Juvenile fish

Juvenile fish go through various stages between birth and adulthood. They start as eggs which hatch into larvae. The larvae are not able to feed themselves, and carry a yolk-sac which provides their nutrition. Before the yolk-sac completely disappears, the tiny fish must become capable of feeding themselves. When they have developed to the point where they are capable of feeding themselves, the fish are called fry. When, in addition, they have developed scales and working fins, the transition to a juvenile fish is complete and it is called a fingerling. Fingerlings are typically about the size of fingers. The juvenile stage lasts until the fish is fully grown, sexually mature and interacting with other adult fish.

Growth stages

Ichthyoplankton (planktonic or drifting fish) are the eggs and larvae of fish. They are usually found in the sunlit zone of the water column, less than 200 metres deep, sometimes called the epipelagic or photic zone. Ichthyoplankton are planktonic, meaning they cannot swim effectively under their own power, but must drift with ocean currents. Fish eggs cannot swim at all, and are unambiguously planktonic. Early stage larvae swim poorly, but later stage larvae swim better and cease to be planktonic as they grow into juveniles. Fish larvae are part of the zooplankton that eat smaller plankton, while fish eggs carry their own food supply. Both eggs and larvae are themselves eaten by larger animals.

Fish anatomy

Fish anatomy is the study of the form or morphology of fishes. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish. In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in the living fish.

The anatomy of fish is often shaped by the physical characteristics of water, the medium in which fish live. Water is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs more light than air does. The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish, is either made of cartilage, in cartilaginous fish, or bone in bony fish. The main skeletal element is the vertebral column, composed of articulating vertebrae which are lightweight yet strong. The ribs attach to the spine and there are no limbs or limb girdles. The main external features of the fish, the fins, are composed of either bony or soft spines called rays, which with the exception of the caudal fins, have no direct connection with the spine. They are supported by the muscles which compose the main part of the trunk. The heart has two chambers and pumps the blood through the respiratory surfaces of the gills and on round the body in a single circulatory loop. The eyes are adapted for seeing underwater and have only local vision. There is an inner ear but no external or middle ear. Low frequency vibrations are detected by the lateral line system of sense organs that run along the length of the sides of fish, and these respond to nearby movements and to changes in water pressure.

Fish (UK TV series)

Fish is a British television drama series first broadcast on BBC One in 2000. It features Paul McGann as the title character, alongside Jemma Redgrave and Mick Ford. It was created by Stephen Tredre, written by Tredre and Matthew Bardsley, and co-produced by the BBC and Principle Pictures.

Premise

Jonathan "Fish" Vishnevski (McGann) is an employment lawyer who specialises in industrial tribunals. His wife has left him and gone abroad, leaving him to look after their young son, Simon (Jack Stanley). In court, he often comes up against lawyer Joanna Morgan (Redgrave), who becomes his love interest. His friend Trevor (Ford) is an amateur philosopher who owns a mobile burger bar.

Additional characters include Ivan Vishnevski (Philip Voss), Harold Cornice (Stephen Moore), Sarah Cornice (Jill Baker) and Jess Taylor (Daniela Denby-Ashe).

Creation and production

The series was inspired by the brother of producer Miriam Segal and conceived by Stephen Tredre in 1994, who took up screenwriting due to illness. After obtaining funding from Principle Pictures, Segal approached ITV and then the BBC with the programme, who both turned it down. It was then offered to the BBC's regional drama department, BBC Birmingham, and the series was commissioned. After reorganisation within the BBC, the series was announced in 1999 by the corporation's drama head, Mal Young.

Fish (Craig Campbell song)

"Fish" is a song co-written and recorded by American country music singer Craig Campbell. It was released in June 2011 as the second single from his self-titled debut album. Campbell wrote this song with Arlos Smith and Ashe Underwood.

Content

The song's rhyming scheme implies the word "fuck", which is replaced at the last second by "fish" ("I had everything we needed in the back of my truck / Turns out my baby loves to fish").

Critical reception

William Ruhlmann of Allmusic described the song as "a single-entendre joke of the kind that hasn't been heard since that old sophomoric tune 'Shaving Cream'".

Matt Bjorke of Roughstock gave the single three stars out of five, saying that it "may not be deep or anything of that sort but it is perfect for summer time playlists and that ultimately makes it a successful single."

Music video

The music video was directed by Wes Edwards and stars the host of the World Fishing Network's Hookin' Up with Mariko Izumi, who plays his love interest.

309 Road

The 309 road is a 22-kilometre (14 mi) long gravel road between the towns of Coromandel and Whitianga in New Zealand.

The 309 winds its way from Coromandel, on the west side of the Coromandel Peninsula, over the ranges to Whitianga, on the eastern side.

The road is considered extremely dangerous and deaths among tourists unfamiliar with the road and in unfit vehicles are common.

Places of interest along the road include Waiau Falls and the Kauri Grove, a stand of mature kauri trees.

2+2 road

A 2+2 road is a specific type of dual-carriageway being built in Ireland and in Sweden and in Finland, consisting of two lanes in each direction separated by a steel cable barrier.

These roads do not have hard shoulders and therefore they cannot be designated as Motorway at some future date. The Irish variant,however, has 3.5m lanes where there are a number of Swedish variants some with 3.25m wide lanes.

Junctions are generally at-grade roundabouts and minor roads cross under or over the mainline without connecting. They are also known as "Type 2 dual-carriageways" by the Irish National Roads Authority. These roads look similar to expressways, except that expressways often have interchanges, large medians or concrete barriers between traffic. The United States has 80,000 km of roads that fit this description.

First 2+2

The first road of this type opened in December 2007 as a new greenfield section of the N4 national primary route which joins Dublin to Sligo.
