General waters of Central Kalimantan with an area of around 2.29 million Ha is a habitat for freshwater fish, both of which have important economic value and ecological value. Diversity of fish species is a potential for fisheries production both as consumption fish, fish traded between regions and ornamental fish. Based on the latest data, there are 267 species of fish in the public waters of Central Kalimantan and 92 species of which are included in the category of ornamental fish species (Central Kalimantan Marine and Fisheries Service, 2010). Batu Lake is located in Sigi Village, Kahayan Tengah District, Pulang Pisau Regency, Central Kalimantan Province. The area of the lake is approximately 12 km2, around the lake there are rafts and settlements, the distance from the capital city of Kahayan Tengah Subdistrict (bukit rawi + 3 km where the lake slightly enters, through a small road. The distance to the lake is about 250 m from the road) province, the condition of the lake is still natural and only used by residents of Tuwung as a place to find livelihoods (looking for fish and other river products) as well as a means of transportation to certain areas in foodplain waters such as the Lake Batu high water fluctuations (volume of water) in a year is very large. Ruaya fish means adjustment, confidence in conditions that benefit existence and for the reproduction of species with active and sometimes passive movements from one place to another. Effendi (1997) groups the family in the interests of spawning, ruaya to enlargement and food areas and refugee homes to avoid da ri place that is in a bad condition. This research is an effort to introduce the potential of freshwater natural resources in the Lake Batu District of Pulang Pisau in the form of ornamental fish. The inventory activity will provide information about potential types of ornamental fish with all the values of their superiority or attraction so that they can become superior commodities. This research was carried out in Batu Lake (2º 08'23.26 "S 113º 57.11'11.97" E) in Sigi Village, Kahayan Tengah District, Pulang Pisau Regency, Central Kalimantan Province. Collection is done by exploring primary and secondary data about the characteristics of biology, water quality. Water quality measurements are carried out directly in the location to obtain primary data, while secondary data is carried out through interviews with the community. The data obtained is then analyzed and explained in qualitative and quantitative descriptive so that it can provide representative information for the development of ornamental fish.

The present study has been conducted on ichthyofaunal diversity of river Kapaleswari flowing through Paschim Medinipur district of West Bengal, India. Results reveal the existence of 56 indigenous fish species under 22 families of 8 orders and the order Perciformes represents the largest diversity with 8 families and 20 species. Cyprinidae is the most dominant family; contributed 26.79% species. Two species namely Stigmatogobius sadanundio & Gobiopsis macrostoma have been first time recorded from Paschim Medinipur district of West Bengal. Among the recorded fish species of Kapaleswari River, 47.07% were used as food-fish, 1.79% used as ornamental & the remaining 57.14% were used as both food and ornamental. So, maximum fish species have important socio-economic value for the development of local people proximate to the Kapaleswari River. The values of the Shannon-Weaver index (H) range from ‘3.58’ to ‘3.79’ & the Simpson’s index (D) from ‘0.023’ to ‘0.032’ among the sampling sites are indicative to diverse fish population in Kapaleswari River. The result of species evenness has been concluded that individual species are near to disturb condition at Kapaleswari river. According to IUCN ver. 2020.1, status of the fishes in the river depicts, 75% are Least Concern, 3.57% are Vulnerable, 8.93% are Near Threatened, 10.71% are Not Evaluated & 1.71% are Data Deficient. As per local status 71.42% of fishes of this river are under risk and need immediate conservation to protect them from extinction. Hence, the work is a documentation of macro faunal diversity of Kapaleswari river as well as regional level for helpful for future researchers and policy planners and also helpful to formulate the future policy for conservation and management of the fish diversity in the river Kapaleswari.

Abstract Coastal zones are ecosystems of high economic value but exposed to numerous disturbances, while they represent nurseries for many fish species, raising the issue of the preservation of their functions and services. In this context, the juvenile fish assemblages of all types of habitats present in shallow coastal zones were studied on the south-east coast of France using underwater visual censuses. The abiotic and biotic descriptors of the 14 habitat types individualized did not vary with time, except for a higher cover percentage and canopy height of macrophytes in the warm period, which increased the three-dimensional structure of some habitats. The taxonomic composition and density of juvenile fish assemblages were analyzed using both multivariate and univariate descriptors, after grouping the 57 fish species recorded into 41 well-individualized taxa. Juvenile fishes were recorded in all habitat types, with higher mean species richness and abundance during the warm than the cold period. The richest habitats in terms of both species richness and abundance were the natural rocky substrates and the interfaces between Posidonia beds and the other habitats. Although juvenile fish assemblages differed among habitat types and between periods, the most abundant fish species (Atherina sp., Sarpa salpa, Gobiidae, Symphodus spp., Pagellus spp. and several Diplodus species) colonized different habitat types (from 7 to 14) during their juvenile life. This study provided evidence of the role of all types of shallow coastal habitats as fish nurseries and their varying pattern of occupation in space and time by the different juvenile stages. It highlighted the importance of the mosaic of habitats and interfaces for the complete development of all juvenile life stages of fishes, and for the preservation of a high diversity of coastal fish assemblages and fisheries resources in the Mediterranean Sea.

Cichlids include several fish species having a high economic value in the field of aquaculture. The ornamental fish export trade is mostly based on fish from the african Lake Malawi. Despite their huge economic importance, management of ornamental fisheries is challenged by a paucity of information on the status of the exploited fish stock. The possibility of guaranteeing healthy animals is of paramount importance and has several implications, both for commercial and sanitary reasons. Grossly, cutaneous nodules and black spots are pathological findings frequently encountered in fish, suggesting a meandering disease without a specific etiologic association. Ornamental fish species are plagued by mycobacteriosis, which is quite classically associated with granulomas. This work focuses on debilitated ornamental cichlids presenting cutaneous nodules and black spots and sampled during routinary managing activities held in an aquarium commercial facility; the fish underwent pathological analysis and the presence of pathogens was investigated through a molecular approach. In particular, the presence of lymphocystis disease virus (LCDV), typically associated with cutaneous nodular disease, was excluded.Histologically the granulomas were localized in the spleen, sometimes extending to the other visceral organs. Bacterial Heat-Shock Protein 65 PCR products were detected in tissues associated to granulomas and molecular investigation identified Mycobacterium spp. in two samples and Cutibacterium acnes in seven samples. Variably sized round “Hamazaki-Wesenberg-like” bodies were immunolabeled with C. acnes antibody within macrophages forming the granuloma in the spleen. C. acnes has been recently detected by Next Generation Sequencing in the microbiome of internal organs of fish. The role of C. acnes within internal fish tissues deserves attention; its role as potential granulomatogenous agent, is taken in consideration.

Cymodocea nodosa seagrass meadows provide several socio-economically ecosystem services, including nurseries for numerous species of commercial interest. These seagrasses are experiencing a worldwide decline, with global loss rates approaching 5% per year, mainly related to coastal human activities. Cymodocea nodosa, the predominant seagrass in the Canary Archipelago (Spain), is also exposed to these threats, which could lead to habitat loss or even local disappearance. In this case study, we estimated the potential economic value of Cymodocea nodosa seagrass meadows for local fisheries at an archipelago scale. Habitat suitability maps were constructed using MAXENT 3.4.1, a software for modelling species distributions by applying a maximum entropy machine-learning method, from a set of environmental variables and presence and background records extracted from historical cartographies. This model allows characterising and assessing the C. nodosa habitat suitability, overcoming the implicit complexity derived from seasonal changes in this species highly dynamic meadows and using it as a first step for the mapping and assessment of ecosystem services. In a second step, value transfer methodologies were used, along with published economic valuations of commercially-interesting fish species related to C. nodosa meadows. We estimate that the potential monetary value of these species can add up to more than 3 million euros per year for the entire Archipelago. The simplicity of the proposed methodology facilitates its repeatability in other similar regions, using freely available data and hence, being suitable for data-scarce scenarios.
