Catfish farming is growing rapidly because the cultivation and marketing technology is relatively easy for the community to master, and the required business capital is relatively small. Pond water waste originating from fish metabolism and dissolved food waste is toxic to fish. One of the efforts that can be done is fish farming that is integrated with plants through an aquaponics system. Research to determine the effect of AB Mix addition on the growth of African catfish and lettuce cultivated by the aquaponics system. The research method used was an experimental method with a completely randomized design (CRD) consisting of three treatments and three replications. The addition of AB mixed nutrition did not differ in the growing significance of catfish and lettuce. However, the increase in growth occurred with an increasing dosage of AB mix with the best treatment with AB Mix 3 mL L-1. This treatment resulted in absolute growth in fish of 20.52 g and 4.62 g of watercress. The use of a dosage of AB mix higher than 3 mL L-1 may result in better growth.

The Relationship

This essay explores the evolving international relationship of the two national park agencies that in 1968 began to offer joint training classes for protected-area managers from around the world. Within the British settler societies that dominated nineteenth century park-making, the United States’ National Park Service (NPS) and Canada’s National Parks Branch were the most closely linked and most frequently cooperative. Contrary to campfire myths and nationalist narratives, however, the relationship was not a one-way flow of information and motivation from the US to Canada. Indeed, the latter boasted a park bureaucracy before the NPS was established. The relationship of the two nations’ park leaders in the half century leading up to 1968 demonstrates the complexity of defining the influences on park management and its diffusion from one country to another.

The purpose of this paper is to provide an overview of the differences in the strength of social capital that is bonding and bridging two community groups, namely land-dwellers and Sama Bajo boat-dwellers in three islands in Wakatobi Marine National Park. This study used a post-positivistic research paradigm, and the primary data were collected by using a questionnaire to 240 respondents who represented the group of land-dwellers and Sama Bajo boat-dwellers on the islands of Wangi-wangi, Kaledupa, and Tomia. This research was also supported by qualitative data through in-depth interviews from several informants and desk studies. The results showed that bridging social capital relations tend to be weak in the two forms of interactions between the Sama Bajo and the land-dwellers on Wangi-wangi Island and Kaledupa Island, while bridging social capital tend to be secured in Tomia Island. We found that the social context through the historical links in the past and identity played a role in the relationship of bridging social capital and bonding social capital in the three communities as an analytical unit of this research.

The objective of this research was to evaluate the supplementation of turmeric in the diet on antioxidant status and growth performance of African catfish (Clarias gariepinus) in zero water exchange condition. This study used a completely randomized design with 4 treatments and 4 replications. Each treatment consisted of feed supplementation turmeric at dosage of 0; 2.5; 5 or 7.5 g kg-1 diet. One hundred catfish juvenile (5.95±0.05 g) were stocked in intermediate bulk container (IBC) tank (1×1×1 m3) and rearing in zero water exchange condition for 60 days. Catfish were fed at satiation twice a day, in the morning and evening. The results showed that an increase in antioxidant content in catfish fed with the addition of turmeric, which simultaneously also reduced the percentage of liver damage. The parameters of liver damage can be seen from several parameters i.e. pale liver, droplet fat and fat content in the addition of turmeric treatment is lower than without the addition of turmeric. However, catfish fed with the addition of turmeric did not show significant results in terms of growth performances.

ABSTRACTThe research was conducted at the Aquaculture Laboratory, University of Lampung in May to July,  2018. The aim of this study is to determine the effect of substitution of fish meal with catfish head flour on the growth of catfish, and head flour dosage the best for catfish growth. The study used a Completely Randomized Design with 3 treatments and 3 replications A (100% fish meal), B (70% fish meal and 30% catfish flour), and C (40% fish meal and 60% catfish flour). Parameters observed included absolute growth, daily growth rate, protein retention, feed convertion ratio (FCR), survival rate (SR), and supporting parameters that is feed cost and water quality. The data obtained were analyzed by variance and continued with smallest real difference test with a 95% confidence level. The results showed that the proportion of catfish head flour in artificial feed had an effect on absolute weight growth and daily growth rate (P, 0.001). The proportion of the use of 30% starch in the feed of catfish has a real influence on absolute growth (40.25 ± 5.67 g), and daily growth rate (0.67 ± 0.09 g/day).Keywords : Catfish, catfish head waste, substitution, feed, growth

The Relationship

The effects of two silvicultural herbicides (Vision®, Release®) on bryophytes and lichens were studied in a harvested boreal mixedwood ecosystem. A completely randomized design with 115 plots of 1 m2 allowed direct comparison between herbicides and their effects on community dynamics. Regression models were used to analyze the relationship between herbicide application rates (0.71-6.72 kg active ingredient/ha) and changes in bryophyte and lichen abundance and species richness for 2 years following herbicide application. Results showed that bryophyte and lichen abundance and species richness decreased after herbicide treatments. In general, herbicide applications reduced the diversity of forest mesophytes and weedy colonizers to an ecosystem with only a few species of colonizers. A combination of clustering techniques and ANOVA were used to divide bryophytes and lichens into three ecologically defined response groups: herbicide-tolerant colonizers, semi tolerant long-term stayers from dry open forest, and sensitive forest mesophytes.
