    FLOODPLAIN RIVER FOOD WEBS IN THE LOWER MEKONG BASIN A Dissertation by CHOULY OU Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Chair of Committee, Kirk O. Winemiller Committee Members, Masami Fujiwara Thomas D. Olszewski Daniel L. Roelke Head of Department, Michael Masser December 2013 Major Subject: Wildlife and Fisheries Sciences Copyright 2013 Chouly Ou ABSTRACT The Mekong River is one of the world’s most important rivers in terms of its size, economic importance, cultural significance, productivity, and biodiversity. The Mekong River’s fisheries and biodiversity are threatened by major hydropower development and over-exploitation. Knowledge of river food web ecology is essential for management of the impacts created by anthropogenic activities on plant and animal populations and ecosystems. In the present study, I surveyed four tropical rivers in Cambodia within the Mekong River Basin. I examined the basal production sources supporting fish biomass in the four rivers during the dry and wet seasons and explored the relationship between trophic position and body size of fish at various taxonomic levels, among local species assemblages, and across trophic guilds. I used stable isotopes of carbon and nitrogen to estimate fish trophic levels and the principal primary production sources supporting fishes. My study provides evidence that food web dynamics in tropical rivers undergo significant seasonal shifts and emphasizes that river food webs are altered by dams and flow regulation. Seston and benthic algae were the most important production sources supporting fish biomass during the dry season, and riparian macrophytes appeared to be the most important production source supporting fishes during the wet season.

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

SULAIMAN1 & R.L MAYDEN2 1Biological Science Programme, Faculty of Science, Universiti Brunei Darussalam, Tungku BE1410, Brunei Darussalam; E-mail:[email protected] 2Department of Biology, 3507 Laclede Ave, Saint Louis University, St Louis, Missouri 63103, USA; E-mail:[email protected] Abstract Borneo Island is governed by the countries of Brunei Darussalam, Malaysia (Sabah and Sarawak) and Indonesia (Kalimantan) and is part of Sundaland. These countries have a high diversity of freshwater fishes, especially described and undescribed species of Cypriniformes; together these species and other flora and fauna represent an extraordinary opportunity for worldwide collaboration to investigate the biodiversity, conservation, management and evolution of Borneo’s wildlife. Much of the fauna and flora of Borneo is under significant threat, warranting an immediate and swift international collaboration to rapidly inventory, describe, and conserve the diversity. The Sunda drainage appears to have been an important evolutionary centre for many fish groups, including cypriniforms (Cyprinidae, Balitoridae and Gyrinocheilidae); however, Northwestern Borneo (Brunei, Sabah and Sarawak) is not connected to Sundaland, and this disjunction likely explains the non-homogeneity of Bornean ichthyofauna. A previous study confirmed that northern Borneo, eastern Borneo and Sarawak shared a similar ichthyofauna, findings that support the general hypothesis for freshwater connections at one time between western Borneo and central Sumatra, and south Borneo and Java island.

Lumban Batu 1 Department of Aquaculture, Faculty of Agriculture, Lampung University, Bandar, Lampung, Indonesia; 2 Department of Aquatic Resources Management, Faculty of Fisheries and Marine Science, Bogor Agricultural University, Bogor, Indonesia; 3 Department of Aquaculture, Faculty of Fisheries and Marine Science, Bogor Agricultural University, Bogor, Indonesia. Corresponding author: I. G. Yudha, [email protected] Abstract. This study was conducted in April 2013 to March 2014 at Tulang Bawang River and Bawang Latak Swamp, Lampung, Indonesia. The aims of this study were to asses some reproductive aspects of L. ocellatus. The specimens were consisted of 690 males and 651 females. The results showed that sex ratio of L. ocellatus was 1:1 during the spawning period in October-January. This species was total spawner and they spawned annually in rainy season. The peak of breeding season was occured in November to December. The total length at first maturity of L. ocellatus are 157±1 mm (male) and 160 ±1 mm (female). The fecundity varied between 2.142-24.294 and had corellation with total length in equation as log F = 3,653 log L - 4,546 (Tulang Bawang River) and log F = 3,982 log L - 5,287 (Bawang Latak Swamp). Key Words: L. ocellatus, reproduction, GSI, fecundity, spawning period. Introduction. Labiobarbus ocellatus (Heckel, 1843) is a benthopelagic tropical freshwaters fish belonging to Cyprinidae family (Kottelat et al 1993; Roberts 1993; Froese & Pauly 2014), native to Peninsular Malaysia and the Greater Sunda Islands of Sumatra and Borneo (Weber & de Beaufort 1916; Kottelat et al 1993), also known as Bornean eye-spot silver shark in ornamental fish trading.

Nevertheless, controlled rearing is Accepted: March 22, 2021 currently rare due to the lack of knowledge on its food and feeding habits Online: April 26, 2021 besides other factors. Therefore, growth, food and feeding habits of S. mystus in _______________ Asejire Lake were investigated for six months (July to December, 2018). A Keywords: total of 105 specimens (86.00±14.30 g) were collected from fishers. Samples Nile Silver Catfish, were sexed and grouped according to sizes. Length-weight relationships (LWR) Schilbe mystus, and condition factor were assessed using standard procedures. Gut contents and Growth, niche breadth (Bi) were analyzed and quantified using a standard approach. In Feeding habit, addition, qualitative and quantitative variations in diet were determined Niche breadth, according to sex, size and seasons. Data were analyzed using descriptive Asejire Lake. statistics, chi-square and multiple linear regressions. The LWR indicated negative allometry growth with ‘b’ value of 2.87 and coefficient of determination (R2) of 0.85.
