#Vegetarian diet for fish: Scientists discover key to easing aquacultures reliance on wild-caught fishfor the first time scientists have been able to develop a completely vegetarian diet that works for marine fish raised in aquaculture the key to making aquaculture a sustainable industry as the world's need for protein increases.
and Aquaculture the team has proven that a completely plant-based food combination can support fast-growing marine carnivores like cobia
and gilthead sea bream in reaching maturity just as well as--and sometimes better than--conventional diets of fish meal and fish oil made from wild-caught fish.
Nearly half of the world's fish and shellfish supply is supplied by aquaculture--growing fish in tanks
or ponds instead of catching them from the oceans or streams--and scientists have been trying to figure out how to make growing fish sustainable.
Many high-value fish such as cobia sea bream and striped bass are predators and eat other fish to survive
and grow. As a result their food in captivity is made of a combination of fishmeal
and fish oil and must be caught from the wild to feed them. This is expensive (for example it can take 5 pounds of wild fish to produce one pound of fish)
and it further depletes the world's fisheries. This makes aquaculture completely sustainable said Dr. Allen Place.
The pressure on natural fisheries in terms of food fish can be relieved. We can now sustain a good protein source without harvesting fish to feed fish.
The replacement of fishmeal and fish oil in aquaculture diets has been a goal for researchers for decades
but has met with limited success. The team's research centered on evaluating fishmeal-free plant protein-based diets originally developed for rainbow trout by the USDA-Agricultural research service
and modifying them to replace the fish oil for cobia and potentially other high-value high-value marine carnivores.
and muscle growth and is found in high levels in carnivorous fish and their prey.
and ease the pressure on catching wild fish raising fish on a vegetarian diet also means cleaner fish to eat with levels of PCBS and mercury as much as 100-fold lower.
Right now you are supposed only to eat striped bass once every two weeks said Place. You can eat aquaculture-raised fish twice a week
because levels are so low. The study Taurine Supplementation of Plant Derived Protein and n-3 Fatty acids are Critical for Optimal Growth

#Color patterns in fish larvae may reveal relationships among speciessimilarities in how different organisms look can indicate a close evolutionary relationship.
Conversely great differences in appearance can suggest a very distant relationship as in many adult marine fish species.
For the first time however a Smithsonian scientist has found that color patterns of different fish species in the larval stage can be very similar revealing a closer evolutionary relationship than their adult forms would suggest.
Many marine fish species spend their larval stage near the ocean's surface#n environment completely different than the one they are in as adults.
and appearances resulting in fish in their larval stage that bear little to no resemblance to their adult counterparts.
Carole Baldwin a zoologist at the Smithsonian's National Museum of Natural history examined more than 200 species of marine fishes in their larval stage primarily from the western Caribbean.
Biologists artists and tropical fish aquarists have described illustrated or photographed color patterns in adult marine fishes for centuries
but color patterns in marine fish larvae have largely been neglected said Baldwin. Yet the larval stages of many marine fishes have subtle to striking ephemeral color patterns that can potentially tell us a lot about a species'place on the taxonomic family tree.
Adult mullets for instance are very different in appearance than adult flying fish yet when Baldwin examined these fishes in the larval stage she noticed that they share a unique transformation of color pattern that supports the idea that they could be related closely.
Larvae of some species in the order Tetraodontiforme like the pufferfish and those in the order Lophiiforme like the anglerfish are strikingly similar in having the trunks of their bodies enclosed in an inflated yellow sac.
Their appearance as adults however would not hint at a close relationship. More investigation of larval color patterns in marine fish is needed to fully assess their value in phylogenic reconstruction said Baldwin.
But the evidence I've found so far is promising that this will be an important taxonomic resource in the future.
Color information on many more marine fish larvae is needed to fully use this new suite of evolutionary information
and Baldwin will encourage colleagues to obtain color photographs of larvae when possible. And studies on the formation of pigment such as those conducted on the model freshwater zebrafish (Danio species) are needed.

#Flipping fish adapt to land livingresearchers have found that the amphibious mangrove rivulus performs higher force jumps on land than some other fishes that end up on land.
This new study shows that unlike the largemouth bass which makes very few excursions on land the mangrove rivulus
A team of researchers headed by Benjamin Perlman at Wake Forest University in the United states filmed juvenile largemouth bass
and amphibious mangrove rivulus jumping off a force plate when startled with the end of a stick
The largemouth bass uses a common jumping technique to return to the water when stranded on land a c-jump
The mangrove rivulus on the other hand does a tail flip whereby it flips its head over its body towards the tail end to jump away from a stimulus. The researchers found striking differences in these fish's jumping forces:
the bass generates forces mostly in the vertical direction which means that it basically just goes up without moving sideways;
the mangrove rivulus generates the greatest forces in the antero-posterior (front-back) and medio-lateral (side-to-side) dimensions
which allows it to effectively move in a particular direction. Benjamin Perlman said: Bass are very poor performers at jumping on land as expected
The amphibious rivulus is adapted better to land living and capable of directing its jumps on land using more forceful jumps.
Mangrove rivulus which can live out of the water for extended periods of time (days or weeks as long as the conditions are moist) uses its specialised jumping technique
Bass are stranded only temporarily on land when chased out of the water by a predator caught in a current and washed onto land

and low-oxygen conditions that endanger fish and other aquatic life. At Tanguro Ranch however the soils are old
Warmer water has implications for the fish Neill says because it holds less oxygen. Warmer water also increases fish metabolism
so fish need more food. We don't know if warming and other changes associated with expanding cropland also increase fish food supply

Largest and most comprehensive studies of fish phylogenyfishes account for over half of vertebrate species but while groups such as mammals birds and reptiles have been understood fairly well by scientists for decades knowledge about relationships among many types of fishes was essentially unknown--until now.
A team of scientists led by Richard Broughton associate professor of biology at the University of Oklahoma published two studies that dramatically increase understanding of fish evolution and their relationships.
They integrated extensive genetic and physical information about specimens to create a new tree of life for fishes.
The vast amount of data generated through large-scale DNA sequencing required supercomputing resources for analysis. The result is the largest and most comprehensive studies of fish phylogeny to date.
Broughton notes The scope of the project was huge in terms of the number of species examined
and the number of genes analyzed and the new patterns of relationships among fish families result in
what may be the broadest revision of fish systematics in history. While some of the findings provide new support for previously understood fish relationships others significantly change existing ideas.
Many different groupings are proposed in this new tree. For example tunas and marlins are both fast-swimming marine fishes with large streamlined bodies yet they appear on very different branches of the tree.
Tunas appear to be more closely related to the small sedentary seahorses whereas marlins are close relatives of flatfishes
which are bottom-dwelling and have distinctive asymmetric heads. Beyond a better understanding of fishes themselves the potential implications of this research are said wide reaching Edward Wiley curator of ichthyology at the University of Kansas. Our knowledge about one group can be extended to closely related species
if we understand those relationships Wiley said. He noted that knowledge of evolutionary relationships among fishes improves scientists'ability to predict how closely related species might react to environmental factors such as climate change.
It helps identify and target potential biomedically beneficial substances and has broader applications related to exploring disease-causing genes
and developmental processes shared with humans. The fish tree is the result of years of work among a collaborative team of scientists as part of the National Science Foundation-funded Euteleost Tree of Life project.
Researchers involved in the project include Broughton Wiley and Guillermo Ortã George washington University; Kent Carpenter Old Dominion University;
and a dog tracking team working with the California Department of Fish and Wildlife have captured 37 lions to date.

Before Robertson said co-author John Marlin Phd a research affiliate at the University of Illinois's Prairie Research Institute who had recollected part of Robertson's network in the 1970s almost all insect collecting was done independently of the plant.
That person turned out to be Marlin. All through high school I studied bees and ants he said
One of the plants Marlin studied was Claytonia virginica commonly known as'spring beauty.''We were interested very in Claytonia virginica
Marlin's dataset gave us visitation rate a quantitative measure of pollination we otherwise wouldn't have had.
Comparing the visitation rates we measured to Marlin's we discovered that the bees were making fewer trips to the flowers than they had in the 1970s.
Marlin counted 0. 59 bee arrivals per minute and we counted 0. 14 arrivals. So even those some interactions are still present they're weaker.
Both Robertson and Marlin had collected their bees pinned them and deposited them in the Illinois Natural history Survey often still fuzzy with pollen.
and Knight picked six bee species that frequently visited Claytonia virginica two named by Robertson and washed Robertson's archival specimens of those bees Marlin's specimens and their own.
The fraction of the pollen on the bee contributed by Claytonia virginica was highest in Robertson's time lower in Marlin's time and much lower in 2010.
