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).

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.

Weight Data

Ikan nila (Oreochromis niloticus) merupakan salah satu ikan introduksi yang mulai mendominansi hasil tangkapan ikan di Waduk Ir. H. Djuanda. Penelitian ini bertujuan untuk mengetahui hubungan panjang bobot dan menduga parameter pertumbuhan dari ikan nila di Waduk Ir. H. Djuanda. Contoh ikan didapatkan selama bulan Pebruari sampai Nopember 2008. Data panjang dan bobot ikan dianalisis hubungan panjang bobotnya dan ditentukan parameter pertumbuhannya dengan menggunakan program FISAT II. Hasil penelitian menunjukan bahwa pertumbuhan ikan nila di Waduk Ir. H. Djuanda bersifat allometrik negatif dengan persamaan W=0,129L2,4608,yang menandakan pertambahan bobotnya tidak secepat pertambahan panjangnya (b<3) dengan faktor kondisi 1,15.Ukuran panjang ikan yang tertangkap berkisar antara 11-41 cm. Hasil pendugaan parameter pertumbuhan diperoleh L=44,10 cm, K=0,72 (per tahun), dengan Z=2,4, M=1,34, F=1,06, dan E=0,44. Nile tilapia (Oreochromis niloticus) is one of introduction fishes that begin to dominate yield of fish capture at Ir. H. Djuanda Reservoir. The aim of this research was to know the length weight relationship and growth parameters estimation of nile tilapia at Ir. H. Djuanda Reservoir. The samples were collected during February until November 2008. The length and weight data of nile tilapia were analyzed its length weight relationship and the growth parameters were evaluated by FISAT II. The research shows that the characteristic of nile tilapia growth’s at Ir. H. Djuanda Reservoir was allometric negative with similarity W=0.129L2.4608, that indicated the increasing of weight from this fish not fast as its length (b<3) with the condition factor of it was 1.15. The range measure of fish length that captured was 11-41 cm. The results from growth parameters estimation were L=44.10 cm, K=0.72 (per year), with Z=2.4, M=1.34, F=1.06, and E=0,44.

Information related to the prevalence and intensity of para-sites in an aquatic environment is crucial as preventive and responsive efforts to manage aquatic resources, especially for fish farming pur-poses. Up to now, information related to the prevalence and intensity of ectoparasites on catfish from aquaculture ponds in Aceh Besar Dis-trict is rare. This study aims to investigate the prevalence, intensity, and dominance of ectoparasites on catfish from aquaculture ponds in Aceh Besar district. The total of 200 catfish from four research stations at Sibreh, Kareung, Lambaro, and Limpok was observed in this study. The ectoparasites observation was focused on the skin, fins, and gill of the catfish. The observation parameter consists of prevalence, in-tensity, domination, length-weight relationship, and condition factor. Identification result showed that there were four types of ectoparasites infect the catfish in the aquaculture ponds in Aceh Besar District i.e Trichodina sp., Gyrodactylus sp., Dactylogyrus sp. and Ichthyopthyri-us multifiliis. Station 3 (Lambaro) had the highest prevalence and in-tensity, which were 64% and 5.87 ectoparasites/fish, respectively. In-fected catfish tended to have a lower weight growth than healthy catfish.
