The fecundity of a local, stationary population of vimba bream Vimba vimba (L.) from Lake Ostrowieckie (Oder River drainage area, northwest Poland) was analyzed. The number of eggs in the ovaries was determined by the weight method. The individual absolute fecundity of vimba bream ranged from 9,560 to 157,000 eggs for females measuring from 19.2 to 34.0 cm and weighing from 121 to 693 g. Fecundity varied in the designated size classes from 21 thousand eggs for individuals below 22.0 cm to 104 thousand eggs for the largest ones (longer than 30.1 cm). The average fecundity in the youngest group of females (4+) was 25.6 thousand eggs, while that in the oldest group (9+) was 120.1 thousand eggs. Correlation analysis of absolute fish fecundity versus selected biometric parameters showed a significant dependence.

The aim of the study was to determine the food preferences of the black cormorant and to assess fisheries losses in Włocławski Reservoir. Twenty fish species were identified in the cormorant diet. The dominant species were ruff and perch (29.4% and 24.4 % of the weight share, respectively). Roach (11.9%) and Prussian carp (10.9%) were also important components of the cormorant diet. The share of invasive species from Gobiidae family was negligible (0.2%). Among the fish species important to commercial and recreational fisheries management, the most numerous in the cormorant diet were: ide (10 t; 2.7% of the weight share), pikeperch (8.6 t; 2.3%), asp (6.3 t; 1.79%), and pike (4.9 t; 1.3%). The fish biomass consumed by cormorants was a mean of 372.8 t annually, which is 46.6 kg per ha (range of 44.6 to 49.6 kg per ha). The analysis of fisheries losses in 2009 was estimated at 980,000 PLN.

The aim of the present study was to verify the feasibility of using live Artemia salina nauplii embedded with fluorochromes for the mass marking of pike Esox lucius (L.) larvae. In the experiment, pike larvae 6 days post hatch were fed ad libitum with nauplii dyed with 600 ppm tetracycline hydrochloride (TC) or 200 ppm alizarin red S (ARS) for 3 or 6 days. The highest percentage of marked fish (100%) and the best quality of this marking was found in the groups fed A. salina stained with TC for either 3 or 6 days. In groups fed A. salina stained with ARS for 3 or 6 days exhibited a lower percentage of marked fish (ranging from 76.7–88.3%). No significant differences between experimental groups were noted regarding survival rate, final body weight and length of the reared pike larvae.

The paper presents review of experimental triploidization trials in percid fishes, important for European aquaculture due to improve and diversification of fish production. The triploidization lead to obtain individuals with three sets of homologous chromosomes (3n) theoretically sterile andshowing a faster growth rate compare to the normal diploid fish. Triploidization in aquaculture isusually performed with the use of thermal/pressure and chemical shocks. Parameters of environmental shocks are species specific and it is extremely important to optimize the exact conditions for procedure. In percids the efficiency of the pressure and thermal shocks is varied, and the survival rate of triploids relatively low. However the production of triploid percids stocks using a pressure shock, can be adapted widespread in the future in the fishery practice

Macroscopic and microscopic changes which occur during the annual ovarian cycle of vimba females from the Drawieński National Park (DNP) were studied. The study was carried out in 1997-1998 using 146 fish with an average body length (longitudo corporis) of 24.2 cm and an average body weight of 274.9 g.No abnormalities or pathological changes in the ovaries of the investigated fish were detected. The histological picture showed the clear asynchronicity of oocyte maturation. The following ovary maturity stages, characteristic for portion spawners, were distinguished: IV₂; V₂; IV₃; V₃. A relatively short post-spawning stage was also identified (VI/II). It was confirmed that in vimba from the Drawieński National Park (DNP) the longest the maturity stage is III, which starts in October and finishes in March or April of the next year.
