The effects of temperatures (22, 26, 30 and 34 °C) diets (commercial pellet shrimp) on the growth properties gastric emptying time (GET) tiger grouper × giant (TGGG) hybrid were analyzed over a day experimental period under controlled laboratory conditions. Food consumption (FC), food conversion rate (FCR), specific (SGR) GET significantly influenced by temperature diet type. highest mean SGR (1.00% BM day−1, p < 0.05) was observed in °C + shrimp group fish, while lowest 22 (0.59% day−1). No...

A global interest in Silver Barb (Barbonymus gonionotus) cultivation has arisen because of a combination declining wild stock and steady increase demand market value. The purpose the current investigation was to evaluate impact extreme water temperature changes on growth, hemato-biochemical responses, pepsin enzyme activity gill histomorphology B. gonionotus. Four distinct temperatures (22, 26, 30 34 °C) were applied laboratory triplicate glass aquariums (150 L each). At 22 °C, respectively,...

Although fish is a significant source of protein, they are currently affected by rapid industrialization and mechanized agricultural activities, resulting in increased concentrations heavy metals fishes. Concentrations metals, namely, Cd, Cu, Mn, Zn, were estimated the muscle, liver, gills two commercially important marine fishes, Arius thalassinus Johnius belangeri. The samples collected from Kapar Mersing, which west east coastal waters Peninsular Malaysia, respectively. results showed...

An integrated experiment was performed on juvenile Malabar blood snapper (Lutjanus malabaricus) to investigate the effect of temperature and diet in their pepsin activities relation with digestive somatic index (IDS) relative gut length (RGL). One hundred twenty L. malabaricus (13–15 cm) were equally distributed among four exposed treatments (22, 26, 30 34 °C) representing seasonal range account for end century predicted temperatures, two diets as commercial pellet natural shrimp. After 7...

The growth, gastric emptying time (GET), and oxygen consumption rate (OCR) of the commercially important freshwater mahseer, Tor tambroides, were evaluated under five temperatures (22 °C, 24 26 28 30 °C) in triplicates with 15 fish per replication a controlled laboratory condition. After 12 weeks, body weight gain (BWG), specific growth (SGR), daily (DGR) measured. highest BWG (7.25 ± 1.14 g), SGR (0.71% 0.10% day−1), DGR (4.70 0.20 g day−1) observed at whereas lowest (3.16 0.90 (0.30 0.05%...

Cymbopogon citratus (C. citratus) has antioxidant, anti-inflammatory, and chemoprotective properties. This study was conducted to evaluate the protective effect of C. aqueous extract against hydrogen peroxide (H2O2)–induced oxidative stress injury in reproductive system male rats. The twenty-five rats used this were divided into five groups, comprised each. control group received standard food drink. H2O2 water with 0.5% H2O2. + vitamin E food, H2O2, [100 mg·kg−1 body weight (bw)], or as an...

Length-weight and length-length relationships are presented for four fish species from the estuaries of south Johore, Peninsular Malaysia.The values exponent b in length-weight (LWRs) W= aL ranged 2.97 to 3.44 (LLRs) TL= aSL 0.87 0.95.The application these regressions should be limited observed length ranges.The condition factor K was judged less important comparative studies, since this parameter closely correlated with b.To our knowledge herein both archer (Toxotes chatareus Toxotes...

Global climate change is impacting and will continue to impact on marine estuarine fish fisheries. Data trends show effects ranging from growth, digestion physiology performance in freshwater ecosystems. The present study was designed develop a concept for cause effect understanding with respect climate-induced temperature salinity changes explain ecological findings based physiological processes. wide comparison of species. preliminary conclusion can be drawn that warming shift distribution...

The effects of two waste sources, red hybrid tilapia (Oreochromis sp.) and whiteleg shrimp (Litopenaeus vannamei), drying methods (freeze-drying oven-drying) on the proximate chemical composition bioflocs were investigated. In total, four kinds experimentally treated compared to identify best source method produce biofloc an acceptable nutrient value: freeze-dried (FDSBF), oven-dried (ODSBF), (FDTBF), (ODTBF). protein, lipid, ash, fiber, total nitrogen free extract (NFE), energy contents...

This systematic review aimed to synthesise the existing studies regarding effects of ocean acidification (OA) on seaweed aquaculture. Ocean scenarios may increase productivity aquacultured seaweeds, but this depends species-specific tolerance ranges. Conversely, be reduced, with ensuing economic losses. We specifically addressed questions on: how seaweeds acclimatise an in oceanic CO2; OA photosynthetic rates and nutrient uptake; knowledge gaps mitigation measures for farming environments....

Wild stocks of endangered mrigal carp, Cirrhinus cirrhosus (Bloch 1795), continues to decline rapidly in the Indo-Ganges river basin.With an objective evaluate its population status, landmark-based morphometric and meristic variations among three different viz., hatchery (Jessore), baor (Gopalganj) (Faridpur) Bangladesh were studied.Significant differences observed 10 15 measurements head length, standard fork length base spinous, pre-orbital eye post-orbital upper jaw, height pelvic fin...

Hybrid grouper (Epinephelus fuscoguttatus [TG] × E. lanceolatus [GG]) juveniles were evaluated in terms of their blood hematology and biochemical levels after 60 days exposure to different temperatures (22 °C, 26 30 34 °C) triplicate (20 fish/tank; body weight 200 ± 15 g; length 22.5 1 cm). The fish fed daily with commercial pellets (42% protein, 9% ash, 11% lipid) or shrimp lipid). Results showed that the hematologic parameters at °C significantly better than those other temperatures....
