“…These observations are consistent with previous reports of the age structure (Mann, 1971;Allen and Wootton, 1982;O'Hara and Penczak, 1987;Wootton and Smith, 2000;Poizat et al, 2002;Wootton, 2007) and sex ratio (Kynard, 1978;Wootton, 1984;Mori, 1993;Arnold et al, 2003) of three-spined stickleback populations. Disproportionate mortality among males due to the energetic demands and risks associated with male parental investment has been suggested to account for the female bias (Chellappa et al, 1989;Arnold et al, 2003).…”

“…This resulted in fish with mean lengths in May in excess of those reported for one-year old sticklebacks in other UK populations (Mann, 1971;Allen and Wootton, 1982;O'Hara and Penczak, 1987) and with clear separation between the current (0+, 2008) and previous (1+, 2007) year classes. In July very few fish that could be apportioned to the preceding year class were caught in the R. Ray.…”

Body mass, fork length, RNA:DNA ratio, specific growth rate, and hepatic EROD activity and CYP1A expression, were measured in three-spined sticklebacks in the River Ray (south west England) at sites downstream of an urban waste water treatment works (WWTW) prior to, and following, remediation of the effluent with granular activated carbon (GAC) tertiary treatment.During the same two-year period fish were also sampled from a neighbouring reference river (R.Ock). The WWTW effluent elevated water temperatures and nutrient content in the R. Ray and rendered a direct comparison of fish populations in the two rivers untenable. Instead, the stability of population parameters within each river during matched pre-and post-remediation periods was compared. Stickleback populations in both rivers were annual but fish in the R. Ray spawned earlier and were larger than those in the R. Ock. In the R. Ray fish gained mass throughout the winter months whereas in the R. Ock growth was much reduced during this period. In fish from the R. Ray the somatic RNA:DNA ratio remained elevated during May-November after remediation, rather than declining as in the same period pre-remediation and as was the case for fish in the R. Ock during both periods. The specific growth rate of the first post-remediation generation of sticklebacks in the R. Ray was higher than that of the previous pre-remediation generation.Following remediation there was no decline in hepatic EROD activity or in the abundance of hepatic CYP1A transcripts in fish in the R. Ray suggesting that the primary route of exposure to contaminants for these fish was not via the water column, and that the change in performance of the fish post-remediation was not impeded by continued exposure to contaminants. Both EROD activity and CYP1A expression increased in fish in the R. Ock during the later stages of the study suggesting that the fish in this river were exposed to an unidentified contaminant episode. This may have been linked with the poorer performance of fish in the R. Ock during the post-remediation period. The improved performance of fish in the R. Ray suggest that there may be factors in good quality secondary treated sewage effluent which can adversely influence the performance of fish populations, directly or indirectly, and which can be removed by tertiary treatment.3

To eat or not to eat: egg-based assessment of paternity triggers fine-tuned decisions about filial cannibalism

et al. 2010

Filial cannibalism occurs in many animal species ranging from insects to mammals, and is especially well described in teleost fishes. Numerous causes may lead to this behaviour, e.g. certainty of paternity. However, the cues males use to assess their paternity often remain unknown. One possible way to differentiate between own and foreign offspring is by using egg cues. Nevertheless, in egg-laying species, evidence for this is still scarce. In this study, male three-spined sticklebacks (Gasterosteus aculeatus), a fish with paternal care in which sneaking as well as filial cannibalism is common, were allowed to care for manipulated nests that contained different percentages of own fertilized eggs. After 7 days, embryo survival was determined. Furthermore, brood-caring as well as aggressive behaviour was measured daily. Clutches containing a higher proportion of foreign eggs were more likely to be completely cannibalized than clutches containing a lower proportion of foreign eggs, particularly when the clutch was laid early in the breeding season. However, the behavioural observations revealed no influence of paternity. The results show that paternity triggers filial cannibalism in sticklebacks and that males are able to evaluate their paternity using egg cues alone.

Pattern of hyperphagia in immature three-spined sticklebacks after short-term food deprivation

Juvenile three-spined sticklebacks Gasterosteus aculeatus were fed live enchytraeid worms, and mean daily ad libitum consumption in the absence of periods of deprivation was 11·7% of initial body weight. Then, six groups of five replicate fish were subjected to 1, 3 and 6 days without food. Each period of deprivation was followed by 1 day of ad libitum feeding. The sequential order of deprivations differed between groups. Over the sequence of deprivations and re-feedings, mean cumulative consumption did not differ between groups. Mean daily consumption was 19·8% of initial body weight after a 1-day deprivation, 22·3% after 3 days and 19·5% after 6 days. However, consumption in the 24 h after a given length of deprivation also depended on the prior history of deprivation. Specific growth rate over the experiment did not differ between groups. The results provide evidence for an effective regulation of appetite in growing sticklebacks. 2000 The Fisheries Society of the British Isles
