Genetic Resources for Aquaculture: Status and Trends
109 Genetic resources for aquaculture: status and trends Roger S.V. Pullin 7A Legaspi Park View, 134 Legaspi Street, Consultant, Philippines 1. SUMMARY Aquaculture, the farming of aquatic plants and animals, has grown consistently since 1970, when it provided only 3.9 percent of world fish supply. In 2004, global production of farmed fish (mainly crustaceans, molluscs and finfish) was over 45 million tonnes, comprising about 32 percent of total world fish supply, while the total production of farmed seaweeds for food and extraction of chemicals, was about 13.9 million t. Aquaculture also provides increasing proportions of the world’s supply of ornamental aquatic organisms. Over 90 percent of aquaculture takes place in developing countries, where it has high importance for poor people in terms of nutrition and livelihoods and where further responsible development of aquaculture, integrated with other natural resource use, has high potential for future growth. Based upon statistics submitted to FAO by its member States, about 84 percent of farmed fish production comes from Asia, with 67 percent coming from the Peoples’ Republic of China. However, aquaculture is increasing in importance in all developing regions and is expected to provide about 50 percent of world food fish supply within the next 20 years. The future of aquaculture will depend in large measure upon the effective management of the genetic resources for farmed aquatic plants (PGR) and farmed fish (FiGR), as well as those for the organisms that provide their food and ecosystem services. Fish farms are agroecosystems and aquatic genetic resources for aquaculture on farms are part of agrobiodiversity. -

IUCN Otter Spec. Group Bull. 38(2) 2021 N O T E F R O M T H E E D I T O R NOTE FROM THE EDITOR Dear Friends, Colleagues and Otter Enthusiasts! I can only hope that you all are safe and healthy. I understood that some are already vaccinated. For the rest I hope we all manage to stay safe and healthy until it is our turn. This year we are now much faster than in previous years to get manuscripts online. We are hard working with Lesley to remove all the backlog to the point when we will be able to upload each manuscript on the date the proofprint has been accepted by the authors. You may be well aware that the IUCN OSG Bulletin, via me, became a member of the Committee on Publication Ethics (COPE) some years ago. As part of this, I sometimes use anti-plagiarism software to check manuscripts before sending them out for review. Another aspect is that authors submitting manuscripts should carefully consider the list of authors as there are strict rules on how to add an additional author after the original submission, which creates a lot of work for me and them. I want to use the opportunity to ask all authors to carefully double check their reference, and the list of references. It is so much work for Lesley to sort this out and then, especially, find the missing references. Many thanks to Lesley for all endless hours and hours spent not only for getting manuscripts online but also doing the extra work to double-check the manuscripts for typos and the one always missing reference. -

Ecology, diversity and seasonal distribution of wild mushrooms in a Nigerian tropical forest reserve. Biodiversitas 19: 279-284. Aquatic plants play a crucial role in an aquatic ecosystem partly because these plant communities provide suitable habitats and food items to other aquatic organisms especially fish. Many fish communities use vegetation as breeding sites, nurseries and refuges for their juveniles. Therefore, this study was conducted to provide baseline data on the correlation between the aquatic plants and freshwater fishes in Perak River. Based on the findings, the abundance of aquatic plant influences the growth and health of the fish. Habitats with moderate amounts of aquatic vegetation provide the optimal environment for many fish and hence, increase the fish diversity, feeding, growth, and reproduction. In contrast, both limited and excessive vegetation may decrease fish growth rates at 75% to 85% of plant community coverage. The recent trip along the Perak discloses the presence of these aquatic plants at certain habitats. There is a positive correlation between aquatic plants and freshwater fish. The association between aquatic plants and fish assemblages has been documented in scientific studies with the conclusion that moderate plant densities could enhance the fish diversity, feeding, growth, and reproduction. -

Biodiversitas 22: 2131-2135. Research on feeding habits of Tinfoil barb, Barbonymus schwanenfeldii was carried out in the Tasik River from July to August 2020. This study aims to determine the composition of foods consumed by Tinfoil barb fish, and the availability of natural food in the Tasik River from 3 sampling stations. Fishes were caught using a gillnet with a mesh size of 3.18 cm, then the fish samples were dissected, and the digestive tract was taken and preserved with 10% formalin. A total of 138 Tinfoil bars were caught for this study. Analysis of stomach contents found that Tinfoil barb ate phytoplankton (41-48%) as the primary food, moss (25-38%), plant pieces (13-17%), worms (2-11%) as a complementary food and few of insects (0-4%), zooplankton (0-1%) as other foods. -

The spotted snakehead, Channa punctatus is a highly priced freshwater food fish species in India. The culture of snakeheads is still not common due to the scarcity of quality seed supply and lack of knowledge on their feeding and breeding techniques. Therefore an experiment was conducted to test the efficacy of a new spawning agent, Ovatide in stimulating ovulation of snakehead fish under a controlled captive condition. Materials and Methods. In total, 12 matured females and 24 male fish weighing 50–90 g were randomly select - ed for three hormonal treatment groups and one control group. Both male and female fish in each treatment group were administered with either saline (0.9% NaCl, control group), or 0.2, 0.4, and 0.6 mL of Ovatide per kg of body weight (BW), respectively. Each breeding set consisted of two males and one female. -

Traditional morphometric characters were measured in 150 fish samples Introduction (50 individuals of every taxon). The results of univariate (ANOVA) and multivariate (Discriminant function analysis, Barbonymus belongs to the Cyprinidae family, and DFA) analyses showed that lampam-A and lampam-B have overlapping morphological characteristics, whereas naleh this species is a true freshwater fish that is omnivo- were distinctly different.
