Introduction: The endemic fishes of the ancient lakes of Sulawesi are under increasing threat. Objective: To evaluate the data and information available from a holistic management perspective and to formu- late measures to conserve the endemic ricefish Oryzias nigrimas in Poso Lake, Indonesia. Methods: Collection of primary data from three stations around Lake Poso and literature study. Results: Threats to O. nigrimas include habitat degradation and loss, introduced alien species, and exploitation as a locally important food fish. Options to promote sustainable fisheries management include spatial and temporal limitations to minimise catch of gravid or brooding fish. Habitat protection should include measures to minimise impacts from activities which can reduce water quality and disturb or kill aquatic vegetation. Conclusion: Measures to prevent further O. nigrimas population decline are considered urgent and further research is recommended to fill identified knowledge gaps. Ex-situ conservation, including the development of captive breeding, could also contribute to a holistic O. nigrimas conservation strategy. Key words: endemism; lacustrine; Oryziinae; black buntingi; invasive species; light fishing. Serdiati, N., Arfiati, D., Widodo, M.S., Lelono, T.D., Ndobe, S., Mansyur, K., & Moore, A.M. (2021).

    Sex Differences in Visual Perception in Melanochromis Auratus

    SEX DIFFERENCES IN VISUAL PERCEPTION IN MELANOCHROMIS AURATUS Margaret Coniam A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE August 2014 Committee: Moira van Staaden, Advisor Sheryl Coombs Robert Huber ii ABSTRACT Moira van Staaden, Advisor The cichlid fishes of Lake Malawi have undergone explosive speciation in the past 1.5 million years with the production of between 500-1000 species of cichlid 1. Sensory factors such as visual, olfactory and acoustic signals are all believed to play a role in this differentiation process. Vision is by far the most studied and best understood of the sensory modalities, but there is a distinct gap between our understanding of the molecular components of the cichlid visual system and whether, or how exactly, these impact the behavior displayed. Recent research has shown that the type of visual pigment expressed in the retina differs by sex in Melanochromis auratus 11. We aimed to determine whether such differences are reflected in sex- dependent variation in hue sensitivity and hue discrimination in M. auratus. To test this, we used a modified optomotor discrimination task to assess (i) differences in the luminance curves for each sex and (ii) sex differences in the minimum angular distance of adjacent hues required to elicit recognition as two distinct stimuli. Our results indicate significant variation in the minimum brightness required for the perception of hues across the color spectrum, but no sex- specific difference in detection thresholds. Similarly, results for the minimum angular distance required to discriminate between adjacent hues suggest there are areas of the color spectrum to which vision is tuned, but again no difference between the sexes.

This task force was originally named KIP-HAM in 1996. As a commission whose work was to monitor Human Rights issues, KIP-HAM received many reports and inputs from the community, both victims’ community and others who dared to express their aspiration regarding human rights issues that took place in their regions. In the beginning, KIP-HAM only received reports through phone communication but the public gradually grew brave in delivering their reports directly to KIP-HAM secretariat. In several meetings with victims’ community, there was an idea to form an entity that deals specifically with cases of forced disappearances as a response to continuous violent practices that had claimed many victims. The idea was thrown in by one of the victims’ mothers named Ibu Tuti Koto. It was finally agreed that a commission would be established to deal with cases of disappearances and victims of violence under the name of Kontras.

Received: October 9, 2013; Accepted: January 21, 2014 Abstract We report 69 fish species in 34 teleost families nearly all collected during a preliminary survey of the Sungai Pohara and coastal localities in Sulawesi Tenggara, including Muna Island, in June 2010. Of these species, nine are introduced or exotic and another is questionably native. The family Gobiidae is the most diverse taxon, represented by 14 native species. Atherinomorph fishes of the family Adrianichthyidae are represented in the province by four endemic species and two others that are widespread, all in the genus Oryzias. This fish fauna contrasts sharply with the riverine ichthyo- fauna of the adjacent Sulawesi Tenggara islands of Buton and Kabaena in which there are reportedly no ricefishes and few endemics. New species are being described by the field team and collaborators. Our ultimate goal is to discover, describe, highlight, understand and encourage the conservation of the native freshwater and coastal fish biota of Sula- wesi.

  • Genetic Resources for Aquaculture: Status and Trends

    Genetic Resources for Aquaculture: Status and Trends

    109 Genetic resources for aquaculture: status and trends Roger S.V. Pullin 7A Legaspi Park View, 134 Legaspi Street, Consultant, Philippines 1. SUMMARY Aquaculture, the farming of aquatic plants and animals, has grown consistently since 1970, when it provided only 3.9 percent of world fish supply. In 2004, global production of farmed fish (mainly crustaceans, molluscs and finfish) was over 45 million tonnes, comprising about 32 percent of total world fish supply, while the total production of farmed seaweeds for food and extraction of chemicals, was about 13.9 million t. Aquaculture also provides increasing proportions of the world’s supply of ornamental aquatic organisms. Over 90 percent of aquaculture takes place in developing countries, where it has high importance for poor people in terms of nutrition and livelihoods and where further responsible development of aquaculture, integrated with other natural resource use, has high potential for future growth. Based upon statistics submitted to FAO by its member States, about 84 percent of farmed fish production comes from Asia, with 67 percent coming from the Peoples’ Republic of China. However, aquaculture is increasing in importance in all developing regions and is expected to provide about 50 percent of world food fish supply within the next 20 years. The future of aquaculture will depend in large measure upon the effective management of the genetic resources for farmed aquatic plants (PGR) and farmed fish (FiGR), as well as those for the organisms that provide their food and ecosystem services. Fish farms are agroecosystems and aquatic genetic resources for aquaculture on farms are part of agrobiodiversity.

    Phylogenetic and taxonomic studies of the medaka Title (Beloniformes, Adrianichthyidae) endemic to Sulawesi, Indonesia( Digest_要約 ) Author(s) Mokodongan, Daniel Frikli Citation Issue Date 2016-09 URL http://hdl.handle.net/20.500.12000/35389 Rights Abstract Although the family Adrianichthyidae is broadly distributed throughout East and Southeast Asia, 19 endemic species are distributed in Sulawesi, which is an island in Wallacea. However, it remains unclear how Adrianichthyidae biodiversity hotspot was shaped. Moreover, seven of the 19 endemic species were described within this decade, suggesting that we still do not know the full picture of the biodiversity of this family in this small island ofthe Indo-Australian Archipelago. First, I reconstructed molecular phylogenies for the Sulawesi adrianichthyids and estimated the divergence times of major lineages to infer the detailed history of their origin and subsequent intra-island diversification. The mitochondrial and nuclear phylogenies revealed that Sulawesi adrianichthyids are monophyletic, which indicates that they diverged from a single common ancestor. Species in the earliest branching lineages are currently distributed in the central and southeastern parts of Sulawesi, indicating that the common ancestor colonized Sula Spur, which is a large promontory that projects from the Australian continental margin, from Asia by tectonic dispersal c.a. 20 Mya. The first diversification event on Sulawesi, the split of the genus Adrianichthys, occurred c.a. 16 Mya, and resulted in the nesting of the genus Adrianichthys within Oryzias. Strong geographic structure was evident in the phylogeny; many species in the lineages branching off early are riverine and widely distributed in the southeastern and southwestern arms of Sulawesi, which suggests that oversea dispersal between tectonic subdivisions of this island during the late Miocene (7-5 Mya) contributed to the distributions and diversification of the early branching lineages.

The treatment is the concentration of the use of nilem skin gelatin 0.2%, 0.3%, 0.4%, and CMC 0.4% (control) of the total mixture of ice cream ingredients (full cream milk powder, skim, stabilizer, emulsifier, and water) with 4 repetitions. The parameters observed were the level of preference for the color, aroma, texture, and taste of ice cream. The most preferred ice cream is obtained by using nilem skin gelatin at a concentration of 0.4%.

INTRODUCTION Nilem is a family of Cyprinidea freshwater fish, and can be seen in Figure 1. Cultivation of nilem fish is almost abandoned because its utilization is not optimal [25]. The part of nilem fish which is eggs is generally used to make caviar so that there is fish skin waste. To maximize the utilization of nilem fish, it is necessary to diversify through processing nilem skin gelatin. Nilem fish's skin is one of the potential wastes to be the basic
