Growth Determination of Selected Fish Species in River Hadejia, Jigawa State, Nigeria
The work was designed to investigate the various ages of selected species of fishes in River Hadejia with the use of opercula and scales. The growth marks were laid annually. The growth rate did not exhibit Rosa Lees phenomenon. The asymptotic length Loo had higher values in the males than the females except in Tilapia Zilli from site B. K(rate at which Loo is approached) and to (time at which the fish would be zero sized) did not show any consistent pattern of difference between the sexes. Growth performance index (d) was similar for the different species and sexes in all the sites, S.D = 0.103. The places show the growth marks on the opercula bones and scales of some selected fishes. Keywords: - Growth, Opercula, Scales, Rive
Analysis of Water Pollution in Gumel Local Government Area, Jigawa State, Nigeria
Pollution has always been an emotive topic irrespective of whether it occurs in the air, on land or at sea. In the later help of this century much attention has been drawn to water pollution caused by human activities and industrial revolution which experience local levels of high pollution quite unimaginable by present standard. This pollution has passed great risk to the health and immediate surroundings of those involved. It impact is further aggravated by the physical zoning of industrial waste discharge regulation leading to complex problems of water pollution. The conditions characterize the existence of substance in environment in quantities which can be deteriment to the well being of plants and animal
Alkaline Phosphatase (ALP) Activity in Selected Tissues & Organs of Clarias gariepinus Exposed to Different Levels of Paraquat
Analyzing the activities of alkaline phosphatase (ALP) in tissues can help detect tissue damage cause by toxicants such as paraquat,The activities of alkaline phosphatase (ALP) in some tissues and organs of Clarias gariepinus exposed to various levels of paraquat (2, 4, 6 and 8ppm) were studied for a period of thirty (30) days. The tissues and organs investigated include blood plasma, kidney, liver, gills and muscle. Results showed changes in ALP activity in the treatment group as compared to the control group except in the muscle and plasma where there were no significant changes. ALP activity was highest in the kidney in the control group (511.25+ 291.76 IU/L) while the lowest level of enzyme activity in the control group was observed in the muscle (1146.67+ 173.52 IU/L). Peak enzyme activity in the kidney was observed at 4ppm of paraquat. This later declined at higher treatment concentrations. There was no significant increase in ALP activity in the liver and gills at lower paraquat concentrations but a significant spike in enzyme activity was observed at 8ppm. Analyzing the activities of ALP in tissues can help detect tissue damage cause by toxicants such as paraquat. It can consequently be inferred that ALP activity can be used as a reliable biomarker for diseased condition in the kidney, liver and gills but not the plasma or muscle of Clarias gariepinus. Keywords: Alkaline phosphatase, pollution, Clarias garienpu
Analysis of some Aspects of Biology on Selected Fish species in River Hadejia, Jigawa State Nigeria
Analysis of some aspect of biology on selected species in River Hadejia, was carried out by analyzing the following, food and feeding habits using two method which are frequency of occurrence and dominant methods, forage to carnivore ratio,( F/C) was also estimated, water analysis was carried out purposely to find the food-fit in the body of water. The forage to carnivore ratio was estimated to be 3:1. while table 1-3 summaries the food items of Tilapia zill Orechromis niloticus and sarotherodon galilaeus.

Investigation of aspects of reproductive cycles of some selected fish species in River Hadejia, Jigawa State, Nigeria.
This work aims to analyse some aspects of reproductive cycles of some selected fish species in River Hadejia was carried out from July 2012 at June 2013. The following aspects were considered, reproduction and breeding cycles, sex determination, fecundity and Gonado – Samatic Index (GSI). Table 1 and 2 show the summary of the results obtained. While tables 3-12 show the detailed results obtained for the different stages of maturity and gonad development. The Gonado Somatic Index (GSI) was calculated as the percentage of Gonad-weight per body weight. Fecundity was determined by direct enumeration using a digital counter and egg diameter was determined using ocular eye piece with stage micrometer. Keywords: Reproduction, fecundity, Gonad Somatic Index (GSI)
Effect Of Stocking Density On Survival And Body Composition Of Nile Tilapia (Oreochromis Niloticus) Fed MULTI Feed And NIOMR Feed In Semi Flow-Through Culture System.
This study was carried out to investigate the growth response and body composition of Nile tilapia; O. niloticusto two feed type: MULTI feed (foreign) and NIOMR feed (local) of 32% and 44% crude protein (CP)respectively at three stocking densities 158, 237 and 316/m3 in semi-flow through culture system. Theexperiments were conducted in two phases in succession using twelve (12) circular fibre glass tanks stocked withmixed sex fingerlings of Nile tilapia of average weight of 6.8g at the three stocking densities and cultured for aperiod of 24 weeks. The result of the study showed significantly (P < 0.05) highest growth, feed conversion andsurvival rate in treatment II (MULTI feed at 158 fish/m3) while significantly lowest growth rate and feedconversion was recorded in treatment V. The lowest survival rate (94.02%) was recorded in treatment VI. Interms of the proximate composition of the Nile tilapia fed the experimental diets; treatments that were fed withMulti feed (II, IV, and VI) showed higher values than fish fed with NIOMR diet (I, III, and V) at equivalentstocking densities at the end of the trial. All water quality parameters are within the acceptable and suitable rangefor proper growth of O. niloticus. Based on the overall growth performance; treatment II at stocking density of158 fish/m3 fed Multi feed is recommended.Keywords: Nile tilapia, stocking density, growth performance, body composition, flow-through system
