Abstract:

This paper brings some advances in fish data sampling and stream environments. Since the publication in 1999 of volume VI “Ecology of Stream Fishes” in the former Oecologia Brasiliensis journal, today Oecologia Australis, several progresses have occurred. Several methods of collecting fish themselves, have remained the same. However, in relation to the use of electric fishing, collection of eggs and fish larvae, and characterization of physical habitats in streams, there was remarkable development and improvement. The purpose of this article is to present the “state of the art” of these three

Abstract Semah fish (Tor tambroides, Bleeker 1854) is one of the asian endemic fish species that have high economic value. Living from this semah fish inhabits the upper reaches of the river, one of which is the upper reaches of the right upper Kampar river, which is located in Koto Kampar Hulu District, Kampar Regency, Riau Province. From the data and information obtained, the presence of the number of semah fish in the Kampar river continues to experience a decrease in population. The decline in the population of this semah fish is thought to be due to changes in the ecological conditions of

One of important habitat for estuarine fish and their juvenile are mangrove areas, as hundreds of studies had been conducted since 1950s until now to assess and understand the distribution and diversity of them over there. The study of population biology in tropical and sub-tropical mangrove estuaries nowadays have reached new level of achievement where they contribute significantly in the socio-economic field. So, the main objective of this paper are briefly described and reviewed some aspects of population biology (such as distribution and diversity) of mangrove fisheries in Malaysia. In the

The use of environmentally friendly fishing gear has been proven to have a positive impact not only on the aquatic ecosystem in the conservation areas of Agam Regency but also on the economic aspects of fishermen. The use of selective fishing gear can reduce over-exploitation of fish stocks, which ultimately creates a sustainable fisheries system. The aim of this study is to educate the use of bagan (fish trap) technology to improve the economy of fishermen in a better and more sustainable way.

Finding an alternative feed source for the replacement of fish oil (FO) and fish meal (FM) produced from whole fish has been an important issue for realizing sustainable aquaculture.

The quality parameter and nutrient components of FO and FM from UFB were analyzed. Although crude FO produced from UFB showed relatively poor quality properties, the refinement process made an improvement of the quality to make it comparable to commercially available FO.

Abstract:

The equator monument is one of the tourism icons of Pontianak City because the location of the tourist attraction is located at 0º of the imaginary line of the equator and is a sign of the boundary of the hemisphere North Latitude and South Latitude. The equator monument has a conservative nuance with environmental insight because the location of the object is associated with the longest river in Indonesia, the Kapuas River which is the lifeblood of the people of West Kalimantan from the social, economic, and cultural sectors. The purpose of this study was to conduct a conservative study of en

Thus, activities to be placed within this region should consider the compatibility between needs and the region’s ability in providing resources.

Abstract:

Livestock is an economic activity, dedicated to the breeding of animal species to take advantage of them and of its derivative products, as well as of livestock exploitation itself. However, when relating it to the sustainable use of natural resources in Northwest Mexico, there can be seen some situations that need to be addressed. The present study aims to analyze the production and conservation status of natural resources of beef cattle activity in the cow-calf system in Sonora, Mexico. The diagnosis was based on aspects of regionalization of livestock, the specific characteristics and issue

Hydropower remains a key renewable energy source in the pursuit of the decarbonization of the economy, although the relatively high potential impact of the hydro-morphological alterations it may cause poses significant concerns for aquatic ecosystems. In the last years, new technologies and practices have been increasingly adopted to minimize the impacts of hydropower plants, while improving efficiency and flexibility of energy generation. The overall effect of these innovations may be a more sustainable design and operation of hydropower, striking a better balance between the objectives of de

The practice of fishing with bombs not only damages marine habitats, including coral reefs, but also threatens the sustainability of fish resources in the future. If allowed to continue, this can harm marine ecosystems and jeopardize the sustainability of the local economy. To address this problem, training and implementing coral reef conservation using the

We addressed this gap in spatial detail by providing a review that compares and contrasts the exploitation history of China’s fisheries at both the national and provincial levels based on official statistical data.
