate of initial egg before activation is very low, about 20 mm 3 g À1 h À1 . Ontogenetic sequence in absolute metabolic rate of fish embryos and yolk-feeding larvae involves an increase through hatching to a peak at the time of first feeding ability, and a decrease under starvation. Models predicting the relationship between oxygen consumption and age in yolk-feeding fish are reviewed. Sequence of metabolic fuels begins with use of small molecules as carbohydrates, soon switched to FAA. Later lipids are progressively used, they provide energy for swimming activity. After yolk depletion body protein-bound amino acids are mobilised. In this review I focused on the major environmental variables as temperature, oxygen, salinity, pH, toxic xenobiotics, light, UV radiation, magnetic field and substrate, along with intrinsic factors as egg or body size, sex and genetic factors. A question was posed on how the extrinsic and intrinsic factors determine yolk absorption, growth and metabolic rates in yolk-feeding fish. Special attention is devoted to fish body size attained exclusively on yolk. A considerable variety of body size responses to temperature was found, for which several explanations are forwarded. Methodological progress made recently is characterised and the most conspicious advances in understanding of fish early life history are highlighted. Information derived from these studies can be used in management of fish populations in the field and to optimise activities in aquaculture.
