“…There has not been much research published on CuSO 4 and LMB. A literature search found the following: (a) liver Cu concentrations and fish condition in reservoirs that had a long history of CuSO 4 treatment (Anderson, Giusti, & Taylor, ), (b) locomotor mechanisms and orientation in Cu‐polluted water (Timms, Kleerekoper, & Matis, ), and (c) determining Cu accumulation and oxygen consumption after Cu exposure (van Aardt & Hough, ). The search found one study by Skea and Simonin () that evaluated the Cu‐containing compound Cutrine® for use as an algaecide in fish culture; they determined that the 96‐hr LC50 value was 70 μL/L Cutrine® (6.4 mg/L Cu) in lake water with an alkalinity of 53 mg/L.…”

This study determined the effectiveness of copper sulfate (CuSO4) to inhibit fungal growth (caused by Saprolegnia spp.) on largemouth bass (LMB) eggs spawned on/in fiber mats in very high‐alkalinity/‐hardness waters; experiments also determined the toxicity of CuSO4 to LMB fry and juveniles. An untreated control and three CuSO4 concentrations (10, 20, and 40 mg/L) were tested under a flow‐through scenario in the effectiveness experiment. Eggs were treated daily until hatching began. Fungal load at the time of hatch had a total area > 3.0 cm2 in the untreated controls, total area 1.0 to <2.0 cm2 in the 10 and 20 mg/L CuSO4 treatments, and total area > 1.0 cm2 in the 40 mg/L CuSO4 treatments. Fungus samples were identified as Saprolegnia australis. The 24‐hr median lethal concentration (LC50) values on the LMB yolk‐sac and swim‐up fry were 32.0 and 4.6 mg/L CuSO4, respectively; the No Observed Effect Concentrations (NOEC) were 16.0 and 0.125 mg/L CuSO4, respectively. Juvenile LMB were extremely tolerant to CuSO4, and their 24‐hr LC50 value was 185.5 mg/L; the NOEC was 64 mg/L. This study indicates that CuSO4 can be an important resource for hatcheries to control egg fungus, especially in high‐alkalinity/‐hardness waters.

“…Once FK is incorporated into the feed, copper levels are markedly lower at 7.9–16.4 mg per kg of feed in the current study. Whilst feed intake rates were significantly reduced in Indian major carp ( Cirrhinus mrigala Hamilton) when exposed to 0.02, 0.10, 0.15 and 0.23 mg L −1 waterborne copper [ 63 ], no apparent negative effects, including copper accumulation, were noted in largemouth bass or common carp ( Cyprinus carpio ) exposed to high copper (290 μg·g −1 dry weight) in freshwater reservoirs [ 64 ]. Another negative effect of high levels of diet-borne Cu is lipid peroxidation in the internal organs [ 65 ].…”

A 10-week growth study was conducted to evaluate the effect of a natural gas fermentation bacterial meal (FeedKind®, FK) as a fishmeal (FM) alternative in largemouth bass (Micropterus salmoides) (48.0 ± 0.03 g). Four isonitrogenous and isoenergetic diets were formulated including one commercial control (C, 42% FM) and three experimental diets with gradient FK of 3% (FK3, 29%FM), 6% (FK6, 26%FM) and 9% (FK9, 23%FM), respectively. FK-fed groups showed significantly higher SR than that of C group. The WGR and SGR of fish fed FK3 and FK6 were significantly higher than those of FK9, but not statistical different from the C group. FK-fed groups showed higher apparent digestibility coefficients of dry matter and nutrients. Further, FK-fed groups increased the ratio of SOD/MDA in the plasma and liver, and the upregulation of intestinal Keap1 and downregulation of HIF1α was found in FK3. Furthermore, FK-fed groups showed higher microbial richness and diversity. Pearson correlation analysis found that antioxidant relevant biomarkers were negatively correlated with the relative abundance of certain potential beneficial bacteria. In conclusion, supplemented up to 3–6% FK replacing FM in a low FM diet of largemouth bass could increase growth, survival rate, antioxidant capacity, and improve gut microbiota.

“…The CF of C. carpio in the lotic habitat of Murrumbidgee River ranged from 1.32 to 1.36, and in lentic habitats of Lake Wyangan and Barren Box Swamp from 1.13 to 1.25 (Ada´mek, 2002). Botany Wetlands carp appear to be heavier than Murrumbidgee carp, but they are somewhat similar to carp in lakes of Southern California, as the CFs of C. carpio in Lake Mathews and Copper Basin Reservoir were 1.99 and 2.02 respectively (Anderson et al, 2001).…”

ABSTRACT1. In Australia, the carp Cyprinus carpio L. is regarded as a threat to the native fish and the aquatic environment. In recent years, Botany Wetlands, a significant coastal wetland in the Sydney region, has been invaded by the undesirable cyprinids, carp and goldfish (Carrasius auratus L.).2. In 1996 a cyprinid removal programme commenced at Botany Wetlands with the objective of managing the invasive species, increasing fish diversity, reducing cyanobacterial blooms and hence enhancing the aquatic habitat. Using electrofishing and gill netting, 4073 carp and 261 goldfish, amounting to 10 117 kg of cyprinid biomass were removed between 1996 and 2004. The captured carp ranged from 60 to 835 mm. Males matured before females. Carp between 350 and 680 mm in length grew at the rate of 1.66 AE 0.38 g day À1 .3. The success of the programme was monitored by assessing four indicators related to carp populations and two related to habitat. The former included the pattern of length-frequency distribution, mean weight per size class, condition factor (CF) and the catch per unit effort (CPUE), and the latter the Secchi disc transparency and cyanobacterial counts. After 8 yr of removal, the plots of carp length-frequency distribution flattened, CF decreased from 2.86 to 1.82 and CPUE decreased from 97 kg day À1 to 50 kg day À1 . A 10-fold decrease occurred in cyanobacterial counts and the Secchi disc transparency increased by 20%. More than 20 000 fingerlings of native Australian bass Macquaria novemaculeata (S.) have been introduced to the wetlands, increasing the potential for juvenile carp predation and biodiversity.
