This study examined the length-weight relationship and condition factor of Hydrocynus forskahlii (Cuvier, 1819) in River Yobe, Northeast, Nigeria. A total 350 fish species were collected from commercial fishermen at four landing sites (Gogaram, Dogona, Bize, Azbak) within area between June to November 2020. The morphometric meristic characteristics could be attributed environmental variations (...

Ramsar site designation is an acknowledgment of a wetland’s importance. In this study, we conducted biodiversity survey around Natuna to examine its eligibility as the next in Indonesia. This was through sampling for biological resources, using either transect, trapping, or visual observation. We surveyed 32 stations endangered and vulnerable fish, water birds, wetland-dependent species. Sample...

We have investigated the morphological effects of a genetic locus, Pgm1-t, that affects the expression of a phosphoglucomutase locus (Pgm1) in liver of rainbow trout (Salmo gairdneri). We have previously shown that embryos with liver Pgm1 expression hatch earlier than those without liver Pgm1 expression. We predicted that this difference in developmental rate should cause a reduction in meristi...

Management and recovery of endangered sawfishes are challenged by the un certainty of species determination. Frequently, dried rostra (saws) are the only material available to represent an historical occurrence, yet traditional methods of species identification of datadeficient rostra (rostral tooth counts) are unreliable. We evaluated the utility of morphometric characters for the identificati...

Aim: The study aimed to investigate the morphometric and meristic measurements, length-weight relationship relative condition factor of Odonus niger landed along coastal Karnataka. Methodology: (Kn) O. was studied for a period eight months from August 2019 March 2020. different characters were subjected statistical analysis. analyzed both sexes (female male) combined data. Monthly size group. R...

Information on the character of stingless bee nest entrance (Hymenoptera: Apidae: Meliponinae) as a characteristic for identifying species has never been carried out in depth. The purpose this study was to determine morphological characteristics that differentiate between found Belaban Resort conservation area, Bukit Baka Raya National Park. research conducted March, 16–26 2022. method used cru...
