{"title":"The results of breeding the seaside scallop in a bottom aviary combining bottom and suspended methods of cultivation","authors":"Elena Brovkina, Elena Kostina","doi":"10.37663/0131-6184-2023-5-67-72","DOIUrl":"https://doi.org/10.37663/0131-6184-2023-5-67-72","url":null,"abstract":"The cultivation of bivalves is currently one of the most promising areas of mariculture worldwide. The article discusses the advantages and disadvantages of traditional methods of cultivating scallop seaside, where the suspended method is considered more promising than the bottom. The specific productivity of cage cultivation is calculated, in which a little more than 10 ha (2.5-3.0 t/ha) is required to obtain 25-30 tons of marketable products. With the bottom method, 4-6 sites of 1 ha (2.5-5.0 t/ha) will be needed for growing 10-30 tons. The latter value even exceeds the indicators of cage cultivation, although it has always been considered as more reliable and productive. In order to minimize or avoid some of the disadvantages of traditional breeding methods, a new method of growing scallops was applied at the mariculture site in Kozmina Bay: in an aviary. The essence of the method is that before the release of the yearlings, the site is fenced with a fence from Delhi, which protects the mollusks from many predators and prevents the scallops from moving outside the site.","PeriodicalId":498194,"journal":{"name":"Rybnoe hozâjstvo","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135829994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results obtained made it possible to develop the most optimal strategy for the fishery use of fish stocks, which is based on the maximum possible harvesting of the slow-growing population of bream, the irruption of which causes a further deterioration in feeding conditions for traditional commercial fish - carp and crucian carp. They are more in demand among the population and, accordingly, more profitable in the fishery, which is the first direction of the proposed strategy. The second direction of the strategy is the directed formation of the ichthyofauna with the predominance of the biomass of the most commercially valuable species - herbivorous fish, which is ensured by the existing significant reserves of phytoplanton and macrophytes. The introduction of herbivorous fish juvenile as objects of pasturable fish culture will increase fish productivity and produce annually from 20 to 55 tons of valuable fish products.","PeriodicalId":498194,"journal":{"name":"Rybnoe hozâjstvo","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135830006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the genetic diversity of the herd of the northern type Sarboyan carp was studied using the COX1 fragment of mitochondrial DNA, and phylogenetic relationships between modern breeds, subspecies and species of the genus Cyprinus were analyzed. The analyzed haplotypes of Sarboyan carp bred in the Moshkovsky district on the farm of ECO-PARK LLC revealed relatively low indicators of genetic polymorphism. Phylogenetic analysis conducted on the basis of its own haplotypes and haplotypes taken from the NCBI international database suggests that the Sarboyan carp is a deeply hybrid grouping, which confirms the known data on the origin of this breed. The study of the median haplotype network showed that the haplotypes of carp and wild carp form related haplogroups through one common haplotype. The Sarboyan carp is represented by three haplotypes, 75% of which belong to the star-shaped structure (H1), and the remaining 25% are represented by various breeds of carp and carp from both Eurasia and North America.","PeriodicalId":498194,"journal":{"name":"Rybnoe hozâjstvo","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135829993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unexplored areas in the technique and technology of baked fish and vegetable products using various types of equipment have been identified. In the process of research, the issues of combining lean fish species with products of plant origin, which mutually complement the amino acid composition of highly prepared semi-finished products, were considered. The main raw material for the production of cutlets was fresh frozen pink salmon fish with the addition of buckwheat, rolled oats, millet and rye flour, as well as powders of plant origin: freeze-dried dill, parsley and paprika, and onions, orange and yellow carrots, and milk were used as plant and animal raw materials, butter and chicken egg. For heat treatment, gentle heat treatment methods and modes were chosen: baking in a combi oven in the “steam” and “heat” modes and, for comparison, the same method – baking in an oven. Based on modeling the components of the recipe, taking into account their biological value, new taste qualities of baked fish cutlets were obtained. As a control, there were fish cutlets prepared according to the traditional recipe available in the regulatory documentation. The dependences of raw and heat-treated products and their influence on the structure of cutlets were revealed. The sensory characteristics of new semi-finished products with a high degree of readiness were obtained, taking into account processing in a combi oven and baking in an oven. The parameters of technological processes have been established for baking in the “steam” and “heat” mode at a temperature of 180-200 ° C in a combi oven, and at 200°C baking for 7 minutes, and then at a temperature of up to 250 ° C until the inside reaches 80°C (more 3-5 minutes). The dependences of milk, eggs and butter on the binding components of the formulation - herbal additives – have been identified. The resulting model formulation meets the requirements, regulatory documentation and consumer preferences. Baking in the “heat” mode is characterized by a loss of protein of 3,43-3,68%, fat – 0,02-0,23%, carbohydrates - 0,43-0,61%. Oven roasting has a gentler effect on nutrient loss. At the same time, the loss of protein is 2,00-2,49%, fat - 0,13-0,43%, carbohydrates – 0,11-0,46%.","PeriodicalId":498194,"journal":{"name":"Rybnoe hozâjstvo","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135829997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
