“…This is supported by the research conducted by Benli et al (2008), which indicated that the Nile Tilapia (Oreochromis niloticus L.) exposed to ammonia has a form of cell changes as hydropic degeneration happens in liver cells. The liver becomes the main organ of various metabolic pathways.…”

One of the main problems in the waste management in Indonesia is the treatment of leachate, which mostly dumped to the river This research is aimed to obtain information of histological alteration in gills and liver of C. carpio L. exposed to leachate. Measurements on the water quality parameters comprised water temperature, pH, and dissolved oxygen (DO). This research was conducted by exposing leachate to C. carpio for 96 hours. The concentration of leachate were 0 ppm, 80 ppm, and 100 ppm. Histological preparation were made on the gills and liver using 10% fixative Neutral Buffered Formalin and Ehrlich Hematoxylin-Eosin staining with qualitative observation descriptive analyses for discussion. The result showed that increasing water temperature is directly proportional to the leachate concentration in the aquaria, while the value of pH and DO inversely proportional to the leachate concentration. Damages on the gills with 80 ppm leachate concentrasion were identified as follows: fusion of secondary gill filaments and hyperplasia of epithelial cell, along with karyorrhexis and hydropic degeneration on the liver. Damages on the gills of fishes exposed to leachate with 100 ppm concentrasion were identified as follows: fusion of secondary gill filaments, hyperplasia of epithelial cell, congestion, and edema along with karyorrhexis, hydropic degeneration and melanomacrophage centre (MMC) found on the liver. The results of this study can be used as an overview of the impact of an environmental pollution by leachate as indicated from histological damage to the gills and liver of C. carpio, thus contribute significan information to aquaculture sector and endorse better waste management

“…Toxic influence of chemicals in general occurs primarily in the liver. Ammonia can be carried away by bloodstream into the liver as nutrient and follow the metabolic pathways (Kucuk, 1999, in Benli et al, 2008. Ammonia and alkali are a strong indicator of toxicity in aquatic environments.…”

“…The ammonia values at 24 h of transportation (10-11 mg.L -1 ) were below the lethal concentration threshold for Nile tilapia juveniles (BENLI & KÜKSAL 2005). Tilapia juveniles tolerate high ammonia levels in the water (BENLI & KÜKSAL 2005, BENLI et al 2008.…”

This work evaluated the efficiency of clove oil as anaesthetic in handling and transportation of Nile tilapia, Oreochromis niloticus (Linnaeus, 1758). In the first experiment, safety concentrations of clove oil were assessed by measuring induction times to anaesthesia. The second experiment evaluated exposure times to anaesthetic. Clove oil efficiency during transportation was evaluated in a 24 h experiment using three concentrations of the anaesthetic (0, 9, and 18 mg.L-1). The most appropriate clove oil concentration to induce surgical anaesthesia was 90 mg.L-1. To biometry or other brief handling, the recommended concentration is 50-60 mg.L-1 as it provides fast recovery. Maximum anaesthesia time should be 10 min. The mortality rate of fish transported using 18 mg.L-1 of anaesthetic was significantly higher than that of the control group at 24 h of transportation and at 96 h after transportation. The fish transported using clove oil as anaesthetic presented more significant Na+ and K+ disorders as compared to the control group. As an anaesthetic, clove oil is efficient in the handling of Nile tilapia in routine fish hatchery procedures, although it should be avoided in the transportation

RESUMO:Alguns problemas relacionados à criação intensiva de peixes estão mais evidentes devido ao aumento da aquicultura em todo o mundo, destacando-se os distúrbios nutricionais e o aumento de doenças nos sistemas de produção. Com isso as pesquisas envolvendo produtos derivados de plantas vem ganhando espaço nessa área. A Hyptidendron canum é uma planta utilizada na medicina popular como antimalárica, anti-inflamatória, antiulcerativa e anti-hepatotóxica. Objetivou-se, neste trabalho, avaliar os efeitos celulares e teciduais do extrato etanólico bruto e das frações hexano, clorofórmio e acetato de etila da H. canum nas brânquias de Oreochromis niloticus L. Para isso, o extrato etanólico e as frações foram administrados no peixe através da ração. Após 24 horas da ingestão da ração, os peixes foram sacrificados e o segundo arco branquial de cada um foi processado histologicamente e corado com tricômico de Masson e Hematoxilina e Eosina (HE). Pela análise qualitativa das brânquias ao microscópio de luz, observou-se que o extrato bruto e as três frações promoveram, em diferentes intensidades nas lamelas, descamação e destacamento do epitélio respiratório, alteração da curvatura, desorganização do eixo, hiperplasia celular do tecido epitelial interlamelar e vasodilatação nas lamelas e no vaso central do filamento. Os resultados deste experimento mostraram que o extrato etanólico bruto e as três frações de H. canum promoveram processos inflamatórios e/ou lesões sistêmicas, dose dependente para O. niloticus. Palavras-chave:Cerrado, plantas medicinais, tilápia, toxicidade. ABSTRACT: Effect of the crude ethanol extract and fractions of Hyptidendron canum(Pohl ex Benth.) Harley on the gills of Oreochromis niloticus L. Some problems related to intensive fish farming are more evident because of the increased aquaculture worldwide, and we highlight the nutritional disorders and the increase of diseases in the production systems. Thus, research involving plant-derived products has been increasing in this area. The Hyptidendron canum is a plant used in folk medicine as an antimalarial, anti-inflammatory, anti-ulcer and antihepatotoxic agent. This study proposes to evaluate the cellular and tissue effects of the crude ethanol extract and the hexane, chloroform and ethyl acetate fractions of H. canum on the gills of Oreochromis niloticus L. The ethanol extract and fractions were administered through the feed of the fish. Twenty-four hours later, the fish were sacrificed and their second gill arch dissected. Histological analyses were performed using Masson's trichrome and Haematoxylin and Eosin (H&E). The qualitative analysis of the material showed that the crude extract and the three fractions caused varying degrees of peeling and detachment of the lamellar respiratory epithelium, alterations in the curvature and axis of the gill, cell hyperplasia in the interlamellar epithelium and lamellar vasodilation, as well as vasodilation in the central vessel of the filament. The results of this experiment showed that the crude ethanol...
