  - Year 2022

  Acoustic techniques are used in the estimation of the abundance of Baltic herring. Investigations of the relationship between the Baltic herring individual target strength TS and the total fish length L, significant in the acoustic assessment, demonstrated its de-pendence on the study area location. It motivated the detailed analysis of the relationship between herring from the southern Baltic ICES Subdivisions 24, 25, and 26,...

  Effective management of Baltic clupeids, which are valuable commercially and ecologically,requires the biomass control. The acoustical techniques are recognized as effective in fishstock assessment. The study of Baltic herring and sprat individual backscatteringcharacteristics is required for the accurate biomass estimation using acoustical techniques.The previous measurements demonstrated significant...

  Reliable TS(L) relationship is required to improve acoustic algorithms of abundanceestimation of Baltic herring. The relationships, empirically obtained in different parts of theBaltic Sea, produce up to 8 dB – difference in the herring TS. In order to develop an accurateTS(L) relationship, it is important to analyze factors controlling the TS variability. Thepossible impact of the regional difference...

  Proces koagulacji przy pomocy soli żelaza stosowany jest do usuwania z wód poprocesowych przemysłu spożywczego zanieczyszczeń tłuszczowych i białkowych. Tak uzyskany osad pokoagulacyjny może być dodawany do produkcji rybnych hydrolizatów białkowych. Wytwarzano hydrolizaty białkowe ze szprota z dodatkiem osadów pokoagulacyjnych z przemysłu rybnego. Zmodyfikowano metodę wytwarzania rybnych hydrolizatów białkowych przez zmianę kwasu...
