  • Black Flounder) Family: Pleuronectidae
    9 Pātiki Mohoao (Black flounder) Family: Pleuronectidae Species: Rhombosolea retiaria The black flounder (Figure 69), pātiki mohoao (Rhombosolea retiaria), is the only member of the flatfish family, or Pleuronectidae, that is a truly freshwater species. Other members of the family, such as the yellow-belly flounder (Rhombosolea leporina), occasionally wander into the lower reaches of rivers, but do not usually stay there. As their name implies, the flatfishes are indeed flat, and have adopted a habit of laying on their sides down on the substrate. Both eyes are on their dorsal or upper side to improve their field of view. Because of their shape, flounders are unlikely to be confused with other fish species except other flatfishes. The black flounder is easily distinguished from other flatfishes by its colouration; the top of the fish is usually dark-coloured with numerous, obvious brick-red spots. Flounders can grow to about 450 mm in length, although 200–300 mm fish are most common. Figure 1: (Top) The adult black flounder (Rhombosolea retiaria); and (Bottom) Juvenile black flounder, c. 10 mm in length. (Sources: [Top] Bob McDowall; [Bottom] Roper [1979] in Eldon & Smith [1986]). The black flounder is found throughout Aotearoa-NZ and is unique to this country. They are primarily a coastal species, although they can penetrate well inland if the river gradient is not too steep and specimens have been recorded more than 100 km inland in some river systems. Black flounder are a carnivorous species and probably eat a variety of bottom dwelling insects and molluscs. They are also known to feed on whitebait during the spring migration.

Assessment of key reproductive markers after hormonal induction of spawning, using gonadotrophin-releasing hormone in female yellow belly flounder (Rhombosolea leporine): A thesis submitted in partial fulfilment of the requirements for the degree of Master of Science in biological sciences at The University of Waikato by KENT JEFFRIES Year of submission 2019 1 Abstract Yellow belly flounder (YBF) (Rhombosolea leporina) are of interest to the New Zealand aquaculture industry as a novel culture species. This is due to their high commercial value and low trophic feeding level. However, when held in captive settings, YBF are observed to undergo reproductive failure. GnRHa has been used as a spawning inducing agent within many cultured fish species. Flounder gonadotrophin levels were traced after induction and oocyte development was histologically assessed. At pituitary level it was seen that the GnRHa induction resulted in increased follicle stimulating hormone (FSH) levels.

  • Complete Mitochondrial Genome Sequences of Three Rhombosoleid
    Wang et al. Zoological Studies 2014, 53:80 http://www.zoologicalstudies.com/content/53/1/80 RESEARCH Open Access Complete mitochondrial genome sequences of three rhombosoleid fishes and comparative analyses with other flatfishes (Pleuronectiformes) Shu-Ying Wang, Wei Shi, Xian-Guang Miao and Xiao-Yu Kong* Abstract Background: Peltorhamphus novaezeelandiae, Colistium nudipinnis, and Pelotretis flavilatus belong to the family Rhombosoleidae of Pleuronectiformes. Their high phenotypic similarity has provoked great differences in the number and nomenclature of the taxa that depend primarily on morphological features. These facts have made it necessary to develop molecular markers for taxonomy and phylogenetic studies. In this study, the complete mitogenomes (mtDNA) of the three rhombosoleid fishes were determined for the comparative studies and potential development of molecular markers in the future. Results: The lengths of the complete mitogenome of the three flatfishes are 16,889, 16,588, and 16,937 bp in the order mentioned above. The difference of lengths mainly results from the presence of tandem repeats at the 3′-end with variations of motif length and copy number in the control regions (CR). The gene content and arrangement is identical to that of the typical teleostean mtDNA. Two large intergenic spacers of 28 and 18 bp were found in P. flavilatus mtDNA. The genes are highly conserved except for the sizes of ND1 (which is 28 bp shorter than the two others), ND5 (13 bp longer), and tRNAGlu (5 bp longer) in P. flavilatus mtDNA. The symbolic structures of the CRs are observed as in other fishes, including ETAS, CSB-F, E, D, C, B, A, G-BOX, pyrimidine tract, and CSB2, 3.
