“…Given the importance of L. guttatus for fi sheries and aquaculture, it is necessary to improve our knowledge about its parasite diversity and infection levels on wild fi sh populations. In fi sh parasite ecology, there has been some evidence for an increase in parasite diversity with host size (Lo et al, 1998); however, in many cases the correlation between those factors may be weak and non-signifi cant (Poulin, 2000). Other ecological processes may occur at spatial scale.…”

SummaryThe helminth communities of L. guttatus from Mazatlan Bay (MB) and Banderas Bay (BB), on the Pacifi c coast of Mexico, were studied during two consecutive years. A total of 536 fi sh were collected and 19 parasite taxa registered (six digeneans, two cestodes, nine nematodes, and two monogeneans). Infection levels of common helminth species (Helicometrina nimia, Siphodera vinaledwardsii, Tetraphyllidea gen. sp., Pseudoterranova sp., Ancyrocephalidae gen. sp. and Microcotyloides incisa) as well as the infracommunity indices varied signifi cantly between MB and BB, and among dry and rainy seasons; however, no clear seasonal patterns were observed. Pseudoterranova larvae appeared frequently in MB, possibly because of the presence of the California sea lion in this locality. Similarity analysis did not show a clear separation of parasite species composition between both localities, which suggest that fi sh samples came from a single population of L. guttatus.

“…Additional research with histological and immunological investigation is therefore required. Lo et al (1998) reported a positive relationship between host size and common endoparasite abundance in the digestive system of fish. The authors suggested that the larger fish consume more food and are more liable to infection.…”

“…Johnson et al (2005), for example, estimated a positive relationship between wing feather size and wing louse body size. Studies in fish have reported that the size of host fish has a strong impact on the abundance and richness of common ectoparasites (Poulin and Rohde, 1997;Lo et al, 1998;Cable and van Oosterhout, 2007). These results led to controversial questions such as whether endoparasites generally relate to the size of their environments or their hosts, and whether differences in body and/or organ size of the host partly explains variation between animals with regard to worm burden or faecal egg counts (FECs) in small ruminants.…”

The relationship among parasitological parameters, abomasal size and body size measurements was investigated in lambs following an experimental infection with Haemonchus contortus. In total, 100 lambs from five different genotypes (German Merino (GM), Texel 3 GM, Suffolk 3 GM, German Blackhead Mutton 3 GM and Ile de France 3 GM) were experimentally infected with 5000 infective third stage larvae of H. contortus at the time of weaning at 12 weeks of age. Four and six weeks after infection, individual faecal samples were collected for estimation of faecal egg counts (FECs). Furthermore, wither height, shoulder width, heart girth, loin girth and body length were taken at 18 weeks of life. Lambs were slaughtered and necropsied 7 weeks post-infection, and worm counts, abomasal volume and surface area were determined. Positive correlations were found between different body size parameters, body weight and abomasal sizes. FEC and worm counts were not significantly correlated either with body size parameters or with abomasal size. The mean worm burden was higher in GM than in crossbred lambs. There was no significant difference in abomasal size between GM and crossbred lambs. The results suggest that the variations between animals in worm burden following an experimental infection with H. contortus (worm resistance) are not influenced by body size parameters or abomasal sizes. Therefore, other factors, including genetic-based differences in resistance, must cause these findings between and within breeds.

“…As regards the relationship between the level of Dactylogyrus infection and the size of host fish, there have been several researches indicating that the abundance of Dactylogyrus is often higher on older fish than younger fish (Loo et al, 1998;Ozer and Ozturk, 2005;Ozturk and Altunel, 2006). Ozturk and Altunel (2006) Ozturk and Altunel (2006) reported that the abundance of D. difformis infection was higher in younger fish than in older fish.…”
