The evolution of this amount is very sensitive to human diets and to the productivity of feed. -
State-Of-The-Art on Use of Insects As Animal Feed
State-of-the-art on use of insects as animal feed Harinder P.S. Makkar1, Gilles Tran2, Valérie Heuzé2 and Philippe Ankers1 1 Animal Production and Health Division, FAO, Rome 2 Association Française de Zootechnie, Paris, France Full reference of the paper: Animal Feed Science and Technology, Volume 197, November 2014, pages 1-33 Link: http://www.animalfeedscience.com/article/S0377-8401(14)00232-6/abstract http://dx.doi.org/10.1016/j.anifeedsci.2014.07.008 Abstract A 60-70% increase in consumption of animal products is expected by 2050. This increase in the consumption will demand enormous resources, the feed being the most challenging because of the limited availability of natural resources, ongoing climatic changes and food-feed-fuel competition. The costs of conventional feed resources such as soymeal and fishmeal are very high and moreover their availability in the future will be limited. Insect rearing could be a part of the solutions. Although some studies have been conducted on evaluation of insects, insect larvae or insect meals as an ingredient in the diets of some animal species, this field is in infancy. Here we collate, synthesize and discuss the available information on five major insect species studied with respect to evaluation of their products as animal feed. The nutritional quality of black soldier fly larvae, the house fly maggots, mealworm, locusts- grasshoppers-crickets, and silkworm meal and their use as a replacement of soymeal and fishmeal in the diets of poultry, pigs, fish species and ruminants are discussed. The crude protein contents of these alternate resources are high: 42 to 63% and so are the lipid contents (up to 36% oil), which could possibly be extracted and used for various applications including biodiesel production. -

Morphological variation of two common sea grapes (Caulerpa lentillifera and Caulerpa racemosa) from selected regions in the Philippines. Biodiversitas 21: 1823-1832. Seagrapes, locally known in the Philippines as “lato” or “ar-arusip”, are economically important macroalgae belonging to the edible species of the genus Caulerpa. This study characterized and compared distinct populations of sea grapes from selected regions in the Philippines and described the influence of physicochemical parameters of seawater on their morphology. Morphometric, cluster and principal component analyses showed that morphological plasticity exists in sea grapes species (Caulerpa lentillifera and Caulerpa racemosa) found in different sites in the Philippines. These are evident in morphometric parameters namely, assimilator height, space between assimilators, ramulus diameter and number of rhizoids on stolon wherein significant differences were found. This evident morphological plasticity was analyzed in relation to physicochemical parameters of the seawater. Assimilator height of C. racemosa is significantly associated and highly influenced by water depth, salinity, temperature and dissolved oxygen whereas for C. lentillifera depth and salinity are the significant influencing factors. -

The students and instructors (Drs. Brian Wysor, Roger Williams University; Wilson Freshwater, University of North Carolina at Wilmington; Suzanne Fredericq, University of Louisiana at Lafayette) worked synergistically with the Smithsonian Institution's DNA Barcode initiative. As part of the Bocas Research Station's Training in Tropical Taxonomy program, lecture material included discussions of the current taxonomy of marine macroalgae; an overview and recent assessment of the diagnostic vegetative and reproductive morphological characters that differentiate orders, families, genera and species; and applications of molecular tools to pertinent questions in systematics. Instructors and students collected multiple samples of over 200 algal species by SCUBA diving, snorkeling and intertidal surveys. As part of the training in tropical taxonomy, many of these samples were used by the students to create a guide to the common seaweeds of the Bocas del Toro region. Herbarium specimens will be contributed to the Bocas station's reference collection and the University of Panama Herbarium. -
Economics of Aquaculture Feeding Practices in Selected Asian Countries Economics of Aquaculture Feeding Practices in Selected Asian Countries
ISSN 0429-9345 505 FAO FISHERIES TECHNICAL PAPER 505 Economics of aquaculture feeding practices in selected Asian countries Economics of aquaculture feeding practices in selected Asian countries This technical paper provides an analysis of the economic implications of, and the reasons for, adopting various feeding practices for different fish species and aquaculture systems in Asia. It consists of case studies in six Asian countries (Bangladesh, China, India, the Philippines, Thailand and Viet Nam) and an overall synthesis ending with conclusions and recommendations. The systems studied include extensive/traditional, semi-intensive and intensive farms for a number of different species including sutchi and pangasiid catfishes (Bangladesh and Viet Nam), hybrid catfish (Thailand), carp polyculture (India and China), prawn and milkfish polyculture (the Philippines). The work identifies the principal input costs, assesses the economic rates of return (gross and net margins), returns to labour, land and capital, gross and net total factor productivity, and break-even prices and production. For the most part, intensive farms applying industrial feeds attained the highest economic returns, although not necessarily the highest benefits. In many cases, feed costs were extremely high, accounting for over 80 percent of the total. Feed cost, feeding rate, stocking rate, recovery or survival rate and fertilizer cost were identified as the key variables in influencing production. Use of intensive farming was consistent with strong farmer education and good extension practices. It is expected that the results of these studies will assist in adopting appropriate feed management strategies depending on the availability of inputs and the level of technical know-how of the farmers. -

Salinity, temperature, nutrients, and light are considered essential parameters to explain growth and dis- tribution of macroalgal assemblages in coastal zones. Goals. In order to evaluate the effect of salinity on the growth properties of Caulerpa sertularioides, we conducted this study under laboratory conditions to find out how salinity affects the distribution of this species in coastal tropical environments. Methods. Five ranges of salinity were used for the experi- ments (15, 20, 25, 30, and 35 ppt), simulating in situ salinity conditions on the south Pacific Coast of Colombia. The culture was grown in an environmental chamber with controlled temperature and illumination, and a 12:12 photoperiod. The following growth variables were measured weekly: wet biomass, stolon length (cm), number of new fronds and rhizomes. In the experimental cultures, growth (increase in wet biomass and stolon length) was calculated as the relative growth rate (RGR), expressed as a percentage of daily growth. -
Algae Sheets-Invasive Elsewhere
ALGAE: NATIVE, INVASIVE ELSEWHERE Caulerpa taxifolia (Vahl) C. Agardh 1822 Caulerpa taxifolia has gained worldwide attention and the nickname killer algae because of its great success in coastal Mediterranean waters. It is a native species in Hawaii where it has not exhibited invasive tendencies. Division: Chlorophyta Class: Ulvophyceae Order: Bryopsidales Family: Caulerpaceae Genus: Caulerpa PHOTO: A. MEINESZ IDENTIFYING FEATURES HABITAT DESCRIPTION In Hawaii, small patches grow in sandy areas of tidepools and reef flats. In its maximum invasive Branches, feather-like, flattened, and upright, 3 - 10 cm state, it can cover all favorable available substrates, high, rising from a creeping stolon (runner), 1 - 2 mm including rock, sand, and mud. in diameter, anchored by rhizoids to the substrate. Branchlets oppositely attached to midrib, flattened, slightly curved upwards, tapered at both base and tip, and constricted at point of attachment. Midrib is slightly flattened, appearing oval in cross-section. This species resembles another Hawaiian Caulerpa species, C. sertularioides. C. sertularioides is more delicate and the branchlets are rounded, compared to the flattened branchlets of C. taxifolia. The rising branches are also more rounded toward apices, compared to the more angular, squared-off branches of C. taxifolia. COLOR PHOTO: A. MEINESZ Mediterranean Sea Dark green to light green.

Goldberg Johns Hopkins University KEYWORDS farm animal welfare, CAFOs, sustainable intensification, human health, aquaculture ABSTRACT The paper examines the relationship between farm animal welfare, industrial farm animal production, and human health consequences. The data suggest that when the animal welfare of land-based farm animals is compromised, there are resulting significant negative human health consequences due to environmental degradation, the use of non-therapeutic levels of antibiotics for growth promotion, and the consequences of intensification. This paper accepts that even if meat and fish consumption is reduced, meat and fish will be part of the diet of the future. Industrial production modified from the current intensified systems will still be required to feed the world in 2050 and beyond. This paper identifies the concept of sustainable intensification and suggests that if farm animal welfare is improved, many of the human health consequences of intensified industrial production can be eliminated or reduced.
