Aquaculture is globally the fastest growing sector of agriculture that needs to be sus- tainable and must also meet bioeconomic demands. In principle, aquaponics, the combination of aquaculture and horticulture within a single recirculating aquaponic

After temperature-induced puberty at 12 degrees C for 12 weeks, the progression of gametogenesis in maturing pikeperch (Sander lucioperca) was studied at 12 degrees C, 14 degrees C, 16 degrees C, and 18 degrees C, compared with a control group reared

In recirculating rearing systems of aquatic food organisms, humic substances (HSs) accumulate along with toxic nitrogen species (nitrite, unionized ammonia). The aim of the present study was to find out whether or not HSs have the capability to modif

The present study investigated the effect of varying dietary protein-to-lipid ratios (P/L) on growth performance and body composition of pike perch (Sander lucioperca) fingerlings with an initial body weight of 1.35–1.40 g. Triplicate groups were r

Triplicate groups of pike perch (Sander lucioperca) juveniles were fed six experimental diets containing protein levels varying from 263 to 619 g kg−1 dry matter (d.m.) for 56 days. Dietary protein was supplied by graded amounts of fish meal (with

To evaluate isolated pea protein as feed ingredient for tilapia (Oreochromis niloticus) juveniles, triplicate groups were fed with four isonitrogenous [crude protein: 421.1–427.5 g kg−1 in dry matter (d.m.)] and isoenergetic (gross energy: 20.46

To assess the effect of dietary composition on growth performance and body composition of pike perch (Sander lucioperca), fingerlings with an initial body weight of 1.36 g (just trained to accept formulated feed) were fed three experimental diets in

Pike perch (Sander lucioperca) has been identified as specie destined to diverse European inland aquaculture, but knowledge on the nutritional requirements is weak. Therefore, we investigated the effect of varying dietary fatty acid (FA) profile by p

Summary Zander (Sander lucioperca) is one of the most important fish species in the German inland fishery. As a pelagic predator, zander is able to regulate populations of small cyprinids and perch and is therefore used in ‘top-down’ projects to
