“…Fish diet was studied by stomach sampling (see Giles, 1980) large specimens (> I5 cm) total length) of fyke-netted bream, tench, perch and roach during the period May-July in 1986 and 1987, from both St Peters and Main Lake. Stomach-sampling was used successfully on tench by Petridis & O'Hara (1988). Fyke netting was used successfully in a study of the diet of tench by O'Maoileidigh & Bracken ( 1 989).…”

The abundance of benthic macroinvertebrate taxa and the relative abundance of zooplankton taxa were compared with the diet of bream, tench. perch and roach from two gravel pit lakes during May-July 1986 and 1987. Significant food preferences were demonstrated between species and between lakes. Chironomid pupae dominated the macroinvertebrate diet of perch, roach, ate predominantly either Spirogyra sp. (St Peters Lake) or Daphniu hyalina (Main Lake).The Main Lake, bream fed largely upon chironomid larvae and the bivalve Sphuerium but in St Peters Lake they positively selected a variety of less abundant benthic invertebrate taxa. Bream switched from benthos to zooplankton in the Main Lake in 1986. Tench ate large numbers of Aselhs and showed positive selection of various macroinvertebrate prey in St Peters but ate D.hjulim in Main Lake. Tropic overlap for chironomids and other macroinvertebrate prey was demonstrated between perch, bream and tench, and potentially with wildfowl which used the gravel pits for breeding and wintering.

“…Due to limited personnel, electrofishing was performed at 09.00-10.00 hours and seine-netting at 12.00-13.00 hours. After capture, the fish were held in keep-nets, each fish was then anaesthetized (MS 222) in a small tank, its stomach flushed (Petridis & O'Hara, 1988) and the contents preserved in 10% formalin solution. Weights and lengths were recorded to the nearest gramme and millimetre, respectively.…”

Ecological studies were carried out in shallow experimental sites in the Lancaster Canal to evaluate potential interactions between grass carp and feeding habits of tench.Grass carp. through moderate weed consumption, produced better conditions for the exploitation of benthic organisms by the benthophagous tench. because tench (>35 cm fork length) were able to search for food in the open areas created. This also enabled the fish to make use of zooplankton, mainly the large species Eurycercus laniellarus whose restricted phytophilic habitat made it vulnerable to predation. Epibenthic animals, in particular gastropods and Asellus ciquaricus. suffered principally from the predation. which caused severe reduction of them in the site totally depleted of vegetation. In this site, tench utilized a diet in which red chironomids were the dominant prey group together with a large amount of fine detritus.It is suggested that a moderate control of vegetation in temperate climates, using the grass carp as the biological agent, could be a satisfactory management technique for the improvement of aquatic habitats.

“…Neither stomach fiushing alone nor stomach flushing in combination with unique marking was found to have a significant effect on wild brown trout condition, supporting the findings of Strange &Kennedy (1981) andO'Farrell &McCarthy (1983). Similarly, condition of tench was unaffected by stomach flushing (Petridis & O'Hara 1988).…”
