During spawning, increasing the length and weight of gonads from immature to ripe, maximum values of GSI for both sexes (3.43%-3.49% to 4.09%- 6.01%) were obtained during April to August with peak in July.

The aquaculture knowledge of the fish farmers on different aspect of pond fish culture practices such as, pond biology, pond preparation, species selection and stocking density, water colour monitoring, pond fertilization, feed and feeding, disease control, harvesting and restocking, risk management and marketing revealed that most of the fish farmers belonged to low knowledge category.

However, there is currently dearth of information on the growth pattern and state of well-being of Parachanna obscura in Eleyele Reservoir. This study therefore investigates the allometry and condition factor of P. obscura inhabiting the Eleyele Reservoir, Southwestern Nigeria. 688 specimens of P. obscura were collected from artisanal fishers’ at their landing sites on a bimonthly basis for 24 months. Standard Length (SL, cm), and Body Weight (BW, g) were measured. Length-Weight Relationships (b>3 or <3-allometric; b=3-isometric), and condition factor (K) were calculated using standard formula. Data were analysed using descriptive statistics and ANOVA at α0.05. The SL and BW of P. obscura ranged from 10.6 to 39.2 and 15.3 to 830.5 respectively. The LWR were 3.04 (male) and 2.99 (female) indicating positive allometric pattern of growth in male and negative allometric growth in female. The growth coefficient b ranged between 2.877 in July and 3.348 in May, with very significant coefficient of determination r2 for all the months. Variations recorded in the b value of different size groups showed positive allometric growth in 10.1 cm -15.0 cm, 15.1 cm -20.0 cm and 20.1 cm -25.0 cm, but negative allometric growth in 25.1 cm -30.0 cm and 30.1 cm -40.0 cm. The maximum (1.54 ± 0.12) K was noticed during March 2016 and the minimum (1.30 ± 0.7) K in September 2015. Significant variation occurred in K with size groups. The mean K value in females (1.43 ± 0.21 and 1.44 ± 0.20) was higher than males (1.40 ± 0.18 and 1.42 ± 0.17) for 2014-2015 and 2015-2016, respectively.

The hepatopancreatic cells, spermatogonium, gill tissues and muscle cells of the diseased crabs showed severe structural and morphological changes. To further investigate whether HPND was caused by pathogenic microorganism, the healthy crabs were fed/injected with diseased tissues, the symptoms of HPND were not found, suggesting that HPND was not caused by virus or microsporidian infections. In addition, the toxic effect of avermectin and high pH water were also examined in this study. 40% (p<0.01) crabs with HPND symptoms were found after breeding crabs in water with 9.5 pH to 10 pH for 14 days, but the crabs with no HPND symptoms were found when they were raised in water with different concentrations of avermectin.

Heavy metals pollution has become a worldwide concern and this may be due to their ability to bioaccumulate in aquatic organisms which is a source of livelihood for human populations. Therefore, this work aimed at assessing heavy metal accumulation in Clarias buthupogon and Heterobranchus longifilis in Asa River, Nigeria. After reconnaissance survey, fish samples were collected using hooks, traps and cast nets of various sizes twice monthly between April 2011 and March 2013 and were identified immediately. The samples were processed and heavy metal concentrations were determined in the gill, liver and muscle using atomic absorption spectrophotometer. Different metals were analysed in the gill, liver and muscle of the sampled fish species and the data obtained were subjected to statistical analysis using the T-test statistical package to determine the level of difference between means. The results in (mg kg-1, dry weight) showed different levels of the analysed metals in the two fish species. The order of heavy metals accumulation in the two fish species are gills>liver>muscle and the levels of heavy metals bioaccumulation varied significantly (p<0.05) among season, sample locations, fish species and fish organs. All metals analysed vary significantly in the two fish species examined, seasons and across sampling sites. The results suggest that Asa River has high pollution loads of these heavy metals in fishes due to an indiscriminate of discharge of effluents in the river and could pose a health hazards to man. Consequently, close monitoring of heavy metal loads in Asa River is recommended with a view of minimizing the risks to health of the population that depend on the river for their water and fish supply.","PeriodicalId":166175,"journal":{"name":"Fisheries and Aquaculture Journal","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116933957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
