Aim: The aim of the study is to identify helminth parasites in the gastrointestinal tract of Oreochromis niloticus in Dadin Kowa Dam, Yamaltu Deba Local Government Area, Gombe State. Study design:  Oreochromis niloticus fish species were randomly obtained from the local fishermen in the landing sites; between 7:00am-10:00am weekly. Place and duration of study: The study was carried out at Dadin Kowa Dam in Yamaltu Deba Local Government Area of Gombe State between the months of March to June, 2019. Methodology: 60 Oreochromis niloticus (Nile Tilapia) were obtained and examined for gastro intestinal parasites. Sex of the fish was determined by the presence and absent of an intromittent organ. The total length, standard length and body weight was measured using standard method. Dissection was done using standard procedure and the Parasites recovered were identified using the helminth parasites of fish identification guide. Results: Out of the 60 fish species examined. (23 female and 37 males), 21 (35.00%) were infected and were observed to habour six (6) endoparasites; viz nematodes, Cestodes and trematodes. The results show that there was a significant difference between infection rate, total length and weight of fish with female species having relatively higher percentage prevalence 11(43.50%) than the males 10 (29.70%). It was observed that the prevalence of parasitic infection increase with length and weight of the fish. Conclusion: Presence of these fish helminth parasites may lead to devaluation in protein constant in the body of the fish. The work therefore recommends water quality assessment of Dams as it is one of the factors that bring about the increase in parasitic infection.

Organic and inorganic pollutants such as N, P, and heavy metals are a serious problem in water bodies (lake, reservoir, river, and stream) and have deleterious effects to pond productivity and human health. These pollutants produced from anthropogenic activities (i.e. industrial, agricultural, and settlement) are released into the water bodies and causing poor water quality. Constructed wetland (CW) is one of the technologies that have the capability to solve such problems. The purpose of this experiment was to examine the efficiency of constructed wetland in terms of reducing pollutants from the stream as a water resource for aquaculture area and increasing fish production. Two kinds of treatments were set up: one fish pond culture with constructed wetland and the other one without constructed wetland (control). Each treatment consisted of three replications. The result showed that water quality in the fish pond with CW was better than the control. Constructed wetland were able to reduce ammonia (NH3-N), nitrite (NO2-N), nitrate (NO3-N), TN, phosphate (PO4-P), TP, Cu, Pb, and As concentrations to 15.00%-88.27%, 9.52%-72.73%, 11.11%-57.14%, 20%-66.67%, 24.44%-80.77%, 12.04%-77.95%, 50.00%-100%, 56.25%-100%, and 46.83%-100%, respectively. Nile tilapia cultured in pond using CW was higher than the control in terms of total length, body weight, and survival rate. The t test revealed that nile tilapia (Oreochromis niloticus) cultured in pond with CW and the control has significant difference (P<0.01) in terms of total length, body weight, and survival rate. This is the evidence that constructed wetland technology is very useful on improving water quality and increasing pond productivity of nile tilapia cultured in the freshwaterpond.

To investigate the morphological variations 12 morphometric and 11meristic characters were studied for 100 individuals of the same age of traditional strain GIFT (5th generation) and recently developed 11th generation strain    (GIFU) of Nile tilapia, Oreochromis niloticus. No significant difference was found between total length and other body measurements at 5% level. However, GIFU showed faster linear growth on body depth, maximum body circumference and minimum body circumference where GIFT showed faster linear growth on standard length and head length. On meristic characters, notable variations were observed in case of scale above and below the lateral line, where GIFU individuals showed greater number of scales in both cases. The total length and body weight relationship of both the strains were found to be straight line in logarithmic scales. The mean values of condition factor (K) have been found to be 1.671 for GIFT and 1.711 for GIFU and the mean values of relative condition facto (Kn) were 1.001 and 1.002 for GIFT and GIFU respectively. Findings of the present study suggested the variability of strain GIFU and GIFT in some important parameters.   DOI: http://dx.doi.org/10.3329/jbau.v9i2.11050   J. Bangladesh Agril.

Feed Conversion Rate

The performance of Nile tilapia (Oreochromis niloticus) raised in cages furnished with an automatic dispenser, supplied at different frequencies (once per hour and once every two hours) and periods (daytime, nighttime and both) was evaluated. Eighteen 1.0m³ cages were placed into a 2000m² pond, two meters deep with a 5% water exchange. One hundred and seventy tilapias, with initial weight of 16.0±4.9g, were dispersed into each 1m³ cage and the feed ration was adjusted every 21 days with biometry. Data was collected from March to July (autumn and winter). Significant difference to final weight (P<0.05) among treatments was observed. The increase in feeding frequency improves the productive performance of Nile tilapias in cages and permitted better management of the food. The better feed conversion rate for high feeding frequency (24 times day-1) can result in saving up to 360kg of food for each ton of fish produced, increasing the economic sustenance for tilapia culture and suggesting less environmental pollution.

ABSTRACTSoil transmitted helminthes (STHs) are common public health concern among children in Sub saharan Africa. A study to determine the prevalence and intensity of these parasites among pupils of two primary schools in Nkpor and Mgbodohia communities, Obio/Akpor Local Government Area, Rivers State, Nigeria was conducted. The formo-ether concentration technique was used to concentrate and separate the eggs and cysts from the faeces. Out of 107 pupils (56males and 51 females) investigated, 81 (75.7 %) were positive for at least one gastrointestinal helminth. The parasites identified included Ascaris lumbricoide(58.0%), Hookworms(28.4%), Trichirus trichiura(13.6%) and A.lumbricoide + T. trichiura (6.3%). Ascaris lumbricoide was significantly (P<0.05) higher in prevalence than other parasites. Although more females (54.3%) were infected than males (45.7%), there was no significance(P>0.05) difference in the prevalence in relation to sex. Of the 44 males infected, 24(54.5%), 5 (11.4%), 13(29.5%) and 2(4.5%) haboured A. lumbricoide, T. trichiura, Hookworms and mixed infection (A. lumbricoide + T. trichiura) repectively. Out of the 37 females infected, 21 (56.8%), 3(8.1%), 10(27.0%) and 3(8.1%) haboured A. lumbricoide, T. trichiura, Hookworms and mixed infection (A. lumbricoide + T. trichiura) repectively. There was no significance difference in the prevalence of A. lumbricoide and Hookworms between males (54.5%) and females (56.8%). There was significant difference in prevalence among two major age groups (5-10years-45% and 11-15years-41.9%). Children within the age group of 16-20years had the least infection (9.9%). The intensities of A.lumbricoide, T.trichiura and hookworm were 246.5, 107.5 and 187 Epg respectively. The intensity of A. lumbricoide was significantly difference than other parasites identified.Soil transmited helminthes remain a public health concern among children in the study area. Provision of portable water, toilet facilities, good education on the epidemiology of STHs and regular de-worming will enhance control measures.

Intestinal Parasitic Infection

Intestinal parasitic infections have always been an important public health problem in the tropics particularly in developing countries such as Nigeria for example. A cross-sectional survey involving 440 schools going children of both sexes aged 6 - >12 years was conducted in 4 primary schools at a different location in Doma Local Government Area (LGA) of Nasarawa State, Nigeria, between September 2015 to February 2016 to determine the prevalence of intestinal parasites. Of the 440 samples examined 155 (35.22%) were infected with different intestinal parasites. The parasites observed included Entamoeba histolytica (6.59%), bookworm (5.22%), Ascaris lumbricoides (53.40%), Trichuris trichiuria (0.45%), E. coli (4.77%) and mixed infection of Ascaris lumbricoides and hookworm (7.27%) with Ascaris lumbricoides having the highest prevalence. Doma south primary school 38 (34.54) Islamiyya nursery/primary school and Doma west primary school had the lowest prevalence with 36 (32.72%) and 34 (30.90%) respectively. An overall prevalence of (35.22%) intestinal parasitic infection in school going children is moderately high and of public health concern. There is need to intensified integrated control measure to reduce or completely eradicate the intestinal parasitic infection in school pupils.

Academic achievement of students does not depend only on school, environmental factors and teacher characteristics, but also on the level of home involvement. This study therefore sought to establish the extent of parental school involvement for students’ improved academic achievement in Awka South Local Government Area of Anambra State. The descriptive survey design was used for this study, with six (6) research questions guiding the study. The population for the study comprised 417 public secondary school teachers from which a sample of 125 teachers using simple random sampling technique. The instrument for data collection was a researcher designed, structured questionnaire which was duly validated by experts in educational management and measurement and evaluation. The questionnaire was tested for reliability using test-retest method. The tool for correlation was the Pearson Product Moment Correlation and this yielded a co-efficient of 0.82. Data collected was analysed using mean and standard deviation statistics to answer the 6 research questions while ANOVA with Friedman’s Test was used to test for significant difference in the six indices of parental involvement. The findings show among others that teachers perceive that parents in Awka South Local Government Area effectively communicate with school and coach their children for improved academic achievement to a moderate extent. There was no significant difference in the teacher’s perception of parental involvement based on the six indices of involvement. Based on the findings, the researchers recommended among others, that parents and the school use social media and other devices to communicate more effectively with the school for improved students’ academic performance.

Introduksi ikan nila atau “serapia” (Oreochromis niloticus) di Danau Paniai bertujuan untuk meningkatkan diversitas hasil tangkapan dan mengurangi tekanan eksploitasi terhadap jenis ikan endemik. Pertumbuhan dan produksi ikan nila yang cepat tanpa diiringi upaya pengelolaan akan mengancam keberlanjutan ikan endemik di danau. Upaya pengelolaan sumberdaya ikan di suatu perairan membutuhkan informasi dinamika populasi. Penelitian dinamika dan pengelolaan populasi ikan nila dilakukan pada bulan Februari sampai Oktober 2016. Contoh ikan dikumpulkan dari hasil tangkapan nelayan dengan menggunakan jaring insang dengan berbagai ukuran mata jaring dan dari 4 (empat) enumerator pada tujuh stasiun pengamatan. Hasil penelitian menunjukkan populasi ikan nila di Danau Paniai didominasi ukuran panjang individu antara 15-25 cm sebanyak 67,24%. Pola pertumbuhan ikan jantan dan betina adalah isometrik, panjang maksimum rata-rata (L) adalah 37,28 cm dan koefisien pertumbuhan (K) adalah 0,50 per tahun. Mortalitas alami (M) dan mortalitas penangkapan (F) masing-masing sebesar 0,99 dan 0,54 per tahun. Tingkat eksploitasi (E) diperoleh nilai 0,35 lebih kecil dari nilai optimum (E=0,5). Ukuran rata-rata ikan nila tertangkap (Lc) adalah 20,55 cm lebih besar dari ukuran pertama matang gonad (Lm) sebesar 14,73 cm. Nilai Lc>Lm mengindikasikan sebagian besar populasi ikan nila di Danau Paniai sempat melakukan pemijahan sehingga pemanfaatan lebih atau sama dengan nilai optimum diharapkan dapat meningkatkan pemanfataan ikan nila di Danau Paniai. Introduction of nile tilapia (Oreochromis niloticus) in Lake Paniai known as “serapia” is aimed for improving the diversity of catches and reducing the exploitation pressure on the endemic fish species. The rapid growth, reproduction and production of nile tilapia without its management efforts is a new threat to the sustainability of the existence and utilization of endemic fish species in the lake. Management efforts of fish resources require population dynamics information. Research on the dynamics and management of nile tilapia populations was conducted from February to October 2016. Fish samples were collected from fishermen catches using nets with various mesh sizes and from four enumerators at seven observation stations. The results showed that the population of nile tilapia in Lake Paniai was dominated by individual length between 15-25 cm with frequency of 67,24%. The growth pattern of male and female fish were isometric, the average maximum length (L) was 37.28 cm and the growth coefficient (K) was 0.50 per year. Natural mortality (M) and fishing mortality (F) were 0.99 and 0.54 per year respectively. Exploitation rate (E) of 0.35 was smaller than the optimum value (E=0.5). The average size of nile tilapia captured (Lc) was 20.55 cm larger than the first size of gonad maturity (Lm) of 14.73 cm. The Lc value was higher than that the Lm value(Lc>Lm) indicating that most of nile tilapia population in Lake Paniai has spawned so that increasing the more or equal to the optimum value was expected to improve the of nile tilapia fish in Lake Paniai.

This study investigated the length-weight relationships and condition factors of three fish species in an abandoned gold mine reservoir. The fishes were caught on monthly basis between August 2015 and July 2016 using gill nets and traps. The results showed that Coptodon zillii, Oreochromis niloticus and Sarotherodon galilaeus had a mean total length and mean weight of 15.52±4.64 cm and 95.80±66.27 g; 15.27±4.18 cm and 89.54±63.20 g; 15.57±4.80 cm and 102.0±85.81 g respectively. Also, the mean condition factor obtained for the fish species are 2.24±0.52 in C. zillii; 2.26±0.62 in O. niloticus and 2.27±0.46 in S. galilaeus. Similarly, the slope (b) values and correlation coefficient for the three fish species are 2.018 and 0.969 for C. zillii; 1.977 and 0.926 for O. niloticus and 2.436 and 0.965 for S. galilaeus. Furthermore, the total length, weight and condition factor between C. zillii, O. niloticus and S. galilaeus differ significantly (p>0.05). The study concluded that despite being an abandoned gold mine reservoir, the environment is well suitable for the fishes.

This study examined the effects of self-regulated learning instructional strategy on students’ achievement in basic science among Upper Basic 2 in Makurdi Local Government Area of Benue State. The study employed non-equivalent group pre-test-post-test quasi experimental design. The population of the study was 638 upper basic school levels. The sample for this study was 128 students from six co-educational schools within Makurdi Local Government Area of Benue State. Two research questions and two hypotheses guided the study. The instrument used for data collection was Basic Science Achievement Test (BSAT) and was trial tested using Kuder-Richardson (K-R, 20) formula to determine the reliability coefficient of BSAT which was found to be 0.99. Descriptive statistics of means and standard deviation were used to answer all the research questions and inferential statistics of Analysis of Covariance (ANCOVA) was used to test all the hypotheses at 0.05 significant level. The results of the study showed that demonstration method enhanced students’ achievement in basic science better than self-regulated strategy. There is no significant difference between the mean achievement score of students taught basic science using self-regulated learning strategy and those taught using demonstration method. There was no significant difference between the mean achievement scores of male and female students taught basic science using self-regulate learning strategy. Basic science Teachers should not only use demonstration method to teach but also allow the student to actively participate in the learning. This can foster confidence in the students and enhance better achievement in basic science.
