SURVIVAL AND GROWTH PERFORMANCE OF CLARIID CATFISH HYBRID (Clarias gariepinus x Heterobranchus bidorsalis) LARVAE USING TWO FERTILIZATION-BASED FEEDING STRATEGIES

Faculty: 
Agriculture

 

The survival and growth performance of hatchlings of clariid catfish hybrid (Clarias gariepinus x Heterobranchus bidorsalis) were examined in two fertilization-based feeding strateies: organic fertilization (ORF) and a combination of organic/chemical fertilization (COC).  The study was conducted using six 25-L circular tanks each 
having an area of 0.7m2 in a complete randomized design with treatments replicated three times.

GROWTH PERFORMANCE OF OREOCHROMIS NILOTICUS IN COMBINATION WITH CLARIID CATFISHES IN MONOCULTURE AND POLYCULTURE

Faculty: 
Agriculture

 

The growth performance of Oreochromis niloticus in polyculture with clariid catfishes was studied.  The experiment ws designed as two (stocking ratio) by three (species combination) factorial in a completely randomized design.  Monoculture of O. niloticus served as the control.  Each treatment was replicated three times.

AGE AND GROWTH DETERMINATION IN CITHARINUS CITHARUS (GEOFFREY AND ST. HILAIRE, 1809) IN ONAH LAKE, DELTA STATE, NIGERIA

Faculty: 
Agriculture

 

An observation of the rings impressed on the polished sagittae otoliths of Citharinus citharus in the present study revealed reliable age data.  Two daily rings were counted on the otoliths.  These rings resulted from other factors including growth increments.  Two types of rings (periodic and daily) were described.  Two periodic rings were counted annually while the daily rings were impressed in multiples of two.  Growth increments were also observed on scales.

Effect of Brewery Effluent into Ikpoba River on the Growth of Two Chlorophytes

Faculty: 
Life Sciences

 The algal bioassay technique was used to investigate the effect of Guinness brewery effluent discharged in to the Ikpoba River in Benin City, Edo State of Nigeria. Selenastrum capricornutum  Printz and Chlorella vulgaris Bejik were grown in test waters collected from the following point; ‘before the discharge’ of the effluent, the ‘point of discharge’ and the point ‘after discharge’. Mineral nutrients were least at the site `before' discharge than the other two sites.

GROWTH OF OKRA (ABELMOSCHUS ESCULENTUS) ON SOIL OBTAINED NEAR A GAS FLARING SITE (OBEN) IN EDO STATE, NIGERIA

Faculty: 
Life Sciences

An investigation into the growth of okra on soil obtained from Oben (SPDC gas flaring site) was undertaken. Seedling emergence, shoot height and leaf area of 28-day old crop sown on soil dug 90 m away from the flare site was significantly reduced when compared to control. Also the activities of amylase, phosphorylase and protease extracted from 5- day old cotyledon were markedly inhibited when the crop was grown on both top and subsoil obtained 90 m from flare site.
