However, diseases affecting aquaculture and economic losses are worldwide problems and it needs low cost, sustainable, highly efficient, specific and eco-friendly therapeutants. Due to the rising up antibiotic resistant-microorganism, bacteriophage therapy has reinvigorated to replace antibiotics in agriculture, medicine, food safety and the environment. Likewise, it also holds great promise to avoid, control and treat bacteria in aquaculture to decrease the mortality level of different aquatic animal diseases. The isolation and characterization of new phages and phage application therapy to eliminate bacterial fish and shellfish pathogens such as Vibrio, Aeromonas, Pseudomonas, Lactococcus, Yersinia, Flavobacterium, and Streptococcus was gradually reported in aquaculture literature. The present review summarizes large-scale reports in vitro or in vivo use of aquaphage studies and applications in fish diseases from the 1980s to 2022 and future directions.","PeriodicalId":14704,"journal":{"name":"Israeli Journal of Aquaculture-bamidgeh","volume":"36 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73995515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meagre fillets were treated with ozone for 15 (O-15) and 30 (O-30) minutes and vacuum-packed and stored at +2 °C for 12 days. Control group (C) was not treated with ozone and stored after vacuum packaging. For microbiological changes, Total Mesophilic Aerobic Bacteria (TMAB), Pseudomonas sp., Lactic Acid Bacteria (LAB) and Total Psychrophilic Aerobic Bacteria (TPAB) counts were analyzed. At the end of storage, the highest bacterial counts were found in group C (>7.00 log cfu/g). In ozone-treated samples, Pseudomonas sp. counts did not exceed 7.00 log cfu/g only in the O-30 group. In the sensory evaluation of the samples, it was determined that the total demerit points were 18 points for group C, 16.25 points for O-15 and 14.75 points for O-30 at the end of storage over 30. No significant change was found according to the color results of the samples, but at the end of storage, it was observed that the L value of the ozone-treated samples was higher and the samples had a lighter color. In the conclusion of the results, it was observed that ozone treatment prolonged the shelf life of vacuum-packed meagre fillets for 4 days for the O-30 group compared to control and O-15 group without causing the sensory and color loss.","PeriodicalId":14704,"journal":{"name":"Israeli Journal of Aquaculture-bamidgeh","volume":"54 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88408591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to investigate their functions in turbot (Scophthalmus maximus) response to the Vibro anguillarum challenge. SmMnSOD, the full-length liver cDNA of MnSOD from S. maximus, was cloned by fast amplification of cDNA ends (RACE). Sequencing of nucleotides indicated that the SmMnSOD cDNA was 1267 base pairs with a 684-base-pair open reading frame, encoding a 228 amino acid protein with 28 amino acid residues. The SmMnSOD sequence contains MnSOD signatures (DVWEHAYY) and probable N-glycosylation sites (NVT, NHT, and NLS). The deduced sequence of SmMnSOD revealed sequence homology between 85.3% and 92.9% with those of other species. A phylogenetic study found that SmMnSOD clustered with other fish MnSOD, indicating that SmMnSOD was a member of the MnSOD family. The SmMnSOD transcript was discovered by qRT-PCR in the gill, stomach, head-kidney, muscle, liver, intestine, and heart of S. maximus, with the highest expression in the liver. Upon intervention by V. anguillarum, the liver and head kidney transcript levels of SmMnSOD were up-regulated at 12 and 48 h, whereas the temporal expression profiles of the CAT transcript increased at 6 and 24 h. As the pathogenic bacterial stress processing was prolonged to 72 h, the liver and head kidney transcript levels of SmMnSOD and CAT decreased gradually. Thus, SmMnSOD was triggered and may be related to S. maximus’ immunological responses against V. anguillarum.","PeriodicalId":14704,"journal":{"name":"Israeli Journal of Aquaculture-bamidgeh","volume":"192 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72419772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In-vitro screening, the extracts of ten herbs were conducted to test the inhibition ability against Vibrio parahaemolyticus, causing acute hepatopancreatic necrosis disease. The results showed that five out of ten herbal species, including Pithecellobium dulce, Melaleuca leucadendron, Eucalyptus globulus, Mimosa pirga, and Hibiscus sabdariffa displayed potent antibacterial activity. Besides, three types of extracts of H. sabdariffa, E. globulus, and M. pirga were coated to the pellet feed at a concentration of 1%. After 30 days of feeding, the whiteleg shrimp (Penaeus vannamei) were challenged by V. parahaemolyticus through immersion. The growth performance (such as growth rate in length and weight, survival rate), hematological parameters of total hemocytes (THC), hyaline hemocytes (HC), and granulocytes (GC), and hepatopancreas recovery under the treatments with herbal extracts of the whiteleg shrimp were significantly enhanced as compared with the control (without herbal extract). The mortality and the bacterial density in the hepatopancreas of shrimp decreased. Specifically, the mortality of shrimp in the treatment supplemented with the methanol extract of H. sabdariffa was the lowest, followed by M. pirga and E. globulus. The experimental results also indicated that H. sabdariffa, E. globulus, and M. pirga could improve immune parameters and disease resistance; therefore, they should be employed in sustainable shrimp, practical farming.","PeriodicalId":14704,"journal":{"name":"Israeli Journal of Aquaculture-bamidgeh","volume":"46 30 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88702231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kargin","doi":"10.46989/001c.81127","DOIUrl":"https://doi.org/10.46989/001c.81127","url":null,"abstract":"Phytoplankton species preferred in marine fish farming are the primary food source in the larval and young stages of bivalve mollusks, along with some fish and shellfish larvae. For this reason, selecting the appropriate phytoplankton and production technique for feeding marine fish larvae is crucial. Nannochloripsis oculata microalgae species, widely used in rearing sea bream and sea bass larvae and feeding rotifers, has an essential place in our country. N. oculata microalgae species, which is used in rearing sea bream and sea bass larvae and feeding rotifers, was produced in a helical photobioreactor by applying a continuous production technique at 30 ‰ salinity, and its growth performance was aimed to be investigated. In the study, N. oculata was grown in a helical photobioreactor at 30‰ salinity by applying the continuous production technique for two weeks, and the daily cell number and specific growth rate were determined. The study was repeated three times. The supply of live feed for marine fish fry and hatcheries established for this purpose is one of the most critical problems. The latest technology in the production of microalgae, which is the primary link of the live feed chain in this sector, is continuous algae production in helical tubular reactors. The helical tubular reactor used in the study consists of a transparent hose system consisting of a completely tubular helical reactor designed for microalgae production. The helical tubular continuous production system offers more efficient and economically more convenient alternatives than existing production systems. One of the most essential advantages of this system is that the system can be designed without requiring significant capital. The continuous culture technique allows the application of long-term and safe algae cultures. With this system, besides providing continuity in production, the negativities in batch production can be eliminated with adequate light. Since the algae production with the continuous method in the spiral photobioreactor remains in the maximum growth phase for a longer time than the batch production, it is a system with high production efficiency and quality, and production capacity is guaranteed. In addition, the algae product harvesting in the continuous system ensures the daily harvesting of algae as much as half of the system volume. A helical reactor enables automation in algae production and high-quality production over long periods. In the study, the sowing density of N. oculata was determined as 1.068x106 ±0.006 cells/mL. Algin cell growth increased logarithmically during the first five days. From the 5th day to the 15th day, the increase in the number of cells was determined as 12.35x106±0.165 cells/mL at the highest and 8.76x106±0.709 cells/mL at the lowest. However, on the 13th day, it was determined that the increase in algin cells was 12.35x106±0.165 cells/mL, and the specific growth rate decreased by 0.189±0.016 divisions/day.

The workshop offered an opportunity to bring diverse stakeholders together to facilitate a dialogue on issues regarding aquaculture in Hawai‘i and to build relationships to promote future collaborations. Topics of discussion included food safety and security - sustaining local communities by enhancing locally produced and consumed foods; stimulating job creation while conserving natural and cultural resources, existing and future aquaculture projects, considerations for project siting and national aquaculture policies. A Workshop Advisory Team (WAT) was formed to plan the workshop and was comprised of cultural advisors, community and stakeholder representatives, and state and federal agency representatives. The WAT identified a workshop process, content, and potential participants. The workshop was the first of a series of planned discussions and brought together cultural and fishpond practitioners, community members, farmers, business and food industry representatives, subject matter experts, state and federal agency representatives and marine resource managers. The first day of the workshop was an information-sharing day open to the public. The format included presentations and panel discussions with opportunities for questions and answers. Presentations were provided on topics including: • Historical context of aquaculture in Hawai‘i • Current aquaculture activities in Hawai‘i • A national perspective of aquaculture • The role of the Department of Land and Natural Resources in the oversight of aquaculture in the State of Hawai‘i. Panel discussions included: Native Hawaiian aquaculture practices; today’s open ocean aquaculture; and cultural and environmental considerations in aquaculture practices. The remaining two days of the workshop focused on identifying common ground among the diverse participants to stimulate value-based discussions among multiple stakeholder groups. The remainder of the workshop focused on the Appreciative Inquiry (AI) strategic planning process for invited participants. Appreciate Inquiry is a process that identifies areas of common ground within a diverse group and is highly effective in stimulating discussions based on shared values among multiple stakeholders through a series of iterative and interactive sessions.
