Abstract Aquaculture assist in bridging the wide gap by meeting demands for fish and provision of less expensive animal protein in Nigeria. Clarias gariepinus and Heterobranchus bidorsalis are generally acceptable important species of catfish, and highly priced because of their high biological values in terms of protein retention, assimilation and low cholesterol content, necessitating the need to evaluate their potentials. Fingerlings of Clarias gariepinus (purebreed) and Clariabranchus (hybrid) were grouped according to their weights, assigned to two tanks each and fed 5% of their body weight daily. Measurements of body weight (g), total length (cm) and standard length (cm) were taken weekly on each fish. At the commencement of the experiment, there were 281 fishes comprising 150 purebreed and 131 hybrid. By the end of the study (21 days), some died or were outliers and a total of 224 fishes comprising 108 purebreed and 116 hybrid were finally evaluated. Indices computed included Length-Weight Relationship (LWR), Fulton’s Condition Factor (K), Absolute Growth Rate (AGR), Specific Growth Rate (SGR), Relative Growth Rate (RGR) and Mean Growth Rate (MGR). The coefficient of the LWR was respectively 2.42 and 2.82 for the pure breed and hybrids. Effect of breed was highly significant (P < 0.01) on all variables studied and the hybrid consistently outperformed the pure breed except in exception of condition factor which is a measure of wellness of the fish (Table 1). The superiority of the hybrid in all variables studied except condition factor, is indicative of its potential as a better feed converter, thus it is more efficient in feed utilization, and it is recommended for commercial fish producers for maximum yield and higher profit. The study provides a veritable platform for further research on the potentials of interspecific hybridization with a view to minimizing production cost engendered by high cost of feed.

Feeding Regimen

An experiment was conducted using 270 African catfish fingerlings to evaluate the effects ofdifferent feeding regimen on growth performance of the fish. The fish were hatched andreared to 12 weeks under similar condition before the commencement of the experiment thatlasted for 40 days. Feeding regimens included equally shared feed based on recommended of5% body weight, and equally spaced feed allocation at 6, 8 and 12 hourly intervals. Each ofthe three treatment groups comprised of six replicates of 15 fish per plastic tank. Body weight,and two linear measurements (total and standard length) were taken twice weekly on each ofthe fish in all the tanks and the respective length-weight relationship and condition factor (K)were computed. Weekly gain, final weight, average daily gain, absolute, relative, specific andmean growth rates for the three groups were evaluated and compared. Results showed that allparameters studied except final total length were significantly (P<.05) affected by feedingregimen. The coefficient of determination for all ANOVA had variable values for all growthparameter; Final Weight (83.11%), Absolute Growth Rate (79.19%), Final Total Length(61.30%), Final Standard Length (60.87%), Relative Growth Rate (38.68%), SpecificGrowth Rate (35.57%), Mean Growth Rate (32.23%) and Condition Factor (12.83%). The 6-hourly treatment group mostly had the highest values across all the parameters studied butwas not statistically different (P>.05) from the values obtained in the 8-hourly group.

Fish found in natural tropical and sub-tropical water system experience frequent growth fluctuations. The study was conducted to determine the length-weight relationship and condition factor of Clariid species (Clarias gariepinus, Heterobranchus longifilis and Synodontis clarias) in Kano state of Nigeria. About 177 fish samples were collected from six rivers (Thomas, Ghari, Tiga, Duddurun-Gaya, Karaye and Bagwai) across the length and breadth of Kano state. Body weight (BW=248.48g), total length (TL=32.74cm) and standard length (SL=26.16cm) were determined. The length-weight relationship and condition factors were also determined. The condition factors showed varying degree of well-being of fish sampled from their habitat, and ranged from K = 0.37 to 0.89. The equation for the lengthweight relationship for the three strains is: C. gariepinus = -329.86+17.56TL, H. longifilis = -241.49+14.28TL and C. clarias = -428.51+22.72TL. Body weight and length had positive and significant relationship (r = 0.73 TL; r = 0.75 SL).

The study was performed to examine the efficiency of hybrid napier grass (CO-3) mixed diet on growth performance of freshwater fish Ctenopharyngodon idella. Alive grass carp fingerlings were collected from commercial fish farm in Thanjavur from June 2015 to May 2016. Fishes were divided into two groups and acclimated for 7 days before feeding trial. The fishes were fed with control and experimental diet. The growth parameters such ABW, ABL, BWG and SGR were thoroughly studied adopting standard procedure. The result of the study clearly indicates that there was a significant variation in growth of control and experimental fishes. The fish fed with CO-3 grass mixed diet showed elevated level in body weight, body length, weight gain and specific growth rate. This study suggests that the CO-3 grass mixed diet is more suitable for grass carp aquaculture practice. Keywords: Hybrid Napier grass, CO-3, Ctenopharyngodon idella, Specific growth rate.

Monoculture is the rearing of single species of fish in a pond while polyculture is the farming of two or more species in the same physical space. This study aims to compare the growth parameters of Clarias gariepinus fingerlings in monoculture and polyculture, using concrete and earthen ponds in a randomized complete block design. The polyculture, comprised of Clarias gariepinus and Oreochromis niloticus. 480 fingerlings were used; the stocking density was 40fish in a 3x2x1.5m depth with initial weight (4.84±0.11547) for C. gariepinus in monoculture and 40 each in polyculture with an initial pooled weight of O. niloticus (50g) replicated thrice, it was fed for eight weeks with commercial feed (40% crude protein). Weekly, random sampling was done to measure the growth and adjust the feeding rate. The results revealed that polyculture has the best mean final weight (160.07±0.18559g) and weight gain of 155.29, while the highest total length (45.666±3.179) was recorded in monoculture for Clarias gariepinus reared in an earthen pond. The polyculture had the highest specific growth rate (2.46), Relative growth rate (246.49), and condition factor (0.184). There was a significant difference (P<0.05) in monoculture of both concrete and earthen ponds.

Economic performance of using Coppens (commercial fish feed) and locally formulated feeds for Clarias gariepinus culture was studied. Forty juveniles averaging a total length of 9.15 ± 0.17cm and weight of 20.00 ± 2.58g were used and fed twice daily at 3% of their body weight. The weight gain (WG), growth rate (GR) and specific growth rate (SGR) varied significantly (p<0.05), while mean growth rate (MGR) varied insignificantly between treatment groups (p>0.05). Water parameters were at the required level. Cost of experimental feed per kilogram was highest in Coppens (₦733.33 ($2.156853)/kg) but lowest for chicken offal based diet (COBD) (₦267.00 ($0.785294)/kg). Feed consumption was higher for Coppens group (41650.00g ± 315.34) but lowest for COBD group (38276.00g ± 432.97). Cost of feeding (FC) was lower for COBD group (₦ 10219.69 ($30.057912) ±115.60) but higher in shrimp based diet (SBD) group (₦ 30,543.19 ($89.832912) ± 231.25). The ICA was higher in fish fed Coppens (₦ 1933.33 ($5.686265) ± 0.00) but lower for COBD group (₦1467.00 ($4.314706) ± 0.00). The NPV was higher in fish fed Coppens (₦ 440998.26 ($1297.053706) ±11636.93), but lower in COBD group (₦ 132916.16 ($390.929882) ± 3297.24). The PI was highest in Coppens group (₦14.44 ($0.042471) ± 0.35) but lowest in COBD group (₦ 13.01 ($0.038265) ± 0.43). The GP was higher in Coppens group (₦439064.93 ($1291.367441) ± 11636.93) but lower in COBD group (₦131449.16 ($386.615176) ± 3297.24). The IC was higher in Coppens group (₦228.10 ($0.670882) ± 6.02) but lower in COBD group (₦90.61 ($0.266500) ± 2.25). The BCR was higher in fish fed coppens (1.78±0.04) but lowest in COBD group (0.71±0.01). Feed consumed, FC, ICA, NPV, PI, GP and IC varied significantly (p<0.05), while BCR varied insignificantly (p>0.05) between treatment group. The SBD and COBD were as effective as Coppens in terms of growth performance and economic benefits. More researches should be carried out on the use of locally formulated feeds in aquaculture.

Photoperiod Manipulation

Changing in photoperiod duration will affects the physiology of fish in general. A study aims to understand the effects of photoperiod manipulation towards C. gariepinus morpho-anatomy and growth was conducted on March–May 2018. The fishes were reared in fiber tanks (140 x 60 x 40 cm) that was filled with water and completed with a circulatory system. Treatments applied were Control (natural photoperiod), 24G (24 hours dark), 18G6T (18 hours dark and 6 hours light), and 6G18T (6 hours dark and 18 hours light). The fishes were sampled once/14 days, 4 fishes/ aquarium/sampling. Parameters measured were length-weight relationship, condition factor, hepatosomatic index (HSI), viscerasomatic index (VSI), absolute length and weight, food conversion ratio (FCR), gonad development and body protein/fat. Results shown that photoperiod manipulation affects C. gariepinus morpho-anatomy and growth. The highest growth parameters and morpho-anotomy index were found in fish reared in 18G6T. By the end of the experiment, the b value of   length-weight relationship was 3.3205, absolute weight and length were 86.70 g and 17.23 cm, condition factor was 0.84, VSI was 25.31%, HSI was 11.42%, FCR was 1.43, and body protein and fat was 48.40% and 50.38%. In the fish reared in 24G treatment, b was 1.9262, 52.13 g BW and 14.19 cm SL, condition factor was 0.80, VSI was 23.30%, HSI was 9.38%, FCR was 2.47, and body protein and fat was 48.08% and 49.53%. In the fish reared in 6G18T, b was 2.6903,49.45 g BW and 13.79 cm SL, condition factor was 0.79, VSI was 23.30%, HSI was 6.80%, FCR was 1.91, and body protein and fat was 46.64% and 49.00%. Fish reared in natural photoperiod (control) shown the lowest results b was 2.0418, 51.68 g BW and 14.21 cm SL, condition factor was 0.79, VSI was 19.58%, HSI was 6.96%, FCR was 2.20, and body protein and fat was 43.95% and 47.77%.Early developing gonad (1st maturity stage) was only found in fish reared in 18G6T. Based on data obtained it can be concluded that the photoperiod manipulation affect the morpho-anatomy and growth of C. gariepinus.

Clarias gariepinus juveniles of average weight, 17.57±1.95 g and an average length of 14.26±0.39 cm were exposed to environmentally relevant concentrations of 0 (control), 2.5, 25, 250, and 500 µg L-1 atrazine in a quality-controlled 28-day bioassay. Growth performance was assessed bi-weekly and fish samples were taken from different tanks to determine the relative growth rate, specific growth rate, feed conversion ratio, condition factor and behaviour. At the end of two weeks of exposure, the relative growth rate and the specific growth rate among exposed fish groups was found to reduce significantly (p<0.05) compared to the control, an indication of poor growth performance. The average specific growth rates (SGR) of control fish is 3.86±0.02 %/w at the end of the exposure duration while recording -0.64±0.09 in the 500 µg L-1 group. Feed conversion ratio increased significantly from control to the group with highest atrazine concentration. Condition factor (K) of fish among treatment groups showed significant decrease in values with increasing concentration of atrazine in a dose-dependent pattern. Atrazine exposure resulted in behavioural anomalies including erratic swimming, clinging to the water surface, loss of equilibrium, lethargy, and discolouration. The behavioural responses were found to be concentration-dependent. The length-weight relationships for both control and atrazine exposed fish exhibited positive allometric growth and significant relationships as depicted by the value of R2 (coefficient of determination) except in the fish group exposed to 500 µg L-1 atrazine which exhibited negative allometric growth. Findings from this study indicate interference with normal behaviour and growth performance of C. gariepinus juveniles with ecological implications in water bodies exposed to atrazine even at reduced concentrations.

Gourami (Osphronemus gouramy Lac.) as one of the freshwater fishes, are easily to be cultured but slow in growth rate. One of the ways to enhance their growth rate is by feeding them with high nutritious food. Sargassum sp. and inositol are known compound able to stimulate the growth of some fishes. The study was conducted to determine the effect of Sargassum sp and inositol on commercial feed to the growth rate and survival of juvenile gouramy. The study was conducted from January to April 2015 in Aquatic Laboratory of Biology Department - University of Lampung. Completely randomized designed was used with 4 treatment groups and 5 replications. Anova and Tukey at 5% levels were applied to this study. The result indicated that addition of inositol and Sargassum sp on commercial food significantly affected the gourami growth parameters such as the body weight, body length, body width as well as juvenile gouramy spesific growth rate and their survival rate.

The aim of this study was to determine changes in selected growth parameters of farm-raised mallard ducklings from hatch to 42 d of age. The largest increases in body and carcass weights of ducklings and weights of the analyzed tissue components were noted during the first 28 d of the rearing period, except for breast and wing muscles. In comparison with other muscle groups, the growth rate of breast and wing muscles was lower from hatch to 14 d of age, greatest between 14 and 28 d, and remained high up to 42 d of age. The average body weight of mallard ducklings increased more than 16-fold (from 39.7 to 644.8 g, P ≤ 0.01), and the average carcass weight increased more than 26-fold (from 14.4 to 384.5 g, P ≤ 0.01). The growth rates of carcass and tissue components varied considerably. Wing weight increased 84.5-fold (from 0.80 to 67.6 g, P ≤ 0.01), followed by breast weight, which increased 48-fold (from 1.7 to 82.9 g, P ≤ 0.01). Slower growth rates were noted in the remaining carcass parts: back, 23-fold; neck, 19.2-fold; and legs, 17.1-fold (from 5.4 to 92.2 g, P ≤ 0.01).

Fish plasma/serum contains multiple IGF binding proteins (IGFBPs), although their identity and physiological regulation are poorly understood. In salmon plasma, at least three IGFBPs with molecular masses of 22, 28 and 41 kDa are detected by Western ligand blotting. The 22 kDa IGFBP has recently been identified as a homolog of mammalian IGFBP-1. In the present study, an RIA for salmon IGFBP-1 was established and regulation of IGFBP-1 by food intake and temperature, and changes in IGFBP-1 during smoltification, were examined. Purified IGFBP-1 from serum was used for as a standard, for tracer preparation and for antiserum production. Cross-linking 125I-labelled IGFBP-1 with salmon IGF-I eliminated interference by IGFs. The RIA had little cross-reactivity with salmon 28 and 41 kDa IGFBPs (< 0·5%) and measured IGFBP-1 levels as low as 0·1 ng/ml. Fasted fish had significantly higher IGFBP-1 levels than fed fish (21·6 ± 4·6 vs 3·0 ± 2·2 ng/ml). Plasma IGFBP-1 was measured in individually tagged 1-year-old coho salmon reared for 10 weeks under four different feeding regimes as follows: high constant (2% body weight/day), medium constant (1% body weight/day), high variable (2% to 0·5% body weight/day) and medium variable (1% to 0·5% body weight/day). Fish fed with the high ration had lower IGFBP-1 levels than those fed with the medium ration. Circulating IGFBP-1 increased following a drop in feeding ration to 0·5% and returned to the basal levels when feeding ration was increased. Another group of coho salmon were reared for 9 weeks under different water temperatures (11 or 7°C) and feeding rations (1·75, 1 or 0·5% body weight/day). Circulating IGFBP-1 levels were separated by temperature during the first 4 weeks; a combined effect of temperature and feeding ration was seen in week 7; only feeding ration influenced IGFBP-1 level thereafter. These results indicate that IGFBP-1 is responsive to moderate nutritional and temperature changes. There was a clear trend that circulating IGFBP-1 levels were negatively correlated with body weight, condition factor (body weight/body length3 × 100), growth rates and circulating 41 kDa IGFBP levels but not IGF-I levels. During parr–smolt transformation of coho salmon, IGFBP-1 levels showed a transient peak in late April, which was opposite to the changes in condition factor. Together, these findings suggest that salmon IGFBP-1 is inhibitory to IGF action. In addition, IGFBP-1 responds to moderate changes in dietary ration and temperature, and shows a significant negative relationship to condition factor.
