“…For example, a previous study found that the slc26a6 gene of the nakedcarp (Gymnocypris przewalskii) was expressed in various tissues, such as gills, liver, kidneys and intestines, and that the upregulation of SLC26A6 increased HCO3 − secretion and the Cl − absorption in the cells (Ping et al, 2015). Notably, several studies have shown that elevated chloride concentrations in the aquatic environment reduce the toxic effects of nitrite on aquatic animals, because both nitrite ions and chloride ions compete for the same site of active transport (Alcaraz and Espina, 1994;Jiann-Chu and Lee, 1997;Sha-Yen and Chen, 1998;Yildiz and Benli, 2004;Kozák et al, 2005;Camargo and Alonso, 2006;Alonso and Camargo, 2008;Zhang et al, 2015). Therefore, we hypothesized that the upregulation of SLC26A6 in nitrite-tolerant shrimp increases the absorption of chloride ions, forcing chloride ions and nitrite ions compete for the same site of active transport on the plasma membrane and various organelle membranes, resulting in enhanced nitrite tolerance.…”

Nitrite is a major environmental toxin in aquaculture systems that disrupts multiple physiological functions in aquatic animals. Although nitrite tolerance in shrimp is closely related to successful industrial production, few genetic studies of this trait are available. In this study, we constructed a high-density genetic map of Litopenaeus vannamei with 17,242 single nucleotide polymorphism markers spanning 6,828.06 centimorgans (cM), with an average distance of 0.4 cM between adjacent markers on 44 linkage groups (LGs). Using this genetic map, we identified two markers associated with nitrite tolerance. We then sequenced the transcriptomes of the most nitrite-tolerant and nitritesensitive individuals from each of four genetically distinct L. vannamei families (LV-I-4). We found 2,002, 1,983, 1,954, and 1,867 differentially expressed genes in families LV-1, LV-2, LV-3, and LV-4, respectively. By integrating QTL and transcriptomics analyses, we identified a candidate gene associated with nitrite tolerance. This gene was annotated as solute carrier family 26 member 6 (SLC26A6). RNA interference (RNAi) analysis demonstrated that SLC26A6 was critical for nitrite tolerance in L. vannamei. The present study increases our understanding of the molecular mechanisms underlying nitrite tolerance in shrimp and provides a basis for molecular-marker-assisted shrimp breeding.

The feed plays a critical role in the success of freshwater lobster cultivation. Still, it often presents challenges due to its relatively high cost, accounting for up to 60% of production expenses. To address this issue, farmers in Sukabumi have devised various alternative feeds by harnessing different protein sources to reduce the expenditure on commercial pellets. One such innovation is a moist feed composed of a blend of pellets, cassava, and snails in a ratio of 1:1:1.4. However, there has yet to be prior testing of its nutritional content. Consequently, this study aims to evaluate the nutritional composition of this moist feed and assess its impact on the growth of freshwater lobsters and water quality. For this research, 100 lobsters ranging in size from 7 to 10 grams, were reared in fiberglass tanks. The lobsters were fed twice daily. The proximate analysis of the cassava and snail-based moist feed revealed protein content (20.52%), fat (2.61%), carbohydrates (12.87%), moisture content (50.64%), and ash content (13.36%). The lobsters exhibited a growth rate of 0.3% per day, and the water quality remained favorable, with parameters such as temperature (23-25°C), pH (6.5-7), dissolved oxygen (5-7 mg/L), nitrate (1.907 mg/L), nitrite (0.141 mg/L), ammonia (0.442 mg/L), phosphate (0.032 mg/L), and alkalinity (237.4 mg CaCO3/L) within acceptable ranges. These findings suggest that the moist feed provided by farmers lacks sufficient protein content to fully meet the nutritional requirements of lobsters, resulting in slower growth. On the other hand, water quality remains conducive for successful lobster farming.

Although the noble crayfish (Astacus astacus L.) and stone crayfish (Austropotamobius torrentium Schr.) are critically endangered European species, their water quality requirements are not sufficiently known. This study aimed to investigate the physico‐chemical tolerance range of the noble and stone crayfish in the Czech Republic compared with those of the invasive spiny‐cheek crayfish (Orconectes limosus Raf.). At 1008 sites with crayfish either absent or present, the following 18 physico‐chemical variables were investigated: dissolved oxygen, pH, BOD5, CODCr, ammonia, ammonium ions, nitrite, nitrate ions, zinc, copper, iron, aluminium, calcium, sulphates, chlorides, total phosphorus, suspended solids, and conductivity. For the noble and stone crayfish, only minor differences in water quality were found. This indicates that the water quality requirements of these indigenous crayfish are likely to be very similar. However, significant differences in water quality were observed between locations inhabited by indigenous crayfish and those inhabited by the invasive spiny‐cheek crayfish. Based on these findings, we hypothesize that the invasive species is able to survive in locations with lower water quality. Simple logistic regression models were then used to examine relationships between the presence or absence of noble crayfish and each evaluated water quality variable. The presence of this species was related significantly with those variables that indicate nutrient enrichment (particularly ammonium, BOD5, and nitrite) and to iron. Overall, although the indigenous crayfish species were found at several sampling sites that had impaired water quality, the statistical analyses indicate that the indigenous species require water of high quality. Improvement in water quality is therefore an important step in sustaining indigenous crayfish populations. Copyright © 2012 John Wiley & Sons, Ltd.
