“…A possible explanation for the high reproductive allocation of small males is the existence of different male mating tactics, although no available records indicate alternative male reproductive tactics in the convict cichlid. However, some African cichlids exhibit alternative male reproductive tactics and elevated GSI values are observed in small nonparental males (Sato et al 2004;Katoh et al 2005;Ota and Kohda 2006). Unfortunately, because of the low water visibility in the Haebaru Reservoir, visual observation of convict cichlid reproductive behaviors is impossible in this system.…”

Life history parameters associated with reproductive biology, age, and growth of the convict cichlid (also known as the zebra cichlid) Amatitlania nigrofasciata, which was introduced into the Haebaru Reservoir on Okinawa-jima Island, were estimated using 437 specimens that ranged from 13.7 to 82.9 mm standard length (SL). Lengths of females at first maturity (SL) and 50% maturity (L 50 ) were estimated to be 32.2 and 37.3 mm SL, respectively. The spawning period continued throughout the year, with a peak spawning cycle from March to May 2006-2007. Observations of postovulatory follicles and tertiary yolk stage oocytes indicate that convict cichlids spawn multiple times within a year. Female cichlids that hatched during the peak spawning seasons matured after October of the same year. Batch fecundity of females (32.2-61.2 mm SL) ranged from 65 to 345 (mean ± SD=155±63). Opaque zones along the outer margins of otoliths formed annually. The maximum age of male and female cichlids was 3 years. The von Bertalanffy growth formulae (VBGF) were expressed as L t ¼ 57:4 1 À e À0:78 tþ0:91 ð Þ À Á for females and L t ¼ 69:5 1 À e À1:07 tþ0:24 ð Þ

Cooperative Breeding in the Lake Tanganyika Cichlid Julidochromis ornatus

Cooperative breeding has been described for several cichlids from the genus Julidochromis (Perciformes: Cichlidae) under laboratory conditions, but field evidence is scarce. Here we describe the breeding system of the cichlid Julidochromis ornatus (Boulenger) in Lake Tanganyika (Zambia). Groups defended a breeding shelter under a large flat stone. Smaller group members stayed and fed under or close to the stone, actively guarded by the larger group members. Six out of 28 groups were newly established by breeders, joined by subordinates from a large pool of independent fish (comprising 50-70% of the total population), and four groups were seen to dissolve during a total of 77 observation days. Breeding groups consisted of a large breeding male and female with zero to five smaller subordinates (average 2). Larger breeders and subordinates were found in larger groups. All group members participated in territory defence and -maintenance, but the breeders were only present at the shelter 48% of the time, in contrast to the subordinates which guarded the breeding shelter 94% of the time. Smaller group members showed submissive behaviours to larger group members. We conclude subordinates in J. ornatus are helpers, but we did not find evidence that helpers increased the group's current reproductive success. Personal observations combined with a literature review revealed at least 19 species of Lake Tanganyika cichlids show evidence of cooperative breeding, entirely confined to the substrate breeding tribe of the Lamprologini (24% of 80 species in total): 2 Chalinochromis spp., 5 Julidochromis spp., 12 Neolamprologus spp. More effort should be put into detecting cooperative breeding in American and Asian substrate breeding cichlid species.

“…The transitional vertebrae both species are the same. Such similarity might indicate a similarity in the general structure of the vertebral column that adapt to feeding habits (Oso et al, 2006) or reproductive-tactic-specific variation (Bruton and Gophen, 1992;Ota and Kohda, 2006;Fitzpatrick et al, 2007) used by those different cichlid species.…”

This paper presents the results of a comparative study of the vertebral column regionalization of Coptodon zillii andOreochromis aureus of the fish family Cichlidae. Osteological features that may prove valuable for taxonomic indications are defined, and on the basis of the material handled, their use to separate the two cichlid species. The morphological characteristics of the vertebral column of C. zillii and O. aureus allowed the separation of this bony structure into five morphologically distinct regions and the features of their specified vertebral shape. This regionalization is more complex than the classical division in truncal and caudal parts only. The vertebral length and height express a morphotype that may be linked with the cichlid mode of swimming.
