“…Therefore, it is recommended to select proper sized females at the stage of spawn collection. This is of particular importance for such species as Atlantic cod (Folkvord and Otterå 1993), African catfish (Hecht and Appelbaum 1988), rainbow trout (Oncorhynchus mykiss) (Baras and Jobling 2002), largemouth bass (Micropterus salmoides) (DeAnglis et al 1980), walleye (Sander vitreus) (Loadman and Moodie 1986), European seabass (Dicentrarchus labrax) (Katavić et al 1989) and dorada (Baras et al 2000a).…”

Cannibalism is a common phenomenon that occurs in over 30 fish families. Most of the species are valuable objects of aquaculture and cannibalism is highly undesirable. Cannibalism is an aggressive behaviour, which can be caused by stress induced by various population and environmental factors and can occur in two main forms: early larval and late juvenile (or adult). Each of these forms can lead to severe losses of stock. Losses are caused not only by fish eating each other, but also by an increase in the number of infections (the result of body surface damage). It is important to understand the phenomenon of cannibalism in order to properly prevent, diagnose and reduce it. The main aim of this study was to present and examine some of the well-examined methods of cannibalism mitigation. Most of the methods consist of creating rearing conditions similar to natural conditions and to reduce stress. Moreover, because of large interspecies differences, similar methods can result in different effects depending on the species. Additional studies are needed to better understand the biology of each cultured species with particular emphasis on the impact of domestication, as well as to improve fish rearing conditions.

“…This is much earlier than in most other temperate species (e.g. pike Esox lucius; Giles et al, 1986;Bry et al, 1992; koi carp Cyprinus carpio, van Damme et al, 1989; sea bass Dicentrarchus labrax, Katavic et al, 1989;yellowtail Seriola quinqueradiata, Sakakura and Tsukamoto, 1996), but slightly later than in other percids (walleye Stizostedion vitreum : Cuff, 1977;Loadman et al, 1986) and percichtyids (striped bass M. saxatilis: Braid and Shell, 1981) at similar temperatures. Brabrand (1995) observed that perch could consume siblings tail first or head first.…”

The effect of stocking density (10, 31.6 and 100 larvae l À 1 ; three replicates per treatment) on the day-by-day dynamics of survival, growth and cannibalism was examined in sibling perch larvae reared from eyed-egg stage in 100-l cages (16L:8D, 20.0 F 0.5 jC, O 2 z 6.0 mg l À 1 ; feeding in excess with live Artemia nauplii during the photophase) during the first 3 weeks of exogenous feeding. Larvae unable to achieve the transition to exogenous feeding died in between 7 and 11 days post-hatch. Later, mortality from causes other than cannibalism never exceeded 1% day À 1 . Cannibalism did not start before days 10 -11 and first consisted in the incomplete ingestion of prey attacked tail first, exclusively. This type of cannibalism never caused losses higher than 2.0% of the initial stock, and ceased after days 16 -18. From days 12 -14 onwards, differential growth was apparent, and cannibals turned to complete cannibalism of small prey ingested head first, which caused greater losses (28 -53% of the stock). Increasing the stocking density did not compromise growth and decreased the overall impact of cannibalism through several complementary mechanisms: (i) a postponed emergence of cannibalism, (ii) a lower proportion of cannibals in the population, and (iii) probably a lower rate of cannibalism per capita as predation was complicated and less directed at high stocking density.

“…Increased ammonia concentrations due to death and decomposition of Artemia sp. nauplii could be minimized by increasing the water rennovation and more frequent cleaning of the experimental units (Katavic, et al, 1989;Catharin, 2003). In this study, higher survival rates were found between 1.7 and 5‰ salinities.…”
