In aquaculture, monitoring fish size and density is fundamental to improve management and profitability of fish farms. The aim of this study is to test whether horizontally aimed 200-kHz transducers are adequate to obtain fish size structure in open-

Horizontal applications of hydroacoustics are used to estimate the density and biomass of fish populations in shallow aquatic ecosystems. In order to calculate fish biomass and density, it is necessary to know the relationship between the biological

We constructed the food webs of six Mediterranean streams in order to determine ecological generalities derived from analysis of their structure and to explore stabilizing forces within these ecosystems. Fish, macroinvertebrates, primary producers an

A trophometric index (TMI) is proposed to estimate fish density, biomass and production in Mediterranean reservoirs. It consists of simple and integrated environmental variables such as the form index (IF = S/V ), the volume percentage of water with

Brown trout (Salmo trutta) population of a remote high mountain lake (Lake Redo, Pyrenees, 2240 m above sea level) were studied during autumn using hydroacoustic techniques. This acoustic technique was for the first time used on fish at such high alt
