Tinfoil barb (Barbonymus schwanenfeldii) is one of the potential local fish to be cultivated as a food or pet fish. The data and information of the growth pattern of species are essential for fish farming success. The observation on the length and weight relationship is an usefull indicator to determine the pattern of growth fish observed. This study aims to determine the growth patterns of tinfoil barb fish based on length and weight relationship, condition factor and fish fecundity of tinfoil barb from Sarolangun, Jambi and Anjongan, West Kalimantan. The 30 samples were taken randomly from each group. Data were analyzed using analysis regression Microsoft Excel. The result showed that the regression coefficient of length and weight relationship was 2.811 for Sarolangun and 2.686 for Anjongan. The regression value indicates that the the growth of tinfoil barb was allometric negative, with an average factor condition ranged from 0.99 to 1.002. Length and weight relationship had determinant value (R2) ranged from 0.79 to 0.96, with the fecundity ranged from 20168 to 232.040 eggs from 9–45.5g of gonad weight.

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.

This study aimed to provide information about the population structure and somatic index of Hypostomus cf. ancistroides collected from the Bonito river, located in the Ivaí river basin. The length-weight relationship was isometric for both the sexes. The length structure analysis showed that the larger individuals (from 18.1cm to 27.0cm in length) predominated, and the lowest abundances occurred at the size extremes (9.1-12cm and 27.1-30.0cm). The reproduction period occured between October and January for the females and between November and January for the males. The liver somatic index cannot be used as an indicator of the reproduction period in either of the sexes, due to no correlation between the liver somatic index and the gonad somatic index. The gonad weight exerted no influence on the monthly mean condition factor and the correlation between the condition factor and gonad somatic index was high. The condition factor could be an indicator of the reproduction period of this species.

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.
