VIS – A database on the distribution of fishes in inland and estuarine waters in Flanders, Belgium
The Research Institute for Nature and Forest (INBO) has been performing standardized fish stock assessments in Flanders, Belgium. This Flemish Fish Monitoring Network aims to assess fish populations in public waters at regular time intervals in both inland waters and estuaries. This monitoring was set up in support of the Water Framework Directive, the Habitat Directive, the Eel Regulation, the...

متن کاملDetermination of density and distribution of commercial fishes (Argyrops spinifer- Carangoides talamparoides – Saurida tumbil) in Persian Gulf waters (Bushehr Province)
This study was conducted to determine density and distribution of commercial fishes (Argyrops spinifer- Carangoindes talamparoides and Saurdia tumbil) by swept area method in Persian Gulf waters (Busher province). Sampling operation (27 hauls) was done by a trawler (Tabas class) with long 26 m and width 7.4 m in fishing season. Midwater trawl ned had a 72 m head rope and mesh sizes were 400 mm...

نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...
Spectra of particulate backscattering in natural waters.
Hyperspectral profiles of downwelling irradiance and upwelling radiance in natural waters (oligotrophic and mesotrophic) are combined with inverse radiative transfer to obtain high resolution spectra of the absorption coefficient (a) and the backscattering coefficient (b(b)) of the water and its constituents. The absorption coefficient at the mesotrophic station clearly shows spectral absorptio...
