Hematology analysis is a one of the basic tools used to evaluate health/welfare of fish. It is commonly used in scientific studies to assess the influence of various abiotic and biotic factors on fish. Its big advantage is a low cost and no need of sophisticated laboratory equipment. On the other hand, some stages of hematology analysis require kno...

Hematological analysis is used, among others, to assess fish health and welfare. The routinely analyzed hematological parameters include hematocrit, i.e. the ratio of the volume of erythrocytes to the volume of whole blood. In the case of fish blood, the most common method of hematocrit determination is the microhematocrit method, which is based on...

Analiza hematologiczna wykorzystywana jest m.in. do oceny stanu zdrowia i dobrostanu ryb, służy także do określania wpływu różnorodnych czynników środowiskowych na ich organizmy podczas prowadzenia badań naukowych. Obejmuje parametry czerwonokrwinkowe i białokrwinkowe. Do najczęściej analizowanych parametrów czerwonokrwinkowych należy hematokryt, c...

A haematological analysis is commonly used in studies concerning fish, e.g. to evaluate the influence of various environmental factors on the physiological state of a population. Furthermore, a manual haematology is still used for conducting fish blood analyses. The aim of the current study was to determine how long after the procedure of blood col...

Wrotki (Rotifera) są zwierzętami powszechnie występującymi w stawach rybnych. Niniejsze badania miały na celu porównanie składu gatunkowego i biomasy wrotków występujących w stawie typu karpiowego, w którym prowadzono hodowlę ekstensywną (Gołysz Wielki), ze składem gatunkowym i biomasą wrotków obecnych w stawie użytkowanym intensywnie (Wyszni III)....

The aim of the current study was to assess the influence of embryonic exposure to cadmium on basic and derived erythrocyte indices, the morphology and morphometric properties of erythrocytes, as well as erythrocyte spectrin distribution in newly hatched Gallus gallus domesticus chicks. The eggs were injected with cadmium (Cd) at a dose of 2 µg, 4 µ...

Fish production can generate high amounts of wastewater containing compounds such as suspended solids, nitrogen and phosphorus. On the other hand, fish ponds provide a range of ecological functions including biocenotic, physiocenotic, hydrological and microclimatic functions as well as landscape shaping. The aim of this study was to determine the t...

The effects of herbicide Roundup (based on glyphosate) on the embryonic development, survival and hatching of common carp (Cyprinus carpio L.) larvae and alteration in foxr1 and hsp70 gene expression were determined. The eggs (obtained from 6 females) were fertilised and incubated in water containing 0; 1 or 10 μl L⁻¹ of Roundup formulation. During...

The results of observations of intensive sturgeon production integrated with an extensive earthen fish pond are described. The main objective of the study was to show how technological modifications applied to enhance nitrogen assimilation in ponds and nutrient retention in aquaculture products influenced fish production. Each of two integrated sys...
