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 Mean

The knowledge of length-weight relationship parameters has numerous practical applications in fishery research and management. Currently, there is a dearth of information on the growth pattern and state of well-being of Parachanna africana in Ijede and Agbowa Lagoons. This study period was between December 2017, and June 2018 investigated the allometry and condition factor of P. africana inhabiting the Ijede and Agbowa Lagoons, South-western Nigeria. Two hundred fish samples of P. africana was gotten from fishermen at both locations. The length and weight measurements were taken to the nearest centimetres and grams. Descriptive, correlation and regression tools, was used to 2analyse the data collected. Results obtained showed that the length-weight relationship had r values of  0.186, 0.196, 0.191 and 0.341, 0.001, 0.098 for Ijede and Agbowa respectively, at a significant level of  P<0.05 for male, female and combined sexes. The b values of 0.193 for Ijede and 0.165 for Agbowa were not significantly different (P> 0.05). The mean condition factors of 0.365 ±0.141 and 0.329±0.169 were obtained in Ijede and Agbowa, respectively. It was observed that the species in both lagoons exhibited negative allometric growth patterns with values 0.365 and 0.330 for Ijede and Agbowa lagoons respectively with no variations in the condition factors of both locations which indicate the need to assess human and domestic activities surrounding these water bodies.

The total 200 specimens of Catla catla and Cirrhinus mrigla were worked out during the two year study periods, from Dejla Dewada reservoir of Khargone district. Total length and body weight were estimated. The correlation coefficient (“r”) and ponder index (“Kn”) have also been computed. The result showed the growth of two IMC is satisfactory. The value of exponent ‘n’ in the equation W=cLn were 1.9416 and 1.4798 for Catla catla and Cirrhinus mrigla. The relative condition factor (“Kn”) remained greater than one fir both IMC indicating their good well being.

The Relationship

The African catfish (Clarias gariepinus) has been introduced several times to Indonesia, including from Thailand (Paiton strain). The breeding of Paiton strain resulted in albino individuals. The present study aimed to investigate the length-weight relationship, condition factor and biometric characteristic of those albinos. Five pairs of each albino and normal coloured Paiton African catfish were artificially bred. Larvae and juveniles from each pair were reared one month of larval rearing phase, one month of nursery phase and two months of grow-out phase, then the total length and body weight were measured for length-weight relationship and condition factor analysis, finally the biometric was characterized. The present study revealed that the relationship between total length (L) and body weight (W) of the Paiton African catfish was positive allometric (W = 0.0038L3.23 in the albino and W = 0.0027L3.27 in the normal coloured one). The albino Paiton African catfish was more rotund (condition factor of 0.79±0.07) than the normal colored one (condition factor of 0.68±0.06). Biometrically, the albino Paiton African catfish has a bigger head portion and fewer dorsal and anal fin rays than those of the normal coloured one. Despite the colour difference, the albino and normal coloured Paiton African catfish were morphologically different.

The response of Clarias gariepinus to Allium sativum on growth performance and as anti-bacterial agent in Staphylococcus aureus challenge infection was evaluated. A. sativum was included at 0% (control), 1.5%, 3.0%, and 4.5% in fish diet. Twenty fish samples each were randomly distributed into four tanks (T1, T2, T3 and T4). Fish were fed twice daily at 5% body weight for twelve weeks. All fish were challenged with 0.5ml of pure culture of S. aureus. A significant (P<0.05) increase in body weight, total length and standard length was observed. A. sativum at 3.0% inclusion promoted highest growth with feed conversion ratio (1.25-1.41), protein efficiency ratio (1.72-0.56), specific growth rate (1.92-2.09), condition factor (0.83-1.99) and survival rate (60-95). Fish-fed A. sativum diet showed that 4.5% inclusion had the least S. aureus activity. Bacteria load significantly (P<0.05) decrease at week 12. Culture water had dissolved oxygen of 4.0 - 4.2 mg/L, pH 6.0 - 7.0 and temperature of 26.0-28.0oC. This study has shown that A. sativum supplemented diets enhanced growth of C. gariepinus and functioned as antibacterial agent against S. aureus. A. sativum at 3.0% inclusion in diet is recommended for better fish growth and 4.5% A. sativum for antibacterial action. Keywords: Fish, herb, growth, infection

General Indicator

The condition factor is a parameter which acts as a general indicator of the "well-being" of a species, and it can be obtained through the analysis of width vs. weight relationships. The present work aims to investigate size vs. weight relationship and the condition factor of the crab Goniopsis cruentata (Latreille, 1803). The study area was the Mundaú/Manguaba estuarine complex, Maceió, state of Alagoas, Northeast Brazil. Samplings were monthly accomplished from August 2007 to July 2008. A total of 626 individuals were analyzed, being 309 males and 317 females. Males were larger and heavier than females, what is expected in many brachyuran. The growth was positive allometric to both males (b = 3.42) and females (b = 3.30), not obeying the "cube law". The condition factor of female was higher than that of male crabs, probably due to the gonad weight of females. It also varied seasonally for both sexes, being higher in the autumn and winter in males, and in the autumn and spring in females, and related to the molt and period of spawning intensification.

Biology of the spotted barb Barbodes binotatus (Valenciennes, 1842) in Barambai River, east Kalimantan is unknown. This study aimed to analyses sizes of fish, sex ratio, length-weight relationship and condition factor of the spotted barb. A total of 347 fish samples were collected by several gears in Barambai River from August to October 2017. The results of this research showed that the total length of the fish ranged from 45.67 to 146.01 mm and weight ranged from 1.27-43.34 g. The sex ratio of male and female were 1:1.12. The length-weight equations for males was W = 1x10-5 L3.063, W = 8x10-6L3.108 for females, and W = 9 x 10-6 L3.091 for both sexes. The condition factor (K) for the spotted barb was ranged between 0.826 – 2.214 with mean value of 1.163.  AbstrakBiologi ikan wader bintik dua Barbodes binotatus (Valenciennes, 1842) di Sungai Barambai, Kalimantan Timur belum diketahui.

The present study elucidated the length-weight relationship and condition factor of the Indian major carps catla Catla catla, rohu Labeo rohita and mrigala Cirrhinus mrigala from the Vallabhsagar Reservoir, Gujarat. The mean total lengths (TL) recorded for the three species during the study were, 40.734±0.614, 39.285±0.892 and 38.010±0.925 cm while mean weights (WT) recorded were 914.141±46.672, 969.306±93.738 and 635.714±51.129 g for catla, rohu and mrigal, respectively. The length and weight variables showed linear relationship as depicted by correlation coefficient (r) values of 0.987 in catla, 0.956 in rohu and 0.967 in mrigal. Growth in the three species was found to be positive allometric and exponent values (b) obtained were 3.104, 3.342 and 3.049 for catla, rohu and mrigal respectively. The condition factor (K) and relative condition factor (Kn) estimated revealed the well being of fish and conducive environment of the reservoir. Results of the study provided baseline information which would be helpful for the scientific management of Indian major carp fisheries in the Vallabhsagar Reservoir in Gujarat.
