Ovarian transparent thin line; the naked eye can not distinguish between male and female, do not see the eggs, no surface blood vessels or even thin. for Not reached sexual maturity younger individuals possess. Phase II. Ovarian more Chengbian strip, there are many blood vessels in the ovary, and testis has been able to distinguish, but the naked eye can not see yet Clear eggs, which have not yet been deposited eggs yolk. Phase III. ovarian volume increase due to the growth of eggs, ovarian vascular development, the naked eye can see the accumulation of yolk eggs, But eggs are not big enough to round and can not be separated from the ovary peeled fold. Stage IV. ovarian eggs filled with yolk, ovarian membrane is very thin, the surface of the blood vessel is developed, the eggs from the ovary easily fold Wrinkle on falling down, sometimes squeezing the abdomen may have a small amount of eggs. Stage V. the spawning period, the ovary has been fully mature, was soft-like, eggs from the ovary fold off, discharged into the ovary chamber (Or abdominal), the lifting or broodstock Gently press the abdomen that is mature eggs in the outflow from the cloaca. VI of. producing eggs will survive beyond the ovary, a number of spawning fish, ovarian atrophy was deflated bladder surface vascular congestion, after Into Phase II; batch spawning fish, there are still developing ovarian oocytes third and fourth phase, and after a period of time Development of production and then the next batch of eggs. Therefore, such short-term recovery after ovary by VI of the transition to stage IV. b) testis staging Phase I. I ovarian characteristics and the same is not reached sexual maturity younger individuals possess. Phase II. linearly or thin ribbon glands, translucent or opaque surface of the vessel was not significant. Phase III. a circular rod-shaped, extruded fish belly cut testis or no semen, when making testis section collapse; not Small fish Ⅲ of testis was red meat. Stage IV. The milky white, surface blood vessels significantly, as testis section, section collapse; squeeze the belly with white semen flow The semen into the water immediately after the dissolution scattered, this time has matured. Stage V. reproductive period, testis soft, filled with milky semen, lift the head or abdomen that is light pressure from a lot of semen Gonopore outflow. VI period. reproductive testis after, smaller in size, appearance wilt deflated, after recovery into Phase III. 3.12 Gonad weight gonad weight The total mass of the gonads, in grams (g). 3.13 Mature coefficient coefficient of maturity or gonadosomatic index (GSI) Gonad weight refers to the percentage of body weight (generally refers gutted weight), showing the relative size of the gonad index, used to measure Gonadal development degree and body distribution ratio between the energy resources and somatic gonad. 3.14 Sex ratio sex ratio Referring to the same survey the number of individuals of different sex ratio waters of the same species. 3.15 Survival survival rate Start time refers to the ratio of the number of individual fish stocks at a certain period and termination. 3.16 Stuffed fish intestine degree intestine fullness It indicates how much food in the fish intestine, divided into grade 6. 0. empty intestine; Level 1.

4 observations principle

4.1 Scientific Principles Observation plots and observing the object should be representative, can fully reflect the overall situation of the observation area fish species resources; should Unified and standardized methods of observation, can observe the dynamic changes of fish species resources. 4.2 operability principles Observing programs should be considered owned by the human, financial and logistical support and other conditions, make full use of existing data and results, Li Foot existing observation equipment and personnel conditions should be high efficiency, low cost methods of observation. 4.3 principles of sustainability, Observations should meet the needs of fish species resources conservation and management, and is able to play in biodiversity conservation and management means Pilot and early warning. Observing objects, methods, time and frequency, once established, should remain fairly constant. 4.4 Principle of protection Maximize the use of non-invasive sampling method, to avoid frequent observation unscientific. To capture the key protected wild aquatic animals Sampling or logo, it must obtain administrative permission of relevant authorities. 4.5 Security Principles Biodiversity Observation fish has certain characteristics of field work, the observer should receive professional training, the observation process should Good security measures. 4.6 Applicability of the principle of According to the observed water body shape, size, flow and other environmental conditions, select the appropriate methods of observation. Produced fish with pelagic eggs Early resources survey methods, survey methods catch, hydroacoustic sonar survey methods and mark-recapture method can be used in large lakes, River fish observation. Fish independent sampling methods, early resource survey methods yield Shen viscous fish eggs can be used for small shallow lakes, Small rivers, caves and mountain streams of fish observation.

5 Methods of Observation

5.1 Observations ready 5.1.1 determine observation target Observations can grasp the target observation area fish species diversity, community and population structure, early supplementary resources, geographic points Cloth, or to analyze the impact of human activities and environmental changes on fish species resources, or for the manufacture of fish species resources protection measures Provide basic data set, as well as evaluate the effectiveness of fish protection measures and policies. 5.1.2 clear observation target According to the observation target, it should have a general observation to select objects of different ecological needs and life history of the taxa. In consideration thereof Species diversity of observation should also focus on the following groups of observations. a) threatened species, protected species and endemic species; b) has an important social and economic values of the species; c) the maintenance of ecosystem structure and process of the system has an important role in species; d) on the environment or climate change sensitive indicator species. 5.1.3 develop observation program Collection of observational regional natural and socio-economic conditions of the information, learn ecology and population characteristics of the observed object, if necessary We can carry out a pilot study for the development of the observation program ready. Observations plan should include. observation content, elements and indicators, 4 observation time and frequency, sample size and sampling methods, methods of observation, data analysis and reporting, quality control and safety management. 5.1.4 Staff training Good training methods of observation, field practices and other aspects, to ensure that the viewer can master all kinds of instruments As well as collection and identification method using fish specimens. At the same time, do a good job safety training to enhance safety awareness, emphasize field sampling It should pay attention to matters, to prevent dangerous incidents. 5.1.5 measurement and control equipment Ready instruments and equipment required for the observation of fish resources (see Appendix A). Check and debug related equipment, indeed Security equipment in good condition for long-term placement of the instrument accuracy correction. 5.2 observation point setting section or the like 5.2.1 lakes, reservoirs and other open waters According to the water sediment, composed of aquatic plants, water depth, water, lakes and reservoirs shape, water quality and other factors divided into several cells, So that the degree of variation within the same cell as small as possible. Within each cell, there are provided a plurality of representative samples. The number of samples can be According to the cell body of the lake area, form factor and habitat characteristics, working conditions, observation purposes, and so funding is determined. General situation Under conditions, the lake water is greater than 2 km2 body when no less than three samples. For Tongjiang lakes, make sure the main tributaries into the lake, the main lake Area and through the river channel must set the sampling point. The main tributaries into the lake sampling number not less than two. For through the river channel, sample Not less than two points, away from entrances and Tongjiangkou some distance set samples, respectively. 5.2.2 rivers or river reservoir According river morphology, river sediment, water, water, water quality and other factors, the river is divided into several sections, so that the same Section on the degree of variation as small as possible. Set a certain distance on the same sample every section. 5.3 Early fish resources survey 5.3.1 Early production of fish with pelagic eggs resources survey The method is applicable to a river or lake into the lake, the lake water flow passage. 5.3.1.1 Quantitative collection point. Accordance with the provisions of HJ 628. Sample point selection relatively flat in the bank, the water smooth, The flow rate was 0.3 ~ 1.0 m/s, fluid stable location, away from the banks of 20 ~ 100 m. Sampling point is set near a mainstream side. The jiang mesh (mesh 0.50 ~ 0.80 mm) or conical net (mesh 0.50 ~ 0.80 mm) fixed near the ship or Fulcrum shore, collecting twice a day, the acquisition time is 6.00 - 7.00 and 18.00 - 19.00, each acquisition of about 1 h. collection Time can be adjusted according to the actual situation. Sampling process is as follows. a) The acquisition nets suspended from the winch cable; b) start windlass, release cable, the network will be collected into the water; c) network port at the beginning of the aqueous layer reaches a predetermined timing and recording; d) to observe the cable counter and inclinometers degree; e) The flow meter is installed in the central network port, Ethernet port flow rate measurement; f) an acquisition until a predetermined period of time, open winches, pull collection nets, while lifting record when collecting network between; g) sorting eggs, larvae, juveniles, etc; h) during the sampling period, the flow rate measurement, transparency, water temperature, pH, dissolved oxygen and other environmental factors. 5.3.1.3 Qualitative acquisition. Accordance with the provisions of HJ 628. In eggs, larvae "fat river" is qualitatively adopt jiang network set. Eggs obtained larvae mainly for the culture observation. Qualitative usually collected continuously day and night, continued 24 h, when offline Interval between 2 ~ 4 h, each collecting 15 ~ 30 min, such as when the case of rain impurities, according to the actual situation, appropriate to shorten sampling time. After the acquisition is completed, the eggs, larvae and other impurities brought together in the laboratory sorting, culling form Intact, normal behavior of eggs, larvae were cultured and observed until it can accurately identify species. Section 5.3.1.4 collection. Using cone nets, were collected in the quantitative section on which point, the collection point for the left bank of the nearshore, left 1/2 shore to the river in the distance, the river, the right bank of the river to 1/2, right bank nearshore, a total of five points, from the left side of the riverbank To the other side five points are numbered A, B, C, D, E. At depths greater than 3 m of sample points, each collection point collection table, The bottom three samples, numbered 1, 2, respectively, for the depth of the corresponding collection points 0.2,0.5,0.8 times water depth (Fig. 1); at a depth greater than 1 m, less than 3 m of samples, conduct surface and bottom samples; at a depth of less than 1 m sample points, only 5. Surface acquisition. Each acquisition is scheduled for 10 min, collected record table, see Appendix B. 5.3.1.5 sample processing. They will be taken to the eggs, larvae, juveniles and all suspended solids and other debris filter together. If the hair Now the eggs, one by one count after culture, during the cultivation species identification, and make relevant records (see Appendix Records Table C). If you find larvae, then into the seven percent solution of formalin fixed, 15 min after picked, by the end of the count, add 5% Formalin preservation. If juveniles placed in 10% formalin solution, fixed save. Each acquisition of the larvae, Juveniles after samples were stored into the tag for the laboratory species identification. Various types of eggs were recorded in each sample, Larvae, juveniles and the number of each end of the development period (recording identification results, see Appendix D). For species identification have questions Samples with ethanol save, molecular identification.

5.3.2 yield Shen sticky eggs of fish resources survey earlier 5.3.2.1 Active collection In moderate flow of water using dip net and other nets, fish spawning grounds and larval and juvenile habitat acquisition. In spawning species of plants for the matrix can be removed plants, plants picked adhered to the sticky eggs; for shallow water as gravel Spawning species matrix, can be sampled directly on the gravel. Shallow nearshore habitats larvae, juveniles collection Available dip net (network Head 0.50 ~ 1.00 mm) acquisition. Accordance with the provisions of HJ 628. 5.3.2.2 passive collection You can set the underlying network, artificial fish nest eggs collected, and follow the HJ 628 regulations. Artificial fish nest means Place the right place for fish spawning habits of the substrate on which to attract fish spawning. For carp, crucian carp spawning in aquatic Fish, plants, or plants with palm Sizha bundles placed in moderate hydrostatic or water area in order to attract fish spawning; for In sediment nesting fish, placed the jar cracks, can attract fish spawning. Drifting downstream with the flow of the viscous Shen fish Eggs, substrate web can be collected. Bottom gear as inverted jiang network, network port for the "D" shaped, conical configuration network to The anchor gear fixed to the bottom, on the edge of the net mouth a buoy system. In the net mouth hanging electronic flow meter, recording start and end readings. And water flow rate through the network port. Before placing the underlying network, determine the flow meter is working properly. When the nets to determine whether the nets Arrived in the river bottom, while nets record time and latitude and longitude. When the net to record the net time. According to observational requirements determine the sampling Time, usually maintained for several hours. 5.3.2.3 Other Standing or slow flow of clear waters directly into the water can be used investigators to collect, observe and count. 5.4 Fish species diversity of survey 5.4.1 catch statistics Various types of water bodies within the district of fishing gear, fishing law fishing catch all kinds of statistics observed. Samples collected in accordance with HJ 628 predetermined execution. 5.4.2 visited and investigate Fishermen, docks, fish markets, restaurants and other places have local fish trade or consumption, or to carry out recreational fishing Side, buy fish specimens were sampled supplement. Samples collected in accordance with the provisions HJ 628. 65.4.3 own collection In shallow water lakes, rivers, coastal zones, mountains, streams, caves, water and other areas on their own collection, to dip net, net, Cage, bait fishing and other sampling methods for collecting fish samples. Samples collected in accordance with the provisions HJ 628. 5.5 Survey catch 5.5.1 Survey Methods Number of Samples 5.5.1.1 catch The number of samples required to be able to catch the reflection of reality catches. When a large number of fishing vessels, according to a variety of fishing gear The number of vessels in proportion sampling; when a small number of fishing vessels, fishing vessels respond catch all statistical analysis. Perennial There are fishing waters job can catch statistics on a monthly basis, while the number of fishing boats and more fishing gear used is inconsistent, the need for fisheries Eligible was subjected to statistical sampling. If a catch from the water more for weighing before and after packing in baskets catch can Twist castration method using a random number table or by means of sampling; when the catch is divided into several units (such as different gear, or batches From net...
