The study estimated population parameters of four leading commercial fish species Awach Kibuon River in Lake Victoria Basin, Kenya to inform management interventions for sustainability. Length data were collected monthly from January December 2020 and length-frequency analysis conducted FiSAT II software utilizing ELEFAN I Routines. Exploitation rates (E = 0.63) Protopterus aethiopicus (Heckel,...

F1 offspring of the African cichlid Pseudocrenilabrus multicolor victoriae Seegers, 1990 from swamp (low oxygen) and lake (high oxygen) origin were raised under normoxia and submitted to hypoxia acclimation (0.8 ± 0.4 mg L–1) and normoxia acclimation (7.4 ± 0.3 mg L–1) for 4 weeks. Haematocrit and lactate dehydrogenase (LDH) specific activities in the liver, white skeletal muscle, heart, and br...

Dissolved oxygen (DO) can be a strong predictor of intraspecific variation in morphology and physiology in fishes. In the African cichlid Pseudocrenilabrus multicolor victoriae Seegers, 1990, fish reared under low DO develop larger gills, deeper bodies, and larger, wider heads than full siblings reared under high DO, which could influence swim performance. In this study, we compared critical sw...

Lamellocytes are specialized larval blood cells of Drosophila that carry out encapsulation of metazoan pathogens such as parasitoid wasps. Large virus-like particles (VLPs) from two closely related virulent parasitoid wasp species, Leptopilina heterotoma and Leptopilina victoriae, suppress the host encapsulation response by promoting lysis of lamellocytes. The molecular basis of VLP-lamellocyte...

A preliminary experimental study was carried out to examine the ability of a chemically modified Acacia spp. to resist biodegradation. The modifications of Acacia mangium and Acacia hybrid were carried out by propionic anhydride and succinic anhydride in the presence of sodium formate as a catalyst. The treated samples were found resistant to microbial attack, while the untreated ones were dama...

During a review of Australian Germalus Stål, types of all species recorded from Australia, as well as of the type species G. kinbergi Stål, originally described from Mauritius Island, were examined and illustrated to redefine and redescribe the genus as well as all the included species. As a result of this, the following synonymies have become necessary: G. humeralis Distant as junior synonym o...
