Abstract:

The length-weight relationship and condition factor of two hundred and seventy-one samples of Protopterus annectens (Owen, 1839) from Orashi and Sombreiro Rivers were investigated. The length-weight relationship calculated for the species gave an average “b” value of 1.0943 which is an indication of negative allometric growth. The fish attained an average length of 44.7 cm and weight of 150.2 g. The Condition factor varied from 0.10 to 0.19 with a mean of 0.15±0.02. This result showed that the rivers provide nourishable environment for the well-being of the fish.Keywords: Length-weight relatio

Abstract:

Lepidosiren and Protopterus have a jaw-opening muscle which is topographically and functionally similar to the depressor mandibulae of salamanders. The similarity is so close that it poses the question whether the lepidosirenid jaw-opening system is homologous to that of tetrapods. New information presented here confirms that the muscle is absent in Neoceratodus forsteri, the living sister species of Lepidosiren and Protopterus, and paleontological evidence shows that the muscle was absent in phylogenetically primitive lungfishes. There are also developmental differences between the mandibular

Abstract:

Aspects of the biology of the African lungfish, Protopterus annectens (Owen, 1839) from Orashi and Sombreiro Rivers in Rivers State, Nigeria were investigated using routine biological approaches. Samples were collected between October 2012 and September 2013. The analysis of the stomach content showed that the fish from both rivers fed mainly on detritus, which accounted for 100% of the stomachs examined. Other food items included remains of higher plants, filamentous algae and diatoms. A sex ratio of 1:1 male: female was observed, although, females were more predominant than males during the

Abstract:

Protopterus dolloi Boulenger, 1900 is an obligate air-breather and exhibits ammoniotely (88% ammonia-N excretion, 12% urea-N excretion) under normal aquatic conditions, but tolerates 7 days of exposure to 30 mmol·L1 NH4Cl, a treatment fatal to most other fish. Internal N accumulation is minimal and the subsequent washout of ammonia-N and urea-N after return to control conditions is negligible, indicating that N excretion continues and (or) that N metabolism is markedly depressed. Exposure to 30 mmol·L1 NH4Cl in a closed system without aeration results in depressed urea-N excretion. The lungf

Abstract:

Lungfishes are the closest living relatives of the tetrapods, and the ear of recent lungfishes resembles the tetrapod ear more than the ear of ray-finned fishes and is therefore of interest for understanding the evolution of hearing in the early tetrapods. The water-to-land transition resulted in major changes in the tetrapod ear associated with the detection of air-borne sound pressure, as evidenced by the late and independent origins of tympanic ears in all of the major tetrapod groups. To investigate lungfish pressure and vibration detection, we measured the sensitivity and frequency respon
